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.

Stephen Hawking agrees that aliens won’t be friendly

Remember Simon Conway Morris?  He was the guy who warned of the potential threat that extra-terrestrials could pose to our planet.  Well apparently he’s been backed up by British astrophysicist Stephen Hawking. The CBC is reporting today that Hawking warns about the dangers of communicating with aliens in an up-coming Discovery Channel documentary.  This is essentially the same warning that Morris gave at a conference of the Royal Society in London back in January.

It must be quite an ego boost for Morris – it’s not every day that a legendary genius agrees with your theories.

I, on the other hand, still think that even the arrival of peaceful aliens would be devastating for the human race. We don’t take well to outsiders.
