Critics of biblical creation sometimes use distant starlight as an argument against a young universe. The argument goes something like this: (1) there are galaxies that are so far away, it would take light from their stars billions of years to get from there to here; (2) we can see these galaxies, so their starlight has already arrived here; and (3) the universe must be at least billions of years old—much older than the 6,000 or so years indicated in the Bible. Many big bang supporters consider this to be an excellent argument against the biblical timescale. But when we examine this argument carefully, we will see that it does not work. The universe is very big and contains galaxies that are very far away, but that does not mean that the universe must be billions of years old. The distant starlight question has caused some people to question cosmic distances. “Do we really know that galaxies are so far away? Perhaps they are much closer, so the light really doesn’t travel very far.”1 However, the techniques that astronomers use to measure cosmic distances are generally logical and scientifically sound. They do not rely on evolutionary assumptions about the past. Moreover, they are a part of observational science (as opposed to historical/origins science); they are testable and repeatable in the present. You could repeat the experiment to determine the distance to a star or galaxy, and you would get approximately the same answer. So we have good reason to believe that space really is very big. In fact, the amazing size of the universe brings glory to God (Psalm 19:1). Some Christians have proposed that God created the beams of light from distant stars already on their way to the earth. After all, Adam didn’t need any time to grow from a baby because he was made as an adult. Likewise, it is argued that the universe was made mature, and so perhaps the light was created in-transit. Of course, the universe was indeed made to function right from the first week, and many aspects of it were indeed created “mature.” The only problem with assuming that the light was created in-transit is that we see things happen in space. For example, we see stars change brightness and move. Sometimes we see stars explode. We see these things because their light has reached us. But if God created the light beams already on their way, then that means none of the events we see in space (beyond a distance of 6,000 light-years) actually happened. It would mean that those exploding stars never exploded or existed; God merely painted pictures of these fictional events. It seems uncharacteristic of God to make illusions like this. God made our eyes to accurately probe the real universe; so we can trust that the events that we see in space really happened. For this reason, most creation scientists believe that light created in-transit is not the best way to respond to the distant starlight argument. Let me suggest that the answer to distant starlight lies in some of the unstated assumptions that secular astronomers make. The Assumptions of Light Travel-time Arguments Any attempt to scientifically estimate the age of something will necessarily involve a number of assumptions. These can be assumptions about the starting conditions, constancy of rates, contamination of the system, and many others. If even one of these assumptions is wrong, so is the age estimate. Sometimes an incorrect worldview is to blame when people make faulty assumptions. The distant starlight argument involves several assumptions that are questionable—any one of which makes the argument unsound. Let’s examine a few of these assumptions. The Constancy of the Speed of Light It is usually assumed that the speed of light is constant with time.2 At today’s rate, it takes light (in a vacuum) about one year to cover a distance of 6 trillion miles. But has this always been so? If we incorrectly assume that the rate has always been today’s rate, we would end up estimating an age that is much older than the true age. But some people have proposed that light was much quicker in the past. If so, light could traverse the universe in only a fraction of the time it would take today. Some creation scientists believe that this is the answer to the problem of distant starlight in a young universe. However, the speed of light is not an “arbitrary” parameter. In other words, changing the speed of light would cause other things to change as well, such as the ratio of energy to mass in any system.3 Some people have argued that the speed of light can never have been much different than it is today because it is so connected to other constants of nature. In other words, life may not be possible if the speed of light were any different. This is a legitimate concern. The way in which the universal constants are connected is only partially understood. So, the impact of a changing speed of light on the universe and life on earth is not fully known. Some creation scientists are actively researching questions relating to the speed of light. Other creation scientists feel that the assumption of the constancy of the speed of light is probably reasonable and that the solution to distant starlight lies elsewhere. The Assumption of Rigidity of Time Many people assume that time flows at the same rate in all conditions. At first, this seems like a very reasonable