Physics Problems for the New Millennium

Listen / Download

Sometimes it seems physicists have answered all the big questions already. The results are tangible — man has been to the moon and split the atom, and split the atom smaller and smaller.

But there are still questions to answer in the search for physics’s Holy Grail — The General Theory of Everything. Even as we speak, scientists are trying to figure out the answers to these questions: Can you calculate the dimensionless parameters of the physical universe? What is the lifetime of the proton? Is nature supersymmetric? Is the cosmological constant really constant?

In their search physicists are refining the language of mathematics and extending the language of words. How long is a ball of superstring? Physics Questions for the New Millennium, on the Connection.
