Good morning, everybody. Sifan Maloney for Free Domain. Hope you doing well. Great, great questions from

freedomain.locals.com. I hope you would join the community. So somebody has asked, after listening

to you for a decade, you've done an excellent job of covering most everything I could ever think of.

The few things that I might ask, I just use your basic principles and the answer is there.

Not my basic principle, so I appreciate the thought.

We'd love to get on a time machine and see what impacts your ideas we'll have on the future.

Right.

I mean, you know, time travel is one of these funny things.

Okay, so the only way that you can time travel that we know of, and really it's the only,

you can cryogenically freeze yourself

and so on, but you can't go forward and you can't go back, can't go back. And you can't get into

a little thing, like you can't get into a little booth and then time travel. You know, that's,

that's just lazy writing for writers who want to break reality. Because the Earth is in constant motion, you know, it's,

I mean, not only rotating, but it's corkscrewing around the sun, which itself is rotating

around the galaxy, which itself is rushing through space. So even if you went forward in time,

say, like where you were, you changed whatever time, let's say you were able to go back 10