assumption. But, in fact, this assumption is false. And there are a few different ways in which the nonrigid nature of time could allow distant starlight to reach earth within the biblical timescale. Albert Einstein discovered that the rate at which time passes is affected by motion and by gravity. For example, when an object moves very fast, close to the speed of light, its time is slowed down. This is called “time-dilation.” So, if we were able to accelerate a clock to nearly the speed of light, that clock would tick very slowly. If we could somehow reach the speed of light, the clock would stop completely. This isn’t a problem with the clock; the effect would happen regardless of the clock’s particular construction because it is time itself that is slowed. Likewise, gravity slows the passage of time. A clock at sea-level would tick slower than one on a mountain, since the clock at sea-level is closer to the source of gravity. It seems hard to believe that velocity or gravity would affect the passage of time since our everyday experience cannot detect this. After all, when we are traveling in a vehicle, time appears to flow at the same rate as when we are standing still. But that’s because we move so slowly compared to the speed of light, and the earth’s gravity is so weak that the effects of time-dilation are correspondingly tiny. However, the effects of time-dilation have been measured with atomic clocks. Since time can flow at different rates from different points of view, events that would take a long time as measured by one person will take very little time as measured by another person. This also applies to distant starlight. Light that would take billions of years to reach earth (as measured by clocks in deep space) could reach earth in only thousands of years as measured by clocks on earth. This would happen naturally if the earth is in a gravitational well, which we will discuss below. Many secular astronomers assume that the universe is infinitely big and has an infinite number of galaxies. This has never been proven, nor is there evidence that would lead us naturally to that conclusion. So, it is a leap of “blind” faith on their part. However, if we make a different assumption instead, it leads to a very different conclusion. Suppose that our solar system is located near the center of a finite distribution of galaxies. Although this cannot be proven for certain at present, it is fully consistent with the evidence; so it is a reasonable possibility. In that case, the earth would be in a gravitational well. This term means that it would require energy to pull something away from our position into deeper space. In this gravitational well, we would not “feel” any extra gravity, nonetheless time would flow more slowly on earth (or anywhere in our solar system) than in other places of the universe. This effect is thought to be very small today; however, it may have been much stronger in the past. (If the universe is expanding as most astronomers believe, then physics demands that such effects would have been stronger when the universe was smaller). This being the case, clocks on earth would have ticked much more slowly than clocks in deep space. Thus, light from the most distant galaxies would arrive on earth in only a few thousand years as measured by clocks on earth. This idea is certainly intriguing. And although there are still a number of mathematical details that need to be worked out, the premise certainly is reasonable. Some creation scientists are actively researching this idea. Assumptions of Synchronization Another way in which the relativity of time is important concerns the topic of synchronization: how clocks are set so that they read the same time at the same time.4 Relativity has shown that synchronization is not absolute. In other words, if one person measures two clocks to be synchronized, another person (moving at a different speed) would not necessarily measure those two clocks to be synchronized. As with time-dilation, this effect is counterintuitive because it is too small to measure in most of our everyday experience. Since there is no method by which two clocks (separated by a distance) can be synchronized in an absolute sense, such that all observers would agree regardless of motion, it follows that there is some flexibility in how we choose what constitutes synchronized clocks. The following analogy may be helpful. Imagine that a plane leaves a certain city at 4:00 p.m. for a two-hour flight. However, when the plane lands, the time is still 4:00. Since the plane arrived at the same time it left, we might call this an instantaneous trip. How is this possible? The answer has to do with time zones. If the plane left Kentucky at 4:00 p.m. local time, it would arrive in Colorado at 4:00 p.m. local time. Of course, an observer on the plane would experience two hours of travel. So, the trip takes two hours as measured by universal time. However, as long as the plane is traveling west (and providing it travels fast enough), it will always naturally arrive at the same time it left as measured in local time. There is a cosmic equivalent to local and universal time. Light traveling toward earth is like the plane traveling west; it always remains at the same cosmic local time. Although most astronomers today primarily use cosmic universal time (in which