    The problem with imagining yourself falling in a black hole is that you can not experience time "while" in a black hole that is in the same universe as when you left: Metabolic rates involve electrons, and the nature of the black hole itself is that it naturally strips the electrons off of the nucleus of atoms by pushing the atomic centers closer together, the clouds of electrons being forced away from their nucleus by the crowding of other atom nuclei is the same problem with everything entering the influence of the event horizon; there is a very real shedding of electrons that many physicists say must "spaghettify" the matter crossing such a horizon because some scientist got the idea that every atom must go through some incredibly small hole it can't fit through.
    This is completely false.
    It supposes that space gets too tight for a single atomic nuclei to go through the center of the black hole. This is a misinterpretation of the local environment of the black hole: everyone assumes that the cloud of electrons around a black hole, in the accretion disk means that the metabolism of the item (it's literal clock of an electron circling around the nuclei acts as a perpetual oscillation machine that links us to our atomic nuclei into a "time" in space.) going into the black hole must be the same as the "metabolic clock" of the atoms you use to see with your eyes.
    This is where your perspective is patently false when compared to the rate of time perceived by the "victim" of the black hole that is falling inside.
    To them the horizon would slip above their view and stop with nothing in view, and time would return with the view of the universe coming back into place around you as space started to fall inside as well, allowing you to perceive time only after the electrons have started to permeate into a black hole's environment, and that is only after the black hole has evaporated; literally keeping the atoms from experience space or time for the entire existence of the back hole itself.
    This removed the atoms from the time of the old universe because the energy that made up the electrons of the atoms in the heart of the black hole had to wait for the black hole to evaporate again due to Hawking radiation, for them to start having a regular existence compared to the previous space time on the other side of the black hole's event horizon.
    We get separated by time, and we unfold back into regular space in an almost inconceivably long period of duration expected of the eventual vacuum death of the universe, which is the half life of every stable molecule in the black hole. That is the time passed when the nuclei escapes in a white hole to return to the fabric of space once again released to meet up with their counterpart electrons. According to the second law of thermodynamics, energy can not be created or destroyed, merely transmuted into the other and back again.
    Essentially time is turned into a solid when you are in a black hole, and then it is returned back into a fluid when you return to "regular" space. That solid chunk of time that is an eternity until the black hole turns into a white hole is NOT experienced by any atom separated from it's electron.
    That nuclei was transformed into a non-time experiencing oscillation that forced the molecules to start vibrating to when it crossed the event horizon: that is the event, matter synchronizing in oscillation between the universe, and the compacted nuclei of all the matter that fell into it before then.
    This suggests that time will not be experienced UNTIL that black hole evaporates because the nuclei is synchronized to a different frequency, that of the black hole that absorbed the matter in the first place.

    I am a bachelor of science and would like to fight this thesis: If you burn a piece of paper, the information is lost! You may store the atom soup in a bag. But unless you prior to this have stored all atom positions (on a hard drive?). You will never be able to arrange the paper back again.
    Why would a VERY destructive black hole store this delicate information?

    Reminder that none black have ever been direclty observed but just deduced so maybe even what science thinks of them now is wrong on a fundamental level, by that I mean we can never have a definitive definition about reality just a humanly digestible rationalization of it.

    Why do we have to be a 3D image stored on a 2D surface? Why can't we be a 4D image stored on a 3D surface? Wouldn't that make more sense? And couldn't that mean that the 4D form of the surface of our universe exists in a 5D universe, moving up as far as possible until any higher dimensions collapse in on themselves because they are too complex to exist?

    If the universe was a black hole then the Big Crunch theory would be the primary theory due to Hawking radiation and dark energy/the expansion of the universe is just the black hole gaining mass this also explains what truly happens with the mass black holes swallow and makes the fact that the universe just appeared out of nowhere much more believable

    Would this idea of information also allow us to theoretically foresee the future as opposed to see the past? My idea here is that the whole universe is basically just a huge chain reaction. And usually one can determine the outcome of a reaction if one has every parameter (except in quantum physics of course). If I release a glass thats in my hand for example I can already tell the future by knowing that the reaction that follows will shatter the glass.

    String thermory solved: If everything that gets sucked in to a black hole does that in a tiny piece at the time, so it becomes a long string of the absolute tinyest buildingblocks of our universe. We would kind of have a 1D string of information stored in layers upon layers... and in this case, black holes just as they say in the video is a huge storage device. And we consist of long strings more or less. The known universe is the program running. Black holes are the backup disk. just an idéa :P /someone who knows nothing about this stuff.
