Steve Paikin from TVO The Agenda interviews Dr. Michio Kaku.
A fascinating talk covering topics from Dr. Michio Kaku's book "Physics of the Impossible".
Subjects discussed range from psychokinesis and telepathy to teleportation and time travel. Impossibilities are split into classes
Class I. Impossibilities Includes force fields, telepathy and antiuniverses. These don't violate the current known laws of science & could be become reality within the next 100 years or so.
Class II. Impossibilities Includes faster than the speed of light travel and parallel universes.
Class III Impossibilities Includes perpetual motion machines and precognition.
In the distant future the need for tons of advanced technology to land payloads on distant planets could be a thing of the past. What will be evidently needed is the ability to harness a power source that is beyond comprehension. The only thing I can say to that is "Beam me up Scotty".
