Never put off the work till tomorrow what you can put off today.

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.

Disorder increases with time because we measure time in the direction in which disorder increases.

Science can explain the universe without the need for a Creator.

I think those who have a terminal illness and are in great pain should have the right to choose to end their own life, and those that help them should be free from prosecution.

Because imaginary time behaves like another direction in space, histories in imaginary time can be closed surfaces, like the surface of the Earth, with no [existential] beginning or end.

The "Powers That Be" are not smart enough to engineer Armageddon, but they may yet be stupid enough. If governments are involved in covering up the knowledge of aliens, then they are doing a much better job of it than they seem to do at anything else.
