  • Black holes are scary things. But they also might reveal the true nature of the universe to us.

    A bug crawls into your hardcover book. You immediately panic, and slam the book closed, crushing the bug in the process. When you reopen the book, you see it there on the page, completely flattened. Not totally two-dimensional any more than the letters on the page, but as flat as flat can be nonetheless.While you observe the flattened insect, a large spider crawls onto the same spot in your book. Jumping from your seat, you slam the book closed again. Upon inspecting the page you left off on, the insect is completely obscured by the spider. The lump appears flat as can be, but has grown in mass now that both bugs are imprinted into it. The "information" of the bugs is all still there, but the insect's information is irretrievable until you get past the spider's information. Could you get to the information without removing the spider on top?Does the surface really tell the whole story? For all intents and purposes, I doubt it.There are two scenarios I could see for all information within the black hole being visible to an external viewer:1) All information really is encoded on the surface of the black hole. Information is still held in the original particles, but compressed. Therefore, the black hole would have to be hollow, allowing all molecules to be on the surface, facing the outside. The "information" would truly be encoded in its entirety on a flat surface. Given the great gravity of black holes, I doubt this.2) The particles are piled on top of each other, like the bugs in my previous example. For their information to reach the surface of the black hole and escape, Hawking Radiation emitted must escape to the surface of the black hole, and subsequently escape the event horizon, even if the original particles are buried deep.Alternatively, Hawking radiation may only emanate from the outermost layer of the black hole, which means the "information" is not accessible without digging into the black hole. Very similar to the bug example if the viewer cannot use penetrating EM waves.I'm curious if anyone has any thoughts or facts to shed more light on this. If that anyone is you, please comment below and enlighten me :)Disclaimer: I suck at physics :P

    black hole? A hole in what exactly? the sky? You dont know its a hole. Its a stupid idea a hole. There are no holes. This is a guess at best a lie at worst. Its definitely not science. Its science fiction.

    Humans know almost sweet fuck all of what REALLY happens inside a black hole, or even what they really are, or do. it might take thousands of yrs before even know half of the truth. All this is theories. but when we finally do. it will change EVERYTHING, literally.