it takes light 100 years to travel 100 light-years), historically cosmic local time has been the standard. And so it may be that the Bible also uses cosmic local time when reporting events. Since God created the stars on Day 4, their light would leave the star on Day 4 and reach earth on Day 4 cosmic local time. Light from all galaxies would reach earth on Day 4 if we measure it according to cosmic local time. Someone might object that the light itself would experience billions of years (as the passenger on the plane experiences the two hour trip). However, according to Einstein’s relativity, light does not experience the passage of time, so the trip would be instantaneous. Now, this idea may or may not be the reason that distant starlight is able to reach earth within the biblical timescale, but so far no one has been able to prove that the Bible does not use cosmic local time. So, it is an intriguing possibility.5 The Assumption of Naturalism One of the most overlooked assumptions in most arguments against the Bible is the assumption of naturalism. Naturalism is the belief that nature is “all that there is.” Proponents of naturalism assume that all phenomena can be explained in terms of natural laws. This is not only a blind assumption, but it is also clearly antibiblical. The Bible makes it clear that God is not bound by natural laws (they are, after all, His laws). Of course God can use laws of nature to accomplish His will; and He usually does so. In fact, natural laws could be considered a description of the way in which God normally upholds the universe. But God is supernatural and is capable of acting outside natural law. This would certainly have been the case during Creation Week. God created the universe supernaturally. He created it from nothing, not from previous material (Hebrews 11:3). Today, we do not see God speaking into existence new stars or new kinds of creatures. This is because God ended His work of creation by the seventh day. Today, God sustains the universe in a different way than how He created it. However, the naturalist erroneously assumes that the universe was created by the same processes by which it operates today. Of course it would be absurd to apply this assumption to most other things. A flashlight, for example, operates by converting electricity into light, but the flashlight was not created by this process. Since the stars were created during Creation Week and since God made them to give light upon the earth, the way in which distant starlight arrived on earth may have been supernatural. We cannot assume that past acts of God are necessarily understandable in terms of a current scientific mechanism, because science can only probe the way in which God sustains the universe today. It is irrational to argue that a supernatural act cannot be true on the basis that it cannot be explained by natural processes observed today. It is perfectly acceptable for us to ask, “Did God use natural processes to get the starlight to earth in the biblical timescale? And if so, what is the mechanism?” But if no natural mechanism is apparent, this cannot be used as evidence against supernatural creation. So, the unbeliever is engaged in a subtle form of circular reasoning when he uses the assumption of naturalism to argue that distant starlight disproves the biblical timescale. Light Travel-Time: A Self-Refuting Argument Many big bang supporters use the above assumptions to argue that the biblical timescale cannot be correct because of the light travel-time issue. But such an argument is self-refuting. It is fatally flawed because the big bang has a light travel-time problem of its own. In the big bang model, light is required to travel a distance much greater than should be possible within the big bang’s own timeframe of about 14 billion years. This serious difficulty for the big bang is called the “horizon problem.” 6 The following are the details. Figure 1 & 2 The Horizon Problem In the big bang model, the universe begins in an infinitely small state called a singularity, which then rapidly expands. According to the big bang model, when the universe is still very small, it would develop different temperatures in different locations (Figure 1). Let’s suppose that point A is hot and point B is cold. Today, the universe has expanded (Figure 2), and points A and B are now widely separated. However, the universe has an extremely uniform temperature at great distance— beyond the farthest known galaxies. In other words, points A and B have almost exactly the same temperature today. We know this because we see electromagnetic radiation coming from all directions in space in the form of microwaves. This is called the “cosmic microwave background” (CMB). The frequencies of radiation have a characteristic temperature of 2.7 K (-455°F) and are extremely uniform in all directions. The temperature deviates by only one part in 105. The problem is this: How did points A and B come to be the same temperature? They can do this only by exchanging energy. This happens in many systems: consider an ice cube placed in hot coffee. The ice heats up and the coffee cools down by exchanging energy. Likewise, point A can give energy to point B in the form of electromagnetic radiation (light), which is the fastest way to transfer energy since nothing can travel faster than