Michio Kaku: Why We Can't "Fire the Photon Torpedoes"
Propelling a spaceship with photons would be like trying to energize a spaceship with a flashlight. Today, Dr. Kaku addresses a question posed by Serge ...
========== Serge, some people have dreamed about photon
power it sounds like a great concept right it's a great word but then you have to realize
the practical problems on Star Trek they say fire the photon torpedoes well what is a photon
torpedo a photon torpedo is a flashlight because what is the photon a photon is a particle
of light that's all it is so you're basically trying to energize a spaceship with a flashlight
so now you begin to realize the problem it sounds really neat it sounds science-fiction
but the reality is the practical engineering is very difficult yes flashlights have an
impulse if you turn on a flashlight you can actually measure the fact that the flashlight
is moving slightly because of the impulse created by shooting our photons but it's very
small and that's th...
