The Universe in a Nutshell: The Physics of Everything Michio Kaku, Henry Semat Professor of Theoretical Physics at CUNY What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may s...hrink the science of the Big Bang into an equation as small as Einstein's "e=mc^2." Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything. (42:14)
