Do YOU believe in space aliens?

Hmm, nifty as that may be, I don't see how it contradicts Einstein in the least. Einstein's theory maintains that the speed of light in a vacuum is constant. No one has evern argued that it reamins constant through all media, and as a matter of fact, it's easily proveable that it doesn't (have a prizm handy?). While it's incredibly impressive that they managed to create a medium through which light travels part way, then stops, it's not contrary to what we already know.

Contradicts? What you think I want to get hung? I said enhanced.

15 Years ago (ok, 20..) my physics prof's were quite SURE you would never be able to stop light. Slow it down in diffrent substances sure but stop? No way not possible. <-- Notes from actual conversation.

Oh and one bit of trivia, Einstein himself NEVER said FTL travel was impossible. That thought was added by others.

Moonliner - interesting info, but a couple of comments -

The stars that are 4 light years away, to my knowledge, have no evidence of planets orbiting them. We are currently finding many planets around stars much farther away. This is why I started at 10 light years away.

We do not defy gravity in flight. Instead, we apply physics of create lift (Bernoulli, if I am spelling his name correctly) and can generate enough thrust to overcome the gravity of earth. In terms of curving space enough to travel to other areas of the galaxy faster, we are talking about gravitational forces millions of times more powerful than our sun, and I do not believe we will ever harness that type of energy.

May I be allowed to quote my own earlier post?

So may I say we are agreed?


As for the planets, most (but not all) of the objects discovered to date are Jupiter or larger in size. I don't think it is as yet safe to rule out earth type planets around the closer stars.
