I think the greatest danger of the promise of space travel is that it can lead us to be cavalier about the world we live on, if we assume we can find or make more worlds. I think in our lifetimes we surely will not, probably in the lifetimes of our great-great-grand-descendants we will not.

I try to keep up, and the scientific perspective is always part of my creative approach.

Space and spacecraft and zero gravity and so forth are very difficult to render.

Most of my life, I thought that I would end up a novelist. But then, in New York City, after college, I started a company with a college friend where we made documentary video for museums. In that capacity, I shot, directed, edited and began to learn the vocabulary of film.

Real vectoring in space, real orbital mechanics, is very counterintuitive, very strange, and very hard to render. It's expensive, and there's a learning curve. Some of it is about raising audience literacy to the point where they understand that.

Once you've written a good script, it will get made or not get made, according to variables you cannot control, like stars getting interested, and the superstitions in Hollywood rising or falling around what is over and done with versus what's in.

I will never probably have the mathematical foundation to truly understand what string theorists are talking about, but it feels good, just for its own sake, to get as close to an understanding as you can.
