Could Our Universe Have Arisen From A Black Hole?
“As the black hole first formed, from a star’s core imploding and collapsing, the event horizon first came to be, then rapidly expanded and continued to grow in area as more and more matter continued to fall in. If you were to put a coordinate grid down on this two-dimensional wrapping, you would find that it originated where the gridlines were very close together, then expanded rapidly as the black hole formed, and then expanded more and more slowly as matter fell in at a much lower rate. This matches, at least conceptually, what we observe for the expansion rate of our three-dimensional Universe.”
There are only two types of singularities that General Relativity predicts the existence of in our Universe: one at the centers of black holes, which form from the collapse of matter, and one at the very birth of space and time, at the origin of it all. All of the information that falls into a black hole from our 3D Universe gets encoded on the black hole’s 2D event horizon, which is both fascinating and one of the main components of the black hole information paradox. But it makes one wonder, with a little creative thinking, whether our 3D Universe didn’t result from the formation of a much more massive black hole in higher-dimensional space? Although the idea sounds a little bit out there, there’s a lot of theoretical reasons to believe this might be legitimate. And the closer we get to quantum gravity, the closer we get to testing whether this might actually reflect our reality.
The Universe could, in principle, have arisen from a higher-dimensional black hole, and we might be creating mini, 2D Universes with each new black hole our Universe forms!
