Physics’ greatest mystery: Michio Kaku explains the God Equation

Can one equation unite all of physics?

  • "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."

  • Gamers often report losing track of time while playing, but virtual reality headsets amplify this effect.
  • Test subjects using headsets were off by an average 28.5 percent more than those using a typical screen.
  • A potential application of this finding is using it to help people endure difficult medical procedures, such as chemotherapy.

  • Sci-fi movies and books love wormholes—how else can we hope to travel through interstellar distances?
  • But wormholes are notoriously unstable; it's hard to keep them open or make them big enough.
  • Two new papers offer some hope in solving both of these issues, but at a high price.
