In the future we'll be able to mentally contact anybody we want, see whatever image we want. And when we don't like it, we'll just turn it off.

I agree, along with Carl Sagan, that we should eventually become a two planet species. Life is too precious to place on a single planet.

A soul might very well exist, but we, as physicists, try to measure and quantify everything. So far, no one has been able to create an experiment to do this for the soul. Efforts have been made to weigh the body after death, but each time we find no evidence of a soul. So a soul may very well exist, but it is not a testable theory.

It's very dangerous to put astronauts on a moon base where there's radiation, solar flares and micro meteorites. It'd be much better to put robots on the moon and have them mentally connected to astronauts on the Earth.

We need an enduring, robust theory of education. Now, it seems education careens from one fad to another and often back again. I think that with better education and students willing to put in the 10,000-hours to become expert, we could develop better science professionals, even theoretical physicists.

What do oil company executives, vampires and NASA bureaucrats all have in common? They fear solar energy.

All kids are born geniuses, but are crushed by society.
