Big Bang Abandoned in New Model of the Universe
A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the 
universe has no beginning and no end.

As one of the few astrophysical events that most people are familiar with, the Big Bang has a special place in our 
culture. And while there is scientific consensus that it is the best explanation for the origin of the Universe, the 
debate is far from closed. However, it's hard to find alternative models of the Universe without a beginning that are 
genuinely compelling.

That could change now with the fascinating work of Wun-Yi Shu at the National Tsing Hua University in Taiwan. Shu has 
developed an innovative new description of the Universe in which the roles of time space and mass are related in new 
kind of relativity.

Shu's idea is that time and space are not independent entities but can be converted back and forth between each other. 
In his formulation of the geometry of spacetime, the speed of light is simply the conversion factor between the two. 
Similarly, mass and length are interchangeable in a relationship in which the conversion factor depends on both the 
gravitational constant G and the speed of light, neither of which need be constant.

So as the Universe expands, mass and time are converted to length and space and vice versa as it contracts.

This universe has no beginning or end, just alternating periods of expansion and contraction. In fact, Shu shows that 
singularities cannot exist in this cosmos.

It's easy to dismiss this idea as just another amusing and unrealistic model dreamed up by those whacky comsologists.

That is until you look at the predictions it makes. During a period of expansion, an observer in this universe would 
see an odd kind of change in the red-shift of bright objects such as Type-I supernovas, as they accelerate away. It 
turns out, says Shu, that his data exactly matches the observations that astronomers have made on Earth.
