It could be time to bid the Big Bang bye-bye. Cosmologists have speculated that the Universe formed from the debris ejected when a four-dimensional star collapsed into a black hole — a scenario that would help to explain why the cosmos seems to be so uniform in all directions.

The authors postulate that the 3D Universe we live in might be just such a brane — and that we detect the brane’s growth as cosmic expansion. “Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang — but that is just a mirage,” says Afshordi.

Sigh of relief. I was worried that they were cancelling Sheldon, Leonard and Penny.

I'd  have posted that in the Holodeck forum.

It's an interesting idea. Just because it could account for temperature equilibrium doesn't make it so though.

Absolutely.  It has to do more than just explain current and past observations it needs to be used to predict future ones better than competing theories.  If it can't be used to make predictions that can be tested then it hardly qualifies as a theory, more a hypothesis.
