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.

Anton Petrov just put out a video with a similar topic: https://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. No shade.

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.

I used to think this idea was kinda silly and based on flimsy and handwavey justification, but then I saw a colloquium by a famous black hole physicist on it. Now I REALLY think this idea is silly and made up!

Followuo question. Is our universe perhaps a former seed universe contained in another, the same way black holes are within our current universe?

And is it universes all the way down?

And at the bottom, a turtle

how could this be 'plausible', it makes no sense based on how we currently understand black holes.

One thought that always fascinated me was the idea that maybe our universe does appear to outsiders ..... but it only appears as a sudden momentary flash. We see billions of years, they barely notice a spark.