light. However, using the big bang supporters’ own assumptions, including uniformitarianism and naturalism, there has not been enough time in 14 billion years to get light from A to B; they are too far apart. This is a light travel-time problem—and a very serious one. After all, A and B have almost exactly the same temperature today, and so must have exchanged light multiple times. Big bang supporters have proposed a number of conjectures which attempt to solve the big bang’s light travel-time problem. One of the most popular is called “inflation.” In “inflationary” models, the universe has two expansion rates: a normal rate and a fast inflation rate. The universe begins with the normal rate, which is actually quite rapid, but is slow by comparison to the next phase. Then it briefly enters the inflation phase, where the universe expands much more rapidly. At a later time, the universe goes back to the normal rate. This all happens early on, long before stars and galaxies form. The inflation model allows points A and B to exchange energy (during the first normal expansion) and to then be pushed apart during the inflation phase to the enormous distances at which they are located today. But the inflation model amounts to nothing more than storytelling with no supporting evidence at all. It is merely speculation designed to align the big bang to conflicting observations. Moreover, inflation adds an additional set of problems and difficulties to the big bang model, such as the cause of such inflation and a graceful way to turn it off. An increasing number of secular astrophysicists are rejecting inflation for these reasons and others. Clearly, the horizon problem remains a serious light travel-time problem for the big bang. The critic may suggest that the big bang is a better explanation of origins than the Bible since biblical creation has a light travel-time problem—distant starlight. But such an argument is not rational since the big bang has a light travel-time problem of its own. If both models have the same problem in essence7, then that problem cannot be used to support one model over the other. Therefore, distant starlight cannot be used to dismiss the Bible in favor of the big bang. Conclusions So, we’ve seen that the critics of creation must use a number of assumptions in order to use distant starlight as an argument against a young universe. And many of these assumptions are questionable. Do we know that light has always propagated at today’s speed? Perhaps this is reasonable, but can we be absolutely certain, particularly during Creation Week when God was acting in a supernatural way? Can we be certain that the Bible is using “cosmic universal time,” rather than the more common “cosmic local time” in which light reaches earth instantly? We know that the rate at which time flows is not rigid. And although secular astronomers are well aware that time is relative, they assume that this effect is (and has always been) negligible, but can we be certain that this is so? And since stars were made during Creation Week when God was supernaturally creating, how do we know for certain that distant starlight has arrived on earth by entirely natural means? Furthermore, when big bang supporters use distant starlight to argue against biblical creation, they are using a self-refuting argument since the big bang has a light travel-time problem of its own. When we consider all of the above, we see that distant starlight has never been a legitimate argument against the biblical timescale of a few thousand years. As creation scientists research possible solutions to the distant starlight problem, we should also remember the body of evidence that is consistent with the youth of the universe. We see rotating spiral galaxies that cannot last multiple billions of years because they would be twisted-up beyond recognition. We see multitudes of hot blue stars, which even secular astronomers would agree cannot last billions of years.8 In our own solar system we see disintegrating comets and decaying magnetic fields that cannot last billions of years; and there is evidence that other solar systems have these things as well. Of course, such arguments also involve assumptions about the past. That is why, ultimately, the only way to know about the past for certain is to have a reliable historic record written by an eyewitness. That is exactly what we have in the Bible.

You're exactly right. But there is "logic, or reason, or theory or experiment or rational thought or discussion. " and worldly "christians" are not honestly capable of doing it. This is so typical, and there is no reason for any of it. It drives me nuts. It's as if somehow Gods' existence will somehow be scientifically disproven, and they're worried, so they give science a bad name. A preemptive strike, if you will.
Click for Privacy and Preparedness files Actually, it is said that space and time didn't exist before the Big Bang. The expansion is actually the expansion of space within the big bang singularity, where the universe could be seen as a ballon, and space is the air inside it, simply speaking anyways...
Starling?
Click for Privacy and Preparedness files Is that what you believe?
I fixed it.
Yes, if you mean anything older than 6000 years, considering the age is in billions of year, not thousands, not millions, but billions...
