All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.

I enjoy all forms of music - pop, classical and opera.

What is important is that we have the ability to create.

Don't be disabled in spirit as well as physically.

I think the human race has no future if it doesn't go into space.

Why does the universe go to all the bother of existing?

I have lived with the prospect of an early death for the last 49 years. I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first. I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
