Is the human race a universal constructor?

Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things.

I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.

Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.

Every problem that is interesting is also soluble.

Our best theories are not only truer than common sense, they make more sense than common sense...

If you reject the infinite, you are stuck with the finite, and the finite is parochial... the best explanation of anything eventually involves universality, and therefore infinity. The reach of explanations cannot be limited by fiat.
