We're in 'Jurassic Park' territory. If we go to the zoo in the future, we'll have zoos for extinct animals.

They basically ask their engineers to volunteer some probability figures, then they take the average. This is not science. This is voodoo.

To become a theoretical physicist ... you need to have a passionate love affair with the universe.

The next big accelerator might be the ILC in Japan, a linear collider which might be able to probe the boundaries of string theory. So we physicists have to learn how to engage the public so that taxpayers money is used to explore the nature of the universe.

Our grandkids will lead the lives of the gods of mythology. Zeus could think and move objects around. We'll have that power. Venus had a perfect, timeless body. We'll have that, too. Pegasus was a flying horse. We'll be able to modify life in the future.

I hope we find evidence of dark matter in the lab and in outer space. This would go a long way to proving the correctness of string theory, which is what I do for a living. That is my day job. So string theory is a potentially experimentally verifiable theory.

Growing new organs of the body as they wear out, extending the human lifespan? What's not to like?
