The laws of science, as we know them at present, contain many fundamental numbers, like the size of the electric charge of the electron and the ratio of the masses of the proton and the electron .... The remarkable fact is that the values of these numbers seem to have been finely adjusted to make possible the development of life.

So next time someone complains that you have made a mistake, tell him that may be a good thing. Because without imperfection, neither you nor I would exist.

We are only the temporary custodians of the particles which we are made of. They will go on to lead a future existence in the enormous universe that made them

So when people ask me if I believe God created the universe, I tell them that the question itself makes no sense. Time didn't exist before the Big Bang, so there is no time for God to make the universe in. It's like asking for directions to the edge of the earth; the earth is a sphere, it doesn't have an edge, so looking for it is a futile exercise.

Without imperfection, you or I would not exist.

To boldly go where no one has gone before

Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.