The big bang theory is outdated. You should keep up. On the Silliness of the Big Bang Hypothesis Miriam English Look out into deep space and you'll see objects whose light left them a long time ago ago. In 1929 Edwin Hubble published his finding of redshifts in the light of distant objects. The more distant an object was, the greater its redshift. It seemed natural to many to assume that this redshift is the result of those objects speeding away from us. This always struck me as simplistic. The reasoning goes this way: If all these things are speeding away from each other, then in the past they must have been closer together. Extrapolating backwards, so the thinking goes, you should reach some point of origin -- the source of the universe! This seems incredibly naïve, and doesn't actually explain anything. It uses an unproven assumption (that redshift is attributable solely to velocity) and some unknown mechanism to create all of the universe in a split second. You might as well believe in some grey-haired old man in the sky who did it all like in Genesis!! According to the Big Bang hypothesis there should be a limit to how far "back in time" we can look when viewing distant objects. If objects can be seen "further back" than that limit, would it disprove the Big Bang? No. The Big Bang is not science, because there is no clear way to disprove it. In that respect it is like a religion. Finding older objects out there simply revises the "age" of the universe. This has happened before, when we got better telescopes that could see more distant objects, and it will happen again, each time we can see further. One thing proponents of the Big Bang like to say is that space itself is expanding. But if space inflated like a balloon we would notice no change as we would be inflating with all the other space around and within us. Dimension is only good for measuring things against other things. If everything has expanded then nothing has changed! Of course, these people generally shift gear at this point and say they don't mean that space itself expands (even though it is actually what they say), they mean that the distance between objects has expanded, but that objects themselves are held together by gravity and electromagnetic forces. If that's so then they're guilty of using a spooky way of saying something mundane in order to give it a mystical gloss. An unexpected aspect is that if space really was expanding then it seems to me that this might actually prevent the redshift occurring in the first place! If space expands, but the things in it remain the same size, then would light waves remain the same size too? If space is expanding then is there even any doppler effect? Because now the objects aren't moving through space at all. Probably the most abhorrent of all is the reintroduction of a single center for the universe. Aristotle strikes again! After Europe was the center of the world, we found out oops, Earth is round; there is no center. So then the Earth was the center of the universe, but oops! No, we orbit the sun. So our sun is the center of the universe. But oops again, we find that the stars out there are billions of other suns just like ours. So then our galaxy must be the center of the universe, but oops! we find that there are countless other galaxies out there. Each time we set a center we are forced to to rethink. Quite frankly, the idea that there could be any center in time or space seems to me totally absurd! I really don't understand people's difficulty with infinity. The Big Bang people have learned to be incredibly slippery, and many will protest that there is no central point in the universe that it all came from, that all this is the center, because it all came from the same event. But this is just playing with words. You can ask them how big the universe supposed is to be now, and they'll come up with a number (about 12 billion light years across). Then you can ask them how big it was 6 billion years ago, and they'll come up with a smaller number. You can ask them how big it was 11 billion years ago and they'll give you an even smaller number. You can ask them how big the universe was when it was a billionth of a second old, and they'll give you a very small number. Yet they hate being pinned down to saying that the universe has a center. O.K. So getting back to the redshift, how else can we explain it? Well, space is not empty; there is lots of gas and dust, and gravitational and magnetic fields out there. I find it difficult to believe that light would travel millions, or billions of years through all that without losing some energy. Light waves, unlike sound waves, can't dissipate energy by losing intensity so they would have to fall in frequency. We would see this as, surprise, surprise, a redshift. There is another possible cause of light losing energy over those immense distances. Low frequency electromagnetic waves spread out as they travel. The higher the frequency, the less this spread is and the tighter the beam. Might not the waves that are individual visible light photons spread very slightly over the cosmic distances they travel? And as they spread, they lose energy. As pointed out earlier, a quantum of light can't lose energy in intensity so the only way for it to dissipate energy is to drop in frequency. Redshift. I am not saying that all redshift is due to energy loss from these sources and none is due to doppler. But I do think that jumping to a conclusion that creates the entire universe in an instant from some unknowable magic is a bit hard to swallow! To believe that redshift results solely from velocities would appear to lead us to either the Big Bang or Steady State. While I find the Steady State more appealing (and it has been by no means disproved, contrary to what the prevailing dogma would have you believe) it too invokes spontaneous creation of matter. And I have seen no evidence of this happening