Far from being accidental details, the properties of nature's basic building blocks are deeply entwined with the fabric of space and time.

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

The bottom line is that time travel is allowed by the laws of physics.

If the theory turns out to be right, that will be tremendously thick and tasty icing on the cake.

All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.

Understanding requires insight. Insight must be anchored.

I believe we owe our young an education that captures the exhilarating drama of science.
