Ten times the speed of light.  :cool:

Warp Drive May Be More Feasible Than Thought, Scientists Say

HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once 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.

"There is hope," Harold "Sonny" White of NASA's Johnson Space Center said here Friday (Sept. 14) at the 100 Year Starship Symposium, a meeting to discuss the challenges of interstellar spaceflight.

Warping space-time

An Alcubierre warp drive would involve a football-shape spacecraft attached to a large ring encircling it. This ring, potentially made of exotic matter, would cause space-time to warp around the starship, creating a region of contracted space in front of it and expanded space behind.

Meanwhile, the starship itself would stay inside a bubble of flat space-time that wasn't being warped at all.

"Everything within space is restricted by the speed of light," explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. "But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."

With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.

The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.

But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.

Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.

"The findings I presented today change it from impractical to plausible and worth further investigation," White told SPACE.com. "The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab."

Laboratory tests

White and his colleagues have begun experimenting with a mini version of the warp drive in their laboratory.

They set up what they call the White-Juday Warp Field Interferometer at the Johnson Space Center, essentially creating a laser interferometer that instigates micro versions of space-time warps.

"We're trying to see if we can generate a very tiny instance of this in a tabletop experiment, to try to perturb space-time by one part in 10 million," White said.

He called the project a "humble experiment" compared to what would be needed for a real warp drive, but said it represents a promising first step.

And other scientists stressed that even outlandish-sounding ideas, such as the warp drive, need to be considered if humanity is serious about traveling to other stars.

"If we're ever going to become a true spacefaring civilization, we're going to have to think outside the box a little bit, we're going to have to be a little bit audacious," Obousy said.

I never take seriously any article in popular science that uses the phrase "scientists say"  in a sentence.

A terrorist which starts a slaughter quoting Locke, Burke and Mill has completely missed the point.

Didn't the Planet Express Ship in Futurama work the same way? I remember a statement by the Professor that the "engines operate at 200% efficiency and move the entire Universe around the ship." (This was how he refuted an argument from his clone that FTL was impossible.) In another episode I believe it was stated that the speed of light was changed at some point prior to the series and the ship can travel at 97% of the new light speed  :lol:.

These are probably the same scientists JJ Abrams pays consulting fees to.

Let us know how this works out for you.

The scientists.

I mean it's great they have this theory, but given that they've got no evidence this will work I don't see any reason for the hype the story's getting. It's on every geek site, facebook, etc.

The internet can cause minor news to bubble to prominence pretty quickly. This actually isn't really a big deal, scientists have been speculating about this since at least the early 90s.

Oh, so we just need a big ring of 'exotic matter'.  Well, that's alright then.

Because we're not investing billions in some fantasy contraption?

Well, they are apparently going to do some experiments, so it's not like they just wrote a paper and are going to leave it at that.

The money our governments have sunk into space exploration, as well as the huge number of books & movies on the subject suggests mankind is interested. It's just not something we're willing to sacrifice for.
