The danger of asteroid or comet impact is one of the best reasons for getting into space ... I'm very fond of quoting my friend Larry Niven: "The din… - Arthur C. Clarke

I wanted to kill myself. I would have done it, too, if I had owned a gun. I was considering the gruesome alternatives — pills, slitting my wrists with a razor blade, jumping off a bridge — when another student called to ask me a detailed question on relativity. There was no way, after fifteen minutes of thinking about Mr. Einstein, that suicide was still a viable option. Divorce, certainly. Celibacy, highly likely. But death was out of the question. I could never have prematurely terminated my love affair with physics.

There may be a moral here. For the life of me I can't find it.

If I may be allowed just three wishes, they would be these. Firstly, I would like to see some evidence of extra-terrestrial life. I have always believed that we are not alone in the universe. But we are still waiting for ETs to call us — or give us some kind of a sign. We have no way of guessing when this might happen — I hope sooner rather than later! Secondly, I would like to see us kick our current addiction to oil, and adopt clean energy sources. ... Climate change has now added a new sense of urgency. Our civilisation depends on energy, but we can't allow oil and coal to slowly bake our planet... The third wish is one closer to home. I've been living in Sri Lanka for 50 years — and half that time, I've been a sad witness to the bitter conflict that divides my adopted country. I dearly wish to see lasting peace established in Sri Lanka as soon as possible.
