I never stopped loving the deeper sciences, and I read as deeply into lay science as I can.

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.

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.

You need a human story to intersect those points of interest with real stakes on the line, and then things start to be fun, where you can see the ramifications, you see the impact on people's lives of big changes - like taking a man of science, like a surgeon, and robbing him of his understanding of the universe and forcing him into a newer and wider understanding.

I'd wanted to be a writer since I was knee-high. Once I knew that books were written by people and didn't just happen, it was obviously that I would write them, too.

The science fiction I write comes from a pretty deep pool of literature, not just from the reflection of other science fiction films, and I think that gives me somewhat deeper roots.

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.
