If you want to move at close to the speed of light, you're going to be encountering bullets along the way because even tiny hydrogen atoms and little particles of dust basically have massive kinetic energy at those speeds.

And so basically you need some kind of shielding.

You have all the cosmic radiation.

It's just like brutal out there.

It's really hard.

And so my thinking is maybe interstellar travel is just extremely hard.

It just might be that you have to go very slowly, potentially, as an example, through space.

So I'm suspicious, basically, of our ability to measure life, and I'm suspicious of the ability to just permeate all of space in the galaxy or across galaxies.

And that's the only way that I can currently see a way around it.

Or they're all just independent.

They're all just like little pockets.

Some of them happen to be close, yeah.

Yeah, I think the question, it's really hard.

I will say, like, for example, for us, we have lots of primitive life forms on Earth next to us.

We have all kinds of ants and everything else, and we share a space with them.

And we are hesitant to impact on them, and we're trying to protect them by default because they are amazing, interesting, dynamical systems that took a long time to evolve, and they are interesting and special.

And I don't know that you want to...

destroy that by default.

And so I like complex dynamical systems that took a lot of time to evolve.

I think