either gradually (Steady State) or suddenly (Big Bang). If the redshift is simply light losing energy on its way through space then there is no need for either. What of the microwave background radiation? Leave aside the fact that it is not a vindication of the Big Bang (in fact was considered a disproof of it when it was found to be "lumpy" but theories were tweaked and the Big Bang bent to fit). If light is dropping in frequency over vast distances I expect it would reach microwave frequncies. Does this explain it? I don't know, but I find the idea of "fossil radiation" still hanging around from the point of creation to be a bit dumb. Isn't this supposed to be travelling at the speed of light? And we have been travelling outward at less than the speed of light. That means the wavefront is racing ahead of us doesn't it? Some people will say that the waves curve around back to us. But that doesn't make sense. We continue to escape the gravity well and fly outward, but for some reason the microwave radiation which has been travelling just as long as we have, can't?? Anyway that's a circular argument (no pun intended); it relies on the matter in the universe occupying a limited volume, as if it expanded out from a central point. You can't use it to "prove" itself. After all that, please understand that I'm not saying that there definitely was no big bang to create the local or observable universe. I'm just saying that the evidence is too thin to conclude that it did. The information we have could point in a number of different directions, if we let it. The Steady State is one such possibility. To jump to conclusions and simply believe that there was a big bang is a big mistake. There are too many things which don't sound right. * The entire universe created in an instant by magic (what would you call an unknown and possibly unknowable event?). * All this energy and matter escaping an incredible gravity well. * The illogical idea that space itself is expanding. * The reintroduction of a singular central point in time and space for the start of the universe. * The microwave background radiation somehow hanging around from the big event instead of speeding off away from us. If it looks like a duck and sounds like a duck and smells like a duck... I think it smells like a very dead one. Note: You may have noticed that I referred to the Big Bang as a hypothesis, not a theory. This is because a theory is a statement or proposition that is proved by logical reasoning from given facts and justifiable assumptions. That's like the theory of evolution, which is clearly a fact because we see it in action every day and can prove it logically any number of ways. In contrast a hypothesis is merely a supposition put forward in explanation of observed facts. Until we can logically prove the creation of everything from it, the Big Bang must remain a hypothesis. (The two definitions above came from the Penguin Dictionary of Science, by E.B. Uvarov and Alan Isaacs, 7th Edition.) http://miriam-english.org/articles/sillyBigBang.html
Yes, How so. Scientifically prove it.
This is over your head. But here One thing proponents of the Big Bang like to say is that space itself is expanding. But if space inflated like a balloon we would notice no change as we would be inflating with all the other space around and within us. Dimension is only good for measuring things against other things. If everything has expanded then nothing has changed!

Because now the objects aren't moving through space at all.
Yes. And prove it? You want me to reinvent the wheel? It's already been proven by people a lot smarter about it than I am. To ask anyone to prove it all over again is silly, IMO.
Click for Privacy and Preparedness files So your answer is someone smarter then you told you so and you believe it. Well that proves absolutely nothing. I guess from now on we should all just cut and paste our opinions.
I'll believe the physicists who study and research these things rather than a blogger without a clue of what she's talking about... I found this interesting BTW; There are too many things which don't sound right. * The entire universe created in an instant by magic Well gee whiz Old Friend, isn't that what you believe? The argument here isn't IF it happened, it's WHEN and HOW...
OK, I await your check in the amount of, oh, lets say $100,000. That will get me started in college. But be very prepared to write more checks. VERY prepared. Then, I will await another check for, say, 1.5 million dollars for the necessary equipment. But again, that is an estimate. Keep that checkbook handy. Then there's rental time on an observatory that you need to pay for. I hear that's not cheap either. That = even more checks. I hope you have deep pockets.
Click for Privacy and Preparedness files I'll believe the physicists who study and research these things The argument is the authority of Gods word. You also just admitted that you don't know what you are talking about and just believe it because he is a "physicist who study and research these things" You take it on faith. Distant starlight is not proof of an old universe. You have failed to make your case. That would mean that I win by default.
Then, I will await another check for, say, 1.5 million dollars for the necessary equipment. But again, that is an estimate. Keep that checkbook handy. Then there's rental time on an observatory that you need to pay for. I hear that's not cheap either. That = even more checks. I hope you have deep pockets. You really think that you have to do all that in order to prove that distant light proves an old universe? It is not that complicated. God could very well have created the universe in working order. Couldn't he have done that? If you say he couldn't have done that I would like to know why. If you admit the truth, that he very well could have, then that would mean that distant starlight doesn't prove squat.
