I think I can defend everything that I'm saying.

And I think no one can handle it because nobody actually is motivated to go behind.

If general relativity holds, gentlemen, we're in real trouble.

It's very hard.

Einstein is the problem.

We're four light years away from the nearest star.

So if you think about habitable planetary surfaces, if you could grant science fiction powers to Elon and he could terraform the moon and Mars, we'd have three spheres that we could get to sort of by chemical rockets.

That is not enough diversification for humanity.

It's nowhere close.

So then you have this issue, OK, where do we get the supply of spheres?

The issue is atmosphere.

We're all connected by the same atmosphere.

So you saw that with Chernobyl.

The cloud doesn't stay in Ukraine.

The only place to find new planetary surfaces, if we're not going to make artificial platforms, which is very difficult, is to be able to get very far away very quickly.

And you can sort of do this with something called time dilation.

But if you were to tour a round trip and traveling just under the speed of light, by taking a short jump to the nearest star and back, you'd lose eight years relative to your relatives.

That's not practical.

It's not going to work.

You can't really traverse the cosmos of general relativities in force.
