In order to achieve a true understanding of string theory, some new idea will be required, and most likely, some break with the concepts on which we've traditionally based physical theory.

The Big Bang theory is the idea that if we go back early enough in the history of the universe - and we can do this, of course, by looking at starlight coming to us from billions of years ago - we will see a very hot and dense period where the universe was much smaller, denser, and hotter.

Some wonder whether some day we will arrive at a theory of everything and run out of new problems to solve - much as the effort to explore the earth ran out of new continents to explore.

Quantum field theory was originally developed for the treatment of electrodynamics, immediately after the completion of quantum mechanics and the discovery of the Dirac equation.

We must not confuse religion with God, or technology with science. Religion stands in relationship to God as technology does in relation to science. Both the conduct of religion and the pursuit of technology are capable of leading mankind into evil; but both can prompt great good.

Once you start to look into the guts of climate change you find that just about every scientific institution in the world is conducting research on the issue.

Is science of any value? I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.

Miz & Morrison, 'The Greatest Tag Team of the 21st Century,' was fun because Miz and I have great comedic chemistry for backstage segments and our Internet show, 'The Dirt Sheet.'
