Apparently, a great deal of dark, unseen material exists, whose gravitational pull is responsible for the motions of the stars and galaxies that we see.

We are just strings of quarks living in a suburb of the local density maximum of the universe.

Once upon a time there was no Time.

We can never know the origins of the universe. The deepest secrets are the ones that keep themselves.
