What If a Black Hole Deleted the Universe?

[Music] they're massive and extremely dense they rip apart anything and everything that gets close to them we can't see black holes but we know they have the destructive power to wipe everything out of existence this is what F and here's what would happen if a black hole deleted the universe before we get to the part where a black hole erases the universe let's make something clear the universe is a giant supercomputer processing information without information there can be no universe but what is information in physics information is the property of a specific state of a particle I know it sounds confusing here's a simpler way of looking at it this is a carbon atom a bunch of these can be arranged to make a hard diamond but if you change the arrangement of atoms you can get soft graphite the basic building blocks are the same it's information that makes them different in quantum mechanics information is like energy it can't disappear into nothingness so how in the universe can one black hole do the impossible that's the black hole information paradox black holes act like monstrous cosmic trash compactors they squeeze stars planets and unfortunate astronauts who cross the event horizon into a microscopic point so what happens to the information about every particle that a black hole consumes since information can never be destroyed it has to be stored somewhere inside that black hole right our original understanding of black holes assume that everything that disappeared in the black hole stayed in the black hole the moment an object passed the event horizon it got crushed into the density of the black hole the information about it could never be retrieved again that's what we thought before Stephen Hawking introduced Hawking radiation hawking realized that black holes aren't static rather they release their mass and energy back into the universe particle by particle until there's nothing left so does that mean the information within a black hole can somehow escape with the black hole's outgoing radiation not quite the black hole doesn't preserve the information it consumes it chaotically mixes it together with other bits of information making it impossible to recover the information is lost forever if the information can be lost that would mean that black holes can eventually delete the universe forever but there is a possibility that the black hole doesn't delete the information it may be hiding it in a baby universe a small self-contained part of the universe that branched off of ours the information wouldn't technically be lost but we wouldn't be able to interact with it another possibility is that black holes can encode the information according to the holographic principle if you were to get trapped inside a black hole you'd still experience three-dimensional space for us looking at you from the outside you'd appear stretched on the flat surface just like a hologram that would mean that the information paradox is resolved and we don't need to rewrite the laws of physics but we'd have to rethink our understanding of reality the universe could be a three-dimensional image projected off a two-dimensional surface and you may be a hologram on the surface of a black hole and the best part the black hole couldn't delete the universe after all wait how could we be living in a hologram well that's a story for another what if [Music] hey thanks for watching and don't forget to comment write in your what if ideas down below
