Warp Drive May Be More Feasible Than Thought, Scientists Say

A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre; however, subsequent calculations found that such a device would require prohibitive amounts of energy.

Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially bringing the idea back from the realm of science fiction into science.

I've always wondered - if you're in your car at night, traveling faster than the speed of light, and you turn your headlights on, what happens?

You can't go faster than the speed of light. As you approach the speed of light you and your car would essentially become a time machine. Time slows down as you reach the speed of light and if anyone could look inside of your car you would be moving in slow motion. So you could essentially bypass every season until we become a contentdor with out aging a bit.

Cool; I'd be up for checking out the 22d century.

Well, kind of. If the Bills could become relevent in the next 20 or even 200 years, it would be like a blip of time to the time traveller. If it takes another 2,000-20,000 years for Ralph to finally pass the reins, that time traveller will age as well. But we'll have the advantage of being dead by the time the Bills are finally relevant again. (And we won't have to suffer through the extra 180-19,980 years to get there.)

I've always heard that this last bit involving "time travel" w/o aging involved orbiting a black hole (at such an orbit/distance/speed so as to avoid getting sucked in) and then eventually leaving that orbit. The argument holds that the orbiter wouldn't have aged much, but hundreds/thousands of years would have gone by on Earth. It's not time travel as some think of it, but it does get the gist accomplished and while it'd bedamn difficult, will fail with disastrous effect if some little thing goes wrong and is probably a technological impossibility even trying to think. about what kind of technology is yet to come, it is theoretically possible, according to Hawking et al.

Same thing, actually. Those being the same thing (time dilation at speeds close to c/time dilation in a gravitational well) represent a fundamental concept of General Relativity.
