Bringing the astronaut's nightmare to life so vividly is a remarkable accomplishment but Alfonso and Jonas Cuaron want more than just the adrenaline ride - they're feeding our wonder and inviting us to think deeply about profound questions of existence.

Something my father dearly loved is the scientific method, and it's founded in this element of humility. The idea is that you pursue the truth wherever it goes; you need to evidence, and you can - you see if it's repeatable.

Nick Sagan

For a genre that's about looking to the future, science fiction has sure been looking backwards lately. Nostalgia is what sells best, with readers spending their money on movie tie-in novels and sequels to long-running series.

Nick Sagan

We have not been asking the serious questions about the future of our species, questions sci-fi regularly explores by showing us the best and worst of what could be.

It goes back to the starfish. That's when the light bulb really popped over my head. We'd found one on the beach, and I was struck by what astonishing creatures they are, talking with Dad about how they regenerate.

Human divisions would be child's play for any reasonably competent alien overlord to exploit - check the masterful 'Twilight Zone' episode 'The Monsters Are Due on Maple Street' for an example of how that might play out.

Nick Sagan

Humans having any kind of sporting chance against hostile alien invaders armed with superior technology - Good luck. If they're advanced enough to cross the enormous distances of interstellar space, they're advanced enough to wipe us out without breaking whatever in their physiology passes for a sweat.

I think of 'Shrapnel' as the anti-'Star Trek.'

I've met secular humanists who grew up in evangelical households, for whom 'Cosmos' was their first exposure to a scientific way of viewing the world.

Nick Sagan

'Life in space is impossible,' we're warned, and amidst the hypnotic beauty of these heavens, we become painfully aware of what a hostile environment space is, how unforgiving, how unsympathetic to human desires.

Nick Sagan

My father was not only a planetary scientist and a great popularizer of science, but he thought very deeply about the world. He was a scholar, he studied history. He taught a class in critical thinking, and he was very, very aware of the directions we might go.

Nick Sagan

Dad was a difference maker. He reached out to people. He took them by the awe and wonder we feel over the most important questions we can think to imagine. He pulled them away from blind faith, away from pseudoscience, toward a deeper, richer understanding of the universe.

Nick Sagan

Higher levels of technology allow fewer people to do more damage.

Nick Sagan

Here on Earth, we've found organisms that thrive in environmental conditions we would have once thought uninhabitable. The presence of these extremophiles suggests that life could potentially take hold on worlds other than our own.

Nick Sagan

There is a danger, increasingly, that we're in a post-fact society where it seems my ignorance is as good as your facts.

Nick Sagan

Science is a wonderful way of getting out what's real.

Nick Sagan

Dad was a world-famous astronomer; Mom was the artist who drew the iconic Pioneer plaque.

Nick Sagan

American sci-fi has fallen into the doldrums in part because of the anti-science sentiment that's so prevalent in our culture lately.

Nick Sagan

British and Canadian sci-fi strikes me as more forward-looking than its American counterpart, as evidenced by the success of Iain M. Banks, Charlie Stross, Robert Charles Wilson, and Cory Doctorow.

Nick Sagan

Beyond 'Contact,' I think there's something compelling about 'District 9.'

Nick Sagan

We're so bitterly divided these days, the appearance of a true 'other' might be the best chance of bringing us all together.
