The first colony on Mars is not going to be built by a private company. How are you going to make money? You're not.

I think if everyone had the luxury to pursue a life of exactly what they love, we would all be ranked as visionaries and brilliant.

No one is dumb who is curious.

The theory of evolution, like the theory of gravity, is a scientific fact.
