Singularity
If we rewind our clocks to roughly 13.8 billion years ago, we arrive at a moment when the universe is infinitely dense and hot– a singularity.
Big Bang
At the singularity, where time, space and matter seem to begin, the laws of physics break down and we arrive at what scientists call the “beginning of everything”, or the Big Bang.
Black holes
The Big Bang is a widely accepted theory about the origins of the universe. However, scientists have also considered alternatives, including: Did our cosmos emerge from a black hole?
Size of the universe
Mathematically, if all the matter in our universe were to be condensed down to form a hypothetical black hole, it would be the same size as our observable universe.
Parent universe
A group of scientists explored the idea that the universe may not have begun at a singularity, but rather emerged from the collapse of a massive cloud of matter in another universe.
Formation of black hole
When massive stars die and collapse under their own gravity, it leads to the formation of a black hole.
Bounce
Under the right conditions, the collapse of a cloud of matter wouldn’t result in a singularity rather it would bounce and begin expanding again. This bounce mimics the Big Bang.
Similar conditions
In essence, the mathematical conclusion that the scientists arrived at indicates that the conditions inside a black hole would be very similar to our universe.
Laws of physics
This study, in particular, stands out because it reaches the conclusion without breaking any known laws of physics, unlike its predecessor theories.
Big Bang didn’t happen?
This theory leads to some startling conclusions, including the most obvious one that the Big Bang theory is wrong.
Multiverse
Second, it would also mean, the black holes in our universe have universes inside of them that we cannot observe, pointing to the theory of the multiverse.
