Mike
Carruthers:
Some of what was once considered science fiction years ago has become reality;
things like space travel and computers. But what about some of the other things
like invisibility?
Michio
Kaku:
We're closing in very rapidly on invisibility. Under red
laser light, we can already bend red laser light in a way consistent with invisibility.
So I think maybe in ten years if we were to shine red light on an object, it would
be invisible. Physicist
Michio Kaku, author of the book Physics
of the Impossible… Later
we'll get the three primary colors - red, green and blue and after that we may
be able to make an object totally disappear into visible frequencies. In
science fiction stories you sometimes see these advanced creatures who can move
objects with their mind. We're
very close to that now, in the sense that if I have a stroke victim (someone who's
paralyzed), we can now put a chip on top of this paralyzed person's brain, hook
it up to a laptop so he can move the cursor on the screen. And now these people
can play video games, they can write email, answer email and surf the web and
this is done strictly by thinking about it. And
what about time travel? Time
travel is further down the line, not decades but centuries down the line when
we have enough energy to manipulate black hole-like objects. Then it may be possible
to bend time into a pretzel. Tomorrow,
what about the possibility of perpetual motion? I'm Mike Carruthers and that's
