We live in the most probable of all possible worlds.

Exploration by real people inspires us.

Some people would claim that things like love, joy and beauty belong to a different category from science and can't be described in scientific terms, but I think they can now be explained by the theory of evolution.

If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.

We only have to look at ourselves to see how intelligent life might develop into something we wouldnt want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.

God not only plays dice, he throws them in the corner where you can't see them.

Over a very small number of rolls of the dice, the uncertainty principle is very important.
