Is that torturous to you, right?

That's right.

Yeah, gravity torture is a concept from The Expanse.

That's one thing.

All right, here's my admission.

So I haven't read it.

I've seen the series, but I haven't read it.

Fair enough.

Yeah, my bad.

But so gravity, though, is something that I think will be a limiting factor.

But I think there's an even potentially bigger factor that will keep people from being able to move between planets.

And that is microbes, germs, our immune systems.

So what happens to the immune system of a child born on Mars?

They will only ever be exposed to whatever the microorganisms are that we bring with us.

And that's going to be a tiny fraction, right?

I mean, they're going through the same bottleneck.

The microbes are going through the same kind of bottleneck.

peanuts and the wheat and the gluten and the everything yep yep yep exactly and so now you've got a kid who has never been exposed to the vast majority of what we're breathing in right now and and just all the microbes that are surrounding us i don't think they would be able to easily come back to earth uh without a whole lot have you got a name have you got a name for this because this is this is a unique kind of it's not speciation but

I don't know that there's a name for this specifically.

I mean, I think that though this is basically the setup for speciation because what do you do in that situation, right?
