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’ve seen this pop up a few times, but there are a couple big issues that pop up right out the gate.
Space is constantly expanding with no center. If we’re in a back hole, we and everything else in here are cruising toward the singularity. And if we’re in a black hole, we’re already passed the event horizon, the point at which gravity is so strong that even light can’t escape; and as we progress toward the singularity, that force becomes exponentially stronger… so light from one point inside the black hole would have very limited potential to cross paths with another point… so how is it light from stars is actually making it to us / for the few stars we’re actually in the line of fire for it’s light - if that’s even possible inside the event horizon - shouldn’t the night sky only have a narrow region of visible stars; and shouldn’t they appear distorted as s all hell?

Anton Petrov just put out a video with a similar topic: youtu.be/l4C6Ll6sIQU?si=ac9K5RKYrbFmyapj
He is an awesome science youtuber and does a great job of explaining research on these kinds of topics.
I haven’t watched it yet but will soon. (It popped up on my feed today and remembered it, just for you!)

I really like his content, but his way of speaking (can’t even say what exactly) is somehow perfect for my brain to completely tune out. I have to really focus on it to actually mentally process it.

Yeah, I use his channel to fall asleep sometimes.

Agreed. He’s very monotone and I don’t think his mic is very good. I like the content, not trying to tear someone down but he’s not a small channel anymore. Wish the production value was a bit higher to engage us more. I want to watch every video but I only watch the ones that I really want to know more about, for this reason.
