"...To illustrate the timing for this domino effect, we will use a sequence of falling billiard balls, where each billiard ball triggers the release of the next billiard ball in the sequence. This assumes pulverization is instantaneous and does not slow down the process. It reality, this pulverization would slow down the “pancake” progression, so longer times would be expected."

"Debunking 'Caveman' conspiracy theories since 2002" Vincent Bugliosi quite correctly described the belief in conspiracies as "poison." It'll obssess and ruin a person's life. Example: Bush was behind 9-11, 1000 Jews didn't show up for work, the planes were remote-controlled, there were no Arabs on board, there were bombs in the towers. People who believe in these things are going to end up just like the loons who for the last 40 years have been trying to prove there were three shooters who assassinated Kennedy. I've met them. 25 books, a stack of papers four feet high...and they've wasted their lives.

People who automatically trust their government totally and completely will one day find out they've been had. That's why you have a mind capable of independent thought. Some, like you, apparently don't use it. Cognitive dissonance is a tough thing for simple minds to overcome.
Welcome to 4.. glad you've joined us..
I agree with what you say, "People who believe in these things ...waste their lives." And lose their country and their freedom.
It seems to me skepticism, even if eventually shown conclusively to be incorrect, is far better than blind acceptance. Skepticism is the fire and anvil on which truth is forged and finally tested. You might even say that without skeptisism, there IS no truth. It is an individual's right, sometimes duty, and potential existential quest to tilt at windmills. The Antigone is fine by me !
9/11 .. it's the science stupid!!
Hi IndieTx, You can relax a bit here...lots of kooks like us LOL....and not the pressure cooker we both know from priors... pull up a chair, sit a spell... LOL............. brer' gotta' run late already !
Seeking the truth is never a waste of either time or money. We know from both common sense and massive amounts of evidence, that Lee Harvey Oswald was not the sole shooter (if indeed he shot at all) of John F. Kennedy. Now exactly what happened, how many people were involved, or how deeply this went both within and without the govt - I don't know. There are many theories, many of which sound plausible. The basic problem here is that we KNOW that the government lied to us and covered this up - for whatever reasons, we can speculate. The government lies to us CONSTANTLY about many issues, and has probably as long as we've had a govt. I think most, if not all, governments lie for various reasons. It is the GOVERNMENT'S OBVIOUS LYING about these and many other events that prompt and fuel the need for independent investigation that results in "conspiracy" theories. By definition, any act that involves more than one person, and which is kept secret, is a conspiracy. The Govt theory of 9/11 is a conspiracy theory. So, perhaps I am misunderstanding your point - are you saying we should simply accept the government's theories of whatever happened, regardless of how plausible it sounds or whatever the science or facts that contradict said theory, in the interest of "saving time"? What happens to the truth then?
"I woke up in the CRAZY HOUSE."
Could someone with a scientific background please summarize this - I understand the assertion about the number of seconds but what would be the conclusion beyond this about the reason for the collapse? Is this author aruing against any controlled demolition? Is she arguing that the buildings collapsed because of the planes? Is there yet another reason for the collapse? I think (probably because of a lack of science background) that I am either missing something here or misinterpreting something.
"I woke up in the CRAZY HOUSE."
Well, look at it this way: There was no pancake collapse. If every floor crashed into every floor below it, etc, it would have fallen 10x slower. I believe her conclusion goes something like this: "So, for the building to be collapsed in about 10 seconds, the lower floors would have to start moving before the upper floors could reach them by gravity alone. Did we see this? I believe it's pretty clear in some of the videos. The "wave" of collapse, progressing down the building, is moving faster than free-fall speed. This would require something like a detonation sequence. Realizing that, for example, the 40th floor needs to start moving before any of the upper floors have "free-fallen" to that point, why would it start moving? There was no fire there. And, if anything, there is less load on that floor as the upper floors turn to dust. "
"Debunking 'Caveman' conspiracy theories since 2002" Ok, thanks, valis - I thought that's what she meant, but it's good to have confirmation :)
"I woke up in the CRAZY HOUSE."
No problem at all.
"Debunking 'Caveman' conspiracy theories since 2002" A fine quote, worthy of committing to memory. The scientific method requires proving a hypothesis. When years of research fail to achieve the desired result, have these researchers "wasted their lives?" Of course not. Without skepticism, not only is there no truth; there is also NO LIBERTY.
Thx. Glad to be here.
No they didn't. Most were paid by the CIA as disinfo artists, the few others actually were reporting the truth. Just like now with 9/11, the CIA is hard at work on the disinfo campaign in a vain attempt to keep the truth from getting out and being accepted. It works, the CIA has excellent propaganda artists, they put the Russians to shame. You can believe people waste their lives trying to get the truth out if you want, but it is actually people like you that are wasting your life by not giving a damn. If you don't live for some meaningful purpose, then why live it at all?
God is always good! The video 9/11 Eyewitness describes this very well. The buildings fell at a rate of speed, equal free fall in a vacuum. Had they collapsed in the way the govt describes, it should have taken far more time. When a building is set with explosives, by professionals, as in a demolition, it will fall at this rate of speed, there is no other way. The video also describes the direction the debris flew is indicative of a demolition. There were even large pieces of metal stuck into the sides of the building next to the WTC, like arrows. This includes WT7, the 3rd building owned by Larry Silverstein that collapsed that day. He is even on video tape saying that he told them to "pull it" (WT7), but he later tries to say that's not what he meant. It only had a couple small fires, but it too fell at a rate of speed that is only explained by a demolition.

