Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang. However, it’s plausible that what we see from inside our Universe is simply the result of being inside a black hole that formed from some parent Universe. If the black holes that form in our cosmos give birth to baby Universes, perhaps we arose from the formation of a black hole ourselves.
I mean, yes I’m assuming they follow the laws of physics. To my knowledge everything about them that we actually can observe does actually follow the laws of physics (including things like time dilation), and we can use what we do know to form a pretty solid hypothesis about what we don’t.
I mean, I could argue that they’re actually c’thulu eggs, and you can’t prove me wrong because we can’t look inside! …but there’s also no evidence to support that. Drawing conclusions about reality based on science fiction is silly. We ofc don’t know everything about the universe, but we should stick with what real evidence actually supports.
Yeah I agree that we shouldn’t try to contradict the evidence we have without a good hypothesis to back it up, I just feel like we’re still at a stage where the mathematics give us an idea of what might be possible, but that is seriously constrained by our limited understanding of what happens at these grand scales. Without letting your mind wander to the possibilities of what could be, we would never take the time to look beyond what we know. I’m just trying to say that our knowledge of the subject is still greatly limited, and this idea can’t be ruled out completely until we know more. In the meantime, what if someone did seriously explore the notion? Perhaps they’ll find proof that shows it can’t be possible, but perhaps they might also stumble upon a idea even more fantastic.
That’s what I’m saying though - the hypothesis that we exist in a black hole does contradict the evidence currently available. Or at least I think it does - I opened the contractions initially as a question because this isn’t my area of expertise. I’ve had a few relevant classes, and have a casual interest in the topic, so I think I have a pretty solid foundation at least; but ultimately I’m just a medic, so I was kinda hoping someone with a more dedicated background would chime in.
There’s a LOT of BS surrounding the topic of black holes - and understandably so. They’re intriguing as hell, so it’s no wonder that they’re so often the object of artistic freedom. But all’s fine and well to proclaim that they’re some kind of portal, or mini universe, or cleverly disguised alien spacecraft, or even a sentient creature… in the context of science fiction. But to say any of those about black holes IRL should come with supporting evidence, especially if some aspect of the proposal clashes with our current interpretation of what we can either directly observe or indirectly postulate.
