    Did the universe emerge from a black hole?

    Was that one also conceived that way?

    Would a multiverse be like a Russian doll?

    Does it explain why time runs in one direction and dark energy exists?

    The universe is full of black holes from micro ones to super massive ones.
    So could this be the best explanation for why the universe bothers to exist and why it's destroying itself in a heat death?

    How do we know if there are micro black holes? Doesn't evaporation eliminate their existence, or are they just now becoming micro after a long time at larger mass?

    Everything here seems oriented to black holes. Perhaps the universe we "see", and live in, is the biggest one, since no one really knows what is going on inside of one (Russian doll?).

    Heat death could be an illusion if the innards of black holes alters all of our concepts of matter, space and time.

    Most importantly, how could any of this really be proven?! Lots of questions, are there any real answers?

    Perhaps we need a new science - "the science of what's happening now". Updates later...........

    It might depend on the detection of extra dimensions if we could prove that short lived microscopic black holes exist.

    Another way of looking at it - what if the stars turned off?
    We are here because the stars are here.
    If a black hole has not generated stars then life as we understand it could not exist.

    It shouldn't mean that any possible universe will have stars.
    All it potentially needs is some form of mathematics, an idea by Max Tegmark.

    Did a black hole cause the Tunguska event?
    Or was it an asteroid, a meteorite, a comet, an antimatter meteor, a nuclear test, or some other force?
    Nobody knows for sure.

    Could the universe be a quantum computer within a black hole / box?

    We need to know what goes on inside a BH.

    Spherical "high-Z" particles found in tree resins from the time of the blast are a pretty solid indication of a bolide causing the Tunguska event.*

    Some speculations about the origin of the Tunguska and other similar events like the extinction of the dinosaurs from 'Dark Matter and the Dinosaurs' by Lisa Randall:

    No one knows why an object like a comet or meteorite be perturbed from its stable orbit and explode in the Earth's atmosphere.
    Did the Sun's passage through the galaxy encounter dark matter which dislodged the object and sent it hurtling towards Earth?
    Dark matter might have been relevant to the formation of black holes.

    There is no escape from all these ideas about black holes!

    Dark matter itself could be primordial black holes which formed by direct collapse in the "final" stages of the BB.

    Sounded a bit too much to buy into, and then found reports of how SMBHs could have formed by "direct collapse" from the high density of matter forming in the final stages of the BB - no need for a stellar intermediate. Such "primordial" BHs (PBHs) could actually have formed at any mass, and there are no physical principles which eliminate this hypothesis. There are visible galaxies with AGNs which appear much earlier than predicted by the pop III route.

    Recent BH mergers, with some BHs approaching 100 SMs, could suggest evidence for PBHs.