Don't ask me why He did so. It's kind of inconvenient for everybody.
Yes. You asked me to prove it all over again. That is what it would take to prove it all over again. Tell me, what level of "proof" would suffice? Keeping in mind that there are no eyewitnesses. All we have are scientific laws that God set up to teach us about His creation. He conceals it, we find it. Like I said in your other post, it's not a science vs God fight.
Click for Privacy and Preparedness files It is not possilbe to disprove a young earth using the basis that we see light from stars that are light years away. You have to make assumptions to come to that conclusion. You have to assume that universe wasn't completed in working order. It don't take anything more then your mind to determine that FACT.
Oh yes it is. When you accept evolution as fact you are saying Gods word isn't true and reliable. That doesn't mean we shouldn't seek to prove Gods word is truly is his word. It just means that evolution and this millions of years crap is just that junk science crap. Not science at all.
Yes it is. But that level of proof will not be good enough for you. Which is why I asked you what kind of proof you would accept. YOU have to make assumptions to come to any other conclusion. YOU have to assume the speed of light changed, gravity changed, etc. Or YOU have to assume God created it all without regard to scientific laws HE created in the first place. I dont have to assume any such thing.
Click for Privacy and Preparedness files Evolution is a different topic. I don't buy the evolution argument either. THings adapt and change, but you dont get 1 kind of animal from another kind of animal much less any kind of creature from some kind of ooze being hit by lightning..
Click for Privacy and Preparedness files Do you think every astrophysicist in the world is a moron? Look, light travels 186,000 miles per second. So that means it travels 5,865,696,000,000 (5.8 trillion) miles in a year. The sun is 93 million miles away from Earth. So the sun is 1/63,000 of a light year away from Earth, or 1 astronomical unit (AU). Likewise, light travels 63,000 AU in one year. Incidently, the furthest known solar planet is Pluto, which is at its most distant 49 AU away. Thus, in your theory, the entire universe could only have a diameter of 2 * 6000 * 63,000 AU, or 252 million AU. With all of the planets, stars, and galaxies that we can see, the gravitational attraction between them would be so great if they were to fit into this little ball of space your theory postulates, then the universe would collapse upon itself. It certainly wouldn't be expanding. As it is, it is not so small, where the furthest galaxies can be seen out to about 12 billion light years away, or 756 trillion AU, meaning the observable universe is at least 1512 TRILLION AU in radius, about 6 million times larger than your theory allows for. For information on how the distance of stars and galaxies are determined, read this... It is different to a degree. But these junk sciences all lean on each other. This junk science starlight hypothosis gives credence to billions of years. Then some other "scientist" bases his theories on it. And so on.
Proof would be certainty. Like 1 + 1 = 2. Can't be done. Admit it.
So you can determine distance. No one disagrees with that. Doesn't prove the universe is old.
Whoever wrote this doesn't understand relativity at all. If we could move a clock at the speed of light, it would still tick at a "normal" speed provided we moved with the clock. It would only slow down from the point of view of a reference observing it. The same is true for a clock in a gravitational field - if you are in the same field, the clock acts as if there is no gravity at all. And when he talks about the colors and distances of stars, it's clear that the loon has never heard of redshift. These guys should stick to thumping their Bibles and stop embarassing themselves with rhetoric that wouldn't impress anyone with a high school science education.
Read the link I provided. If you can't understand it, or refuse to even read what it says, then I'm not going to waste my time trying to explain it all to you.
In other words - Astronomers are all wrong. Geologists are all wrong. Physicists are all wrong. Chemists are all wrong. Biologists are all wrong. They're either all ignorant, or there's a grand conspiracy to cover up the truth - aka the myths of 2 millenium BC Jewish goat herders and Old Friend's Church of Zion. Sorry, but things that we can actually measure (isotope content, wavelengths of light) will trump fairy tales for most reasonable people.
I know he's just phd and has written and published several books. He doesn't know squat compared to you.
