I like to say that while antimatter may seem strange, it is strange in the sense that Belgians are strange. They are not really strange; it is just that one rarely meets them.

Science is not just there for technology. It's part of what addressing who you are in the universe and understanding your place in the cosmos. Good art, good literature, good music - all of that is for that and science is a part of it.

Metaphysical speculation is independent of the physical validity of the Big Bang itself and is irrelevant to our understanding of it.

Celebrate our brief moment in the sun

In 5 billion years, the expansion of the universe will have progressed to the point where all other galaxies will have receded beyond detection. Indeed, they will be receding faster than the speed of light, so detection will be impossible. Future civilizations will discover science and all its laws, and never know about other galaxies or the cosmic background radiation. They will inevitably come to the wrong conclusion about the universe......We live in a special time, the only time, where we can observationally verify that we live in a special time.

The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis.

Most people don't base their morality on religion in spite what they say. If you ask people, "If you didn't believe in God, would you go out and kill your neighbour?" Most people will say, "No".
