Stephen Hawking Zero Quotations

When one's expectations are reduced to zero, one really appreciates everything one does have

Obviously, because of my disability, I need assistance. But I have always tried to overcome the limitations of my condition and lead as full a life as possible. I have traveled the world, from the Antarctic to zero gravity.

My expectations were reduced to zero when I was 21. Everything since then has been a bonus.

If the total energy of the universe must always remain zero, and it costs energy to create a body, how can a whole universe be created from nothing?

A zero-gravity flight is a first step toward space travel.
