The politics is far harder than the science. And even if we accept the science we have a big issue of how to deal with it.

In future, children won't perceive the stars as mere twinkling points of light: they'll learn that each is a 'Sun', orbited by planets fully as interesting as those in our Solar system.

Absence of evidence is not evidence of absence.

It will not be humans who watch the sun's demise, six billion years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.

I think a few hundred years from now we'll start having the 'posthuman' era of different species.

It's better to read first rate science fiction than second rate science-it's a lot more fun, and no more likely to be wrong.

We need to broaden our sympathies both in space and time - and perceive ourselves as part of a long heritage, and stewards for an immense future.

Science is a part of culture. Indeed, it is the only truly global culture because protons and proteins are the same all over the world, and it's the one culture we can all share.

I hope that by 2050 the entire solar system will have been explored and mapped by flotillas of tiny robotic craft.

I'm not myself religious but have no wish to insult or denigrate those who are.

Crucial to science education is hands-on involvement: showing, not just telling; real experiments and field trips and not just "virtual reality".

Success for me its to raise happy, healthy human beings.

We have the greatest hospitals, doctors, and medical technology in the world - we need to make them accessible to every American.

I have a certain energy on screen, and it's either needed or it's definitely not needed. I know that I can stick out like a sore thumb, and there are some women I'm not ready to play.

With a Socialist government, there will not be a national surplus whilst there continues to be inequality.

There is nothing more enticing, disenchanting, and enslaving than the life at sea.

I love to make fun of fashion because it is just so silly.

Mistakes are about getting the blessing in the lesson and the lesson in the blessing.

I don't play too much into the color game, because I don't want to be the best African American quarterback, I want to be the best quarterback.

From the time God saved me at 21 years old, I've always been fascinated by the parables of Jesus.
