Claims that gravity's effect is felt differently by various wavelengths of light Current belief is light will follow the same set path regardless of frequency If theory is correct, it means that our universe stretches back into time infinitely with no singular point where it started To think that our universe is 13.8 billion years old is incredible enough. But now researchers are proposing that the universe stretches back into time infinitely with no singular point where it started. The idea is one possible result of something known as ‘rainbow gravity’- a theory that is not widely accepted among physicists, though many say the idea is interesting. The theory’s name comes from a suggestion that gravity's effect on the cosmos is felt differently by varying wavelengths of light, which can be found in the colours of the rainbow. THE THEORY OF RAINBOW GRAVITY The Rainbow Gravity theory suggests that gravity's effect on the cosmos causes different wavelengths of light to behave differently. This means that particles with different energies will move in space-times and gravitational fields differently. The theory was proposed 10 years ago in an attempt to reconcile difference between the theories of general relativity and quantum mechanics. One consequence of rainbow gravity is that our universe stretches back into time infinitely with no singular point where it started. The theory was proposed 10 years ago in an attempt to reconcile difference between the theories of general relativity and quantum mechanics. Researchers claim it highlights flaws in the Big Bang theory, which suggests the universe was born about 13.8 billion years ago when an infinitely dense point - known as a 'singularity' - exploded. According to Einstein's general relativity, huge objects warp space-time so that anything travelling through it, such as light (regardless of its frequency), takes a curving path. The Big Bang theory was formulated in 1922 by Alexander Friedmann. Friedmann began with Einstein's equations of general relativity and found a solution to those equations in which the universe began in a state of high density and temperature. In the rainbow theory however, 'particles with different energies will actually see different space-times, different gravitational fields,’ Adel Awad of the Centre for Theoretical Physics at Zewail City of Science and Technology in Egypt told Scientific American. Writing in the Journal of Cosmology and Astroparticle Physics, researchers found two possible beginnings to the universe based on slightly different interpretations of the consequences of rainbow gravity. One result would be that if you retrace time backward, the universe gets denser, approaching an infinite density but never quite reaching it. In the other scenario the universe reaches an extremely high density that's finite and then plateaus. Professor Awad claims that in both scenarios, tracing the path of matter and light in the universe will not cause us to arrive at an infinitely small point of origin, known as the Big Bang Over the next few years, scientists plan to study gamma-ray bursts and other cosmic eventsfor signs of rainbow gravity effects.

Our understanding of the universe in which we live is really just beginning to unfold.
"“Believe nothing merely because you have been told it. Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be kind, conducive to the good, the benefit, the welfare of all beings - that doctrine believe and cling to, and take it as your guide.” ~ Gautama Siddhartha — The Buddha Test of faith...
