Did a Collapsing 4 Dimensional Star Spawn 'The Big Bang?'
Canadian astrophysicist Niayesh Afshordi and his colleagues have turned to an idea first proposed 13 years ago. In that model, our 3D universe is merely a membrane- also known as a brane- floating through a 4D “bulk universe.”
There could be a gaping hole in the Big Bang theory. Or rather, a giant, colossal black-hole caused by the collapse of a four-dimensional star. One of the main problems with the Big Bang is that the temperature of the universe is nearly uniform.