Here's a comment that was recently posted at ARG in response to this article, for what it's worth... I've looked into to the speed of callapse issue. In short my conclusions: 1) measurements of the collapse times are not accurate. The seismic data does help out much either. In reality the collapses lasted longer than many believe. 2) If you introduce a contant friction force in opposite direction of gravity as a resistance to losing structural integrity in the building. As if the buildings would collapse at half of normal gravity, the collapse would take 13 seconds. Just a little bit longer than mainstream media told us the collapses lasted and just 4 seconds longer than the 9 seconds it would take in free fall. 3) Total amount of potential energy stored in the building that would be released during collapse is about 1000 GJ and that is a lot. Enough to crush a lot of concrete. But because the structure was slowly crumbling under the load of the debris of the upper floors all this energy would not have been released in a very short moment what would have created one big peak in the seismic data. (Energy = Total mass * gravitational constant * height * 1/2) In those easy SI units: Mass = 510,000,000 kg, height = 417 m, g= 9.81 m/s^2 My conclusion is that however I find the mode of collapse very strange, not something I would have expected, but just looking as the speed of collapse will not give you any evidence of whatever. That doesn't mean I rule out the building got some help in collapsing with explosives for example, but just looking as the collapse speed will never prove your case. I wish some of the 9- 11 video makers would give less attention to the collapse issue and more to the foreknowledge, the myhtic history of Al Qaeda, the Israeli spyring. The FBI informants., the hijackers that turned up to be alive, etc. -- Now my real comment on the model presented on this website: Anybody making any analytic model of the collapsing building would have to make simplifications. But the simplifications in this model just go too far and this makes the outcome unrealistic. This model implies that the falling mass comes to a complete vertical stand still on every floor before making the next floor collapse and so on and so on. Maybe this somewhat realistic for the first few floors that collapsed, but it for sure isn't for the rest of the building. dorrell | 03.15.06 - 8:17 pm | # "Debunking 'Caveman' conspiracy theories since 2002"

Example: bin Laden was behind 911 from a cave in afghanistan, an airplane brought down the entire WTC complex including WTC7, the black boxes weren't found but Atta's passport was intact 4 blocks away, There were WMD's in Iraq, Saddam was behind 911...ad nauseum...
