                                                        There's actually a theory about where energy goes when it meets the singularity. Many people believe when it happens, a new universe is born from said singularity. The first law of thermodynamics says that energy can neither be created or destroyed. It can only be transferred. This is where black holes come into the mix. If lets say, a star goes inside of a black hole, the energy isn't destroyed. It could be possible that the energy from said star is transferred throughout the singularity to create a new universe (a big bang) cause the energy _has_ to go somewhere. But the question is, if all black holes are the building blocks of every universe created, then what universe made the first black hole, and what black hole created the first universe? The only reason we can come up with is that "time" never started or ended. we perceive time as something that can be fundamental outside our universe. We think time is a relative thing that had a "start" to everything. Then you start to think "But what happened before the start of everything?". but in reality it's possible time never really existed therefore there was no "start" or "end". Sure, there is ends to all universes (like the heat death, or big crunch), but the black holes themselves have already created billions of more universes, with the process keep going on and on with no end. But you could say that "where was the energy created from if energy can't be created or destroyed" it's possible that the energy could've been formed by the big bang, which is theoretically created by a singularity of the black hole. But then you could say, "where was the energy from the singularity from?" and like I said, it could be from another universe. there could be an endless loop of energy being transferred throughout infinite universes, which all of them could be parallel universes (universes that are alternate from ours). Think about it, if there could be an infinite amount of universes it means that almost every universe can be different by the most unnoticeable changes. So in conclusion, energy is transferred throughout infinite universes that had no start or end to anything. Energy has always been here and it will never leave. Time had no start or end, and black holes are the reason why everything has become the way it is now. And all of that has lead up to this point where you just wasted like 2 minutes reading this entire fucking documentary of a paragraph.

                                                        So yeah, if you wanna debunk some stupid shit I might have mentioned in this theory, please tell me. I hope this enlightens some people to understand the concept of the space we're living in. Just in the name of curiosity and theories that keep us from questioning our existence.

It is against fundemantal thermodynamics. Media star Hawking was pushed this idea unnecessarily too far turn it into border line pseudoscience.

                                                                        Kurzgesagt gets something very important wrong here. A black hole doesn't store more information than anything else. Just for its size. Not for its mass. In fact, there is no way to cram more information into a smaller size than a black hole. BUT, it is very EASY to have more information than a black hole contains, for a given amount of mass.

                                                                        • medexamtoolsdotcom

How do I know it can be created? Well add up the surface areas of the event horizons of 2 black holes that merge before and after. There's a LOT more information after.

                                                                                We are probably inside a black hole.
                                                                                Think about it, if the outer perimeter is constantly expanding FTL, at an accelerating pace, and we cannot see outside, is it not a possibility that it is an event horizon we are seeing from the inside?
                                                                                To us, the universe outside is invisible, and possibly nonsensical, spacetime that is folded in a way that allows the outer universal space to function, but seems to defy the laws of physics to those on the other side of the phase line.
                                                                                Where else do we see a similar phenomenon, but in reverse?
                                                                                A blackhole that eats up all local spacetime, "faster" than the speed of light.
                                                                                Just a matter of reference frame.
                                                                                Perhaps it's all just universes/blackhole simultaneously devouring each other, like the celestial serpent that is eating it's own tail, with a primordial, repetitive cycle of big bangs and readsorbtion.
                                                                                Each new cycle is different because of the free will of some of the contents of the interior.
                                                                                This means overthrowing elites is not just the right course of action, it is destiny, God doesn't want the same story repeated as infinitum.
