If you ask almost any of them, 'Do you stand behind your theory? Is this the answer?' I think almost everyone would say, 'No, no, no. I'm just trying to expand the range of possibilities.' We really don't know what's going on.

For almost a century, the Universe has been known to be expanding as a consequence of the Big Bang about 14 billion years ago. However, the discovery that this expansion is accelerating is astounding. If the expansion will continue to speed up, the Universe will end in ice.

My recurring nightmare is that someday I will be faced with a panel: Franklin Roosevelt, John Kennedy and Lyndon Johnson all of whom will be telling me everything I got wrong about them. I know that Johnson's out there saying, 'Why is it that what you wrote about the Kennedys is twice as long as the book you wrote about me?'

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
