Michio Kaku: 5 fascinating moments from this 1991 interview

From talking about Schrödinger's cat to nuking the South Pole, this decades-old interview shows why Kaku was born to be a science educator.

Harold Channer
  • Michio Kaku is a theoretical physicist and renowned science communicator.
  • In 1991, he sat down for an hour-long interview in which he discussed climate change, nuclear weapons, human evolution, and more.
  • Kaku is a regular contributor to Big Think.

Is panpsychism accurate? Modern physics delivers a reality check.

If philosophers don't try to mesh their long-held views with new scientific insights, then we have a problem.

  • According to panpsychists, all of reality is infused with experience. In other words, the fundamental ingredient of reality, they believe, has the felt quality of experience in it.
  • In this view, the reason that we humans are conscious is that we're configured based on these fundamental experiential ingredients.
  • If philosophers don't try to mesh their long-held views with what we're discovering from good science, then we have a problem. For instance, panpsychism may be due for an update: panprotopsychism, a view that says as these fundamental ingredients combine, they give rise to conscious experience and that those fundamental ingredients are "quasimental."

  • Science fiction has long speculated about parallel universes and what they may be like.
  • Researchers have devised new experiments to look for how a mirror universe may be influencing our own.
  • If such evidence is found, it could bring to light many of the universe's mysteries, such as the nature of dark matter.

Physicists puzzled by strange numbers that could explain reality

Eight-dimensional octonions may hold the clues to solve fundamental mysteries.

  • Physicists discover complex numbers called octonions that work in 8 dimensions.
  • The numbers have been found linked to fundamental forces of reality.
  • Understanding octonions can lead to a new model of physics.
