A unified theory would put us at the doorstep of a vast universe of things that we could finally explore with precision.

It's hard to imagine anything more interesting than learning how we're woven into the enormous tapestry of existence. Where did our universe come from? How special is our world, and how special are we? We allocate tens of billions of dollars annually to NASA, NSF and academia in search of the answers.

And the continuity of our science has not been affected by all these turbulent happenings, as the older theories have always been included as limiting cases in the new ones.

If we do discover a complete theory, it should be in time understandable in broad principle by everyone. Then we shall all, philosophers, scientists, and just ordinary people be able to take part in the discussion of why we and the universe exist.

One of the great challenges of modern cosmology is to discover what the geometry of the universe really is.

Cosmology is a rapidly advancing field.

Observe constantly that all things take place by change, and accustom thyself to consider that the nature of the Universe loves nothing so much as to change the things which are, and to make new things like them.

When we see what the universe has to show us, we can go no further.

The idea that there could be other universes out there is really one that stretches the mind in a great way.

I think the universe is just so big that there has to be something else out there.
