Unexplainable · Are we all living in an enormous black hole? · 6 Jul 2026 podcast

So for example, my astronomer friends are very, very good at calculating what the total mass of the observable universe is.

I put it into the equation that says how tightly I would have to pack that.

You'd think it's something like the size of a galaxy or something like that, right?

But it turns out that the amount of stuff in the universe, the observable universe, would need to be packed into a volume that is already larger than the observable universe.

That's weird.

If you say that's weird, it's because it is.

When I first came across this calculation, I think just like any other physicist, the first time you come across this calculation, you think, well, that can't be right.

And so you go and start looking at it yourself and you do it yourself and it's absolutely true.

So you start to think, okay, well, maybe my astronomer friends, they made an error.

Maybe the mass of the universe is not really what they think it is.

Maybe they got it off by half, right?

I mean, that's a huge error.

So maybe the total mass of the observable universe is only half of what it is.

But it turns out you would still need to pack the entire universe into a volume that's already larger than what it is itself.

So then you take this to its logical conclusion and you might ask the question, is our entire observable universe inside an enormous black hole?

And that's a bit disquieting.

Completely aware.

And so at first that doesn't make much sense because, you know, again, I thought black holes were these enormous objects that are kind of voraciously sucking in things and spaghettification and stretching everything.

Like if I look at the moon, it's not being voraciously sucked and pulled in one direction, right?

Or being spaghettified, right?
