Physics’ greatest mystery: Michio Kaku explains the God Equation | Big Think

It's no exaggeration to say that the greatest minds of the entire human race have made proposals for this grand final theory of everything," says theoretical physicist Michio Kaku.

This theory, also known as the God Equation, would unify all the basic concepts of physics into one. According to Kaku, the best, most "mathematically consistent" candidate so far is string theory, but there are objections.

"The biggest objection is you can't test it," Kaku explains, "but we're getting closer and closer."
