We Are Only The Temporary Custodians Of

I Don't Think The Human Race Will Survive The Next Thousand Years, Unless We Spread Into Space. There Are Too Many Accidents That Can Befall Life On A Single Planet. But I'm An Optimist. We Will Reach Out To The Stars.

If I Have Questions About The Universe On My Mind When I Go To Bed, I Can't Turn Off. I Dream Equations All Night.

When I Was First Diagnosed With Als, I Was Given Two Years To Live. Now 45 Years Later, I Am Doing Pretty Well.

What I Have Done Is To Show That It Is Possible For The Way The Universe Began To Be Determined By The Laws Of Science. In That Case, It Would Not Be Necessary To Appeal To God To Decide How The Universe Began. This Doesn't Prove That There Is No God, Only That God Is Not Necessary.

Life Would Be Tragic If It Weren't Funny.
