I Like Physics, But I Love Cartoons.

I Do Not Believe In A Personal God.

I Want To Know Why The Universe Exists, Why There Is Something Greater Than Nothing.

We Have Made Remarkable Progress In The Last Hundred Years, But If We Want To Continue, Our Future Is In Space.

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.
