Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book.

I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.

It might be a bloody cheek. But so what? It goes on all the time. Chefs travel the world looking for dishes and try to imitate them in their own menus. That's how good cooking spreads - it's what food is all about. Frankly, in my view, it doesn't matter a damn.

With all the stuff that's going on in the world - after I watch the news, read the news, and listen to my podcasts, at the end of the day, am I really going to watch an episode of murder and time travel?

I take one day at a time. I am not someone to define my goals.
