A universe without a big bang?

Could Stephen Hawking be wrong?  Wun-Yi Shu, an associate professor at National Tsing Hua University in Taiwan, has proposed a new cosmological model that is able to describe the universe as well as Big Bang theory can, but without having to rely on a big bang, a big crunch or dark energy.

And the best part? In Shu’s model the speed of light and the gravitational “constant” are not constant! Instead, they vary with the evolution of the universe.  (Is that a loophole big enough for intergalactic travel in our future?)

Basically, Shu proposes that time and space can be converted into one another using a varying speed of light as the conversion factor. He thinks that mass and length should also be interchangeable, using a varying gravitational “constant” and a varying speed of light as conversion factors as well.

Essentially, time is converted into space and mass is converted into length, as the universe expands.
