“Man is something that shall be overcome. Man is a rope,tied between beast and overman – a rope over an abyss.What is great in man is that he is a bridge and not an end.” -Friedrich Nietzsche
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.
The bigger a black hole’s mass, the larger the area of its event horizon is. The quasar illustrated here has a black hole of 2 billion Solar Masses. Could a 4D black hole of ~10^25 solar masses or more been the source of our Universe? Image credit: ESO/M. Kornmesser.
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.
A singularity is where conventional physics breaks down, whether you’re talking about the very beginning of the Universe and the birth of space and time or the very central point of a black hole. Image credit: © 2007-2016, Max Planck Institute for Gravitational Physics, Potsdam.
