The Universe Doesn't Allow Perfection.

If We Ever Do Find A Complete Theory Of The Universe, It Would Be A Great Triumph Of Human Reason But It Wouldn't Leave Much For Us To Do. We Need An Intellectual Challenge.

The Development Of Full Artificial Intelligence Could Spell The End Of The Human Race.

I Think The Human Race Doesn't Have A Future If We Don't Go Into Space. We Need To Expand Our Horizons Beyond Planet Earth If We Are To Have A Long-term Future. We Cannot Remain Looking Inward At Ourselves On A Small And Increasingly Polluted And Overcrowded Planet. We Need To Look Outward To The Wider Universe.

While Physics And Mathematics May Tell Us How The Universe Began, They Are Not Much Use In Predicting Human Behavior Because There Are Far Too Many Equations To Solve. I'm No Better Than Anyone Else At Understanding What Makes People Tick, Particularly Women.

For Years, My Early Work With Roger Penrose Seemed To Be A Disaster For Science. It Showed That The Universe Must Have Begun With A Singularity, If Einstein's General Theory Of Relativity Is Correct. That Appeared To Indicate That Science Could Not Predict How The Universe Would Begin.
