What if singularities do not exist?

PBS Space Time can’t be upvoted enough. It’s been delivering fantastic videos for years.

I have become completely convinced that there just isn’t any space inside a black hole. I can’t say I have a good reason for the conviction. But if you see how the maximum amount of information in a black hole grows with the surface area of the hole, not the volume, it seems to me that whatever process is responsible for creating spacetime simply breaks down at the event horizon. So space suddenly becomes very sparse or even non-existent inside.

An aspect of this belief is that matter/energy doesn’t just warp spacetime, it’s creating it. I feel like this could explain why at large distances, galaxies are moving away from each other (“dark energy”).. if space is sort of piling up in those empty areas it would effectively push galaxies away from each other.

I’m a total amateur so I’m probably wrong.

I suspect Wolfram is on the right track but he seems to be approaching from a similar angle as string theory: trying to craft a perfect beautiful theory from the ground up.. that ends up being able to describe an infinite number of possible universes.

I think if some of the ideas he was exploring was developed in a more pragmatic way, by trying to graft some aspects of it onto existing theories, in what will probably be a much uglier and messier theory, we might make some progress.

I thought it was well understood that the most likely thing is just different physics we can't measure or predict? And in a quantum-mechanics type agnosticism we decided things that aren't measurable aren't worth trying to understand.
