A theory of everything would be tying general relativity with quantum physics. Michio Kaku believes we are close.
String theorist Michio Kaku: a ‘theory of everything’ is within our grasp
Read the rest of the article at the link.Michio Kaku is a professor of theoretical physics at City College, New York, a proponent of string theory but also a well-known populariser of science, with multiple TV appearances and several bestselling books behind him. His latest book, The God Equation, is a clear and accessible examination of the quest to combine Einstein’s general relativity with quantum theory to create an all-encompassing “theory of everything” about the nature of the universe.
How close do you believe science is to accomplishing a theory of everything?
Well, I think we actually have the theory but not in its final form. It hasn’t been tested yet and Nobel prize winners have taken opposite points of view concerning something called string theory. I’m the co-founder of string field theory, which is one of the main branches of string theory, so I have some “skin in the game”. I try to be fair and balanced. I think we’re on the verge of a new era. New experiments are being done to detect deviations from the Standard Model. Plus, we have the mystery of dark matter. Any of these unexplored areas could give a clue as to the theory of everything.
String theory involves a great deal of theoretical physics, fiendish mathematics and mind-boggling abstraction. Do you think the general public is able to grasp the details of this debate?
I think the public is curious as to what the consequences of this theory could be. The universe in some sense is like a chess game and for 2,000 years we’ve been trying to figure out how the pawns move. And now we’re beginning to understand how the queen moves and how you get a checkmate. The destiny of science is to become like grandmasters, to solve this puzzle that we call the universe. There are outstanding questions that the public wants to have answers for. For example, time travel, other dimensions, wormholes. What happened before the big bang? What’s on the other side of a black hole? None of these questions can be answered within the framework of Einstein’s theory. You have to go beyond Einstein into the quantum theory.
How much, do you think, would Isaac Newton understand of your book?
I think he would appreciate it.