The best example of sophistry is this: That is why, ultimately, the only way to know about the past for certain is to have a reliable historic record written by an eyewitness. That is exactly what we have in the Bible So then, I guess I should go looking for Cyclopses off the coast of Greece. Homer's ODYSSEY says so, a historical record of people WHO WERE THERE. That's the logic of Biblical literalists, pure and simple. I suppose it also means that we can never convict criminals based on physical evidence. If we can't use redshift or isotope decay to say things about the history of the universe and the earth, we can't use blood, DNA, or fingerprint evidence in criminal courts either. Why. Because "the only way to know about the past is from eyewitnesses."
He makes mistakes when discussing light spectra and relativity that an average high school kid wouldn't make. Let me guess - his PhD is from the Creation "Science" institute. Right up there with mail order diplomas.

No in other words you are wrong. The author of this piece is an astronomer. As for the other fields opinion is varied there too.
If the distance is correct, then how do you think light from a star further away than 6000 light years gets here? If that object is measured to be 6 MILLION light years away, how do you explain it's light at all? The fact is, the earth didn't start to revolve around the sun when men started sending satellites into space, just as the stars didn't start emitting light from 14 BILLION light years away 6000 years ago.
Who is the eyewitness who wrote Genesis I wonder? Are they trying to say a man lived back then to see it all happen, and wrote it down in a book?
It travels here at the speed of light. Big deal. Now tell me why God couldn't have created his world complete. Meaning the starlight was already visible to the people here. To use for seasons etc. Why are you limiting what God can do? Why is that impossible?
Various people carried it orally and possibly written too. Until someone like Moses put it together for the people. That is my take. Could be wrong.
I what way is the Book of Genesis any more an eye witness account than Homer's Odyssey or the Thousand and One Nights? Only a lunatic would use ancient Greek myths or Arab/Persian fairy tales as a serious source on science or history. How are Jewish myths and fairy tales any different?
No! Who gives a shit anyway. It just proves that the batteries are run down and that they should have used the copper topped battery.
No! Damn boy. You have some sense after all. Starlight doesn't prove a young or an old universe. They don't get that it isn't proveable.
Well you should. Since some of your beliefs ahem evolution are partially based on that junk science. Maybe you should take another look at some of those beliefs.
That is absolute horse manure. The person who wrote this apparently doesn't realize that just because light travels at the speed it does doesn't mean it takes less time to reach it's destination, it means a PARTICLE traveling at the speed of light would not experience time. However, light STILL takes as long as it does to reach its destination. If such weren't true, we wouldn't be able to bounce a laser off a distant object and measure it's distance by the amount of time it takes for it to be reflected, as it would take no time at all for the light to travel. In fact, it'd be instananeous. Einstein's theories state that time dilation occurs as an OBJECT consisting of matter approaches the speed of light, NOT light itself.

In the big bang model, the universe begins in an infinitely small state called a singularity, which then rapidly expands. According to the big bang model, when the universe is still very small, it would develop different temperatures in different locations (Figure 1). Let’s suppose that point A is hot and point B is cold. Today, the universe has expanded (Figure 2), and points A and B are now widely separated.

Actually, it is said that space and time didn't exist before the Big Bang. The expansion is actually the expansion of space within the big bang singularity, where the universe could be seen as a ballon, and space is the air inside it, simply speaking anyways...

So your answer is someone smarter then you told you so and you believe it. Well that proves absolutely nothing. I guess from now on we should all just cut and paste our opinions.

This is called “time-dilation.” So, if we were able to accelerate a clock to nearly the speed of light, that clock would tick very slowly. If we could somehow reach the speed of light, the clock would stop completely. This isn’t a problem with the clock; the effect would happen regardless of the clock’s particular construction because it is time itself that is slowed. Likewise, gravity slows the passage of time. A clock at sea-level would tick slower than one on a mountain, since the clock at sea-level is closer to the source of gravity

Since time can flow at different rates from different points of view, events that would take a long time as measured by one person will take very little time as measured by another person. This also applies to distant starlight. Light that would take billions of years to reach earth (as measured by clocks in deep space) could reach earth in only thousands of years as measured by clocks on earth. This would happen naturally if the earth is in a gravitational well, which we will discuss below.
