To boldly go where no one has gone before

I would rather be right than rigorous.

If time travel is possible, where are the tourists from the future?

It's clearly possible for a something to acquire higher intelligence than its ancestors: we evolved to be smarter than our ape-like ancestors, and Einstein was smarter than his parents.

I have experimental evidence that time travel is not possible.

If it [the universe] was expanding fairly slowly, the force of gravity would cause it eventually to stop expanding and then to start contracting. However, if it was expanding at more than a certain critical rate, gravity would never be strong enough to stop it, and the universe would continue to expand forever.

I don't want to write an autobiography because I would become public property with no privacy left.
