Like in some recognizable, meaningful way.
Right.
And what I would say is I think it will happen much faster than what we would expect based on what we normally are used to here on Earth.
And it boils down to this.
So, you know, we've already talked about how being on Mars is going to make people different, right?
Psychologically different, genetically different, culturally different, all of those things.
As long as you have people who are moving back and forth between Earth and Mars and able to
travel freely between them and basically able to you know able to have sex able to have children able to reproduce so if you can kind of move between those environments that will kind of reduce the differences between those populations right like you're as long as people are exchanging genes you don't get speciation happening very easily so um so then the question becomes like well
Is that going to be the case?
Will it be easy for people to move back and forth between Earth and Mars?
And I don't think it will be.
I think it will be much harder for people to move back and forth between planets than we maybe have appreciated.
And specifically, I mean like people born on Mars.
I think even as soon as the first generation of people born on Mars โ
will potentially have a great difficulty with coming back to Earth.
For one thing, it's the gravity that we've talked about, right?
A child born in a one-third gravity environment is unlikely to build a skeleton that is strong enough to be able to tolerate Earth gravity.
And this is, we've been talking about science fiction, right?
So like this shows up in, you know, I don't know if you watched The Expanse or read the series, but it's like that's a theme that comes up is like, you know, the idea that if you're from a lower gravity environment,
high G is, you know, going to be painful if not.
