There was a great show on the History channel tonight called "Alien Engineering." It basically backed up everything I said about interstellar travel in that other thread about aliens where I got flamed to death, I hope this one doesn't turn out that way. Though the alien spacecraft that was recovered and hacked into was fictional, the physics of the show are real. They talk about everything from anti-gravity propulsion to Einstein Rosen bridges (a.k.a worm holes). If there is any chance of humans traveling to other star systems, or a chance of other species traveling here, this is how it will happen. I not gonna go into great detail about what was on the show, you'd have to watch it for yourself, but basically they theorized about a way to travel to distant star systems quicker than the speed of light without the relativistic effects of light speed travel, since you would not be traveling at the speed of light when going through a worm hole. They go over how anti gravity works, and how it would enable a craft to perform all of the difficult maneuvers that people have reported to see UFO's perform, like coming to a dead stop and making a 90 degree turn. Now, Im not suggesting that this is proof that extraterrestrials have visited out planet, but now that we know that it is possible to obtain the technology to travel these great distances, doesn't it make it much more likely that extraterrestrials could travel here?
Just FYI since most of you called me many different names for thinking it was possible to perform interstellar travel. Keep your eyes open to see if it's on again sometime this week, part two is on next monday night, it should be really good.
My intentions with this thread is just to provide you with an interesting piece of information and hopefully not turn out like the other thread. This is more about interstellar travel than about aliens, so please don't flame the hell out of me.
