Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers. I think the human race has no future if it doesn't go into space. I therefore want to encourage public interest in space.

Before we understand science, it is natural to believe that God created the universe. But now science offers a more convincing explanation.

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

The laws of science do not distinguish between the past and the future.

All that my work has shown is that you don't have to say that the way the universe began was the personal whim of God.

We should seek the greatest value of our action.

Philosophers have not kept up with modern developments in science. Particularly physics.
