NASA Actually Working on Faster-than-Light Warp Drive

Article: http://techland.time.com/2012/09/19/nas ... arp-drive/

Videos on the subject discussed: https://www.youtube.com/results?search_query=Alcubierre

Late last year, it emerged that a small team of NASA researchers were working on warp drive technology in the lab. Led by Harold “Sonny” White, the team devised a variation of the Alcubierre warp drive that could almost be feasibly produced — if we can work out how to produce and store antimatter. Now, White is ready to discuss some other facets of his warp drive, such as the energy requirements, what a spacecraft with a warp drive would look like, and what it would be like to travel at warp speed.

When it comes to interstellar travel, due to the massive distances involved, the only feasible solution for reaching other planets and stars is a method of transport that travels at close to or faster than the speed of light. The nearest star system, Alpha Centauri, is just over four light years away — at a speed of 62,136 kmh (the speed at which Voyager-1 is flying through space), it would take roughly 67,000 years for a spacecraft to reach it. There are a variety of proposed propulsion systems, such as ion drives, but none of them really get close to the speeds necessary to enable the exploration of other planets in under a few thousand years. Warp drives, while years away from even small-scale testing — if they’re even possible at all — are one of the few exceptions that would allow same-lifetime space travel.

As the name suggests, a warp drive enables faster-than-light travel by warping space-time around it. In essence, Miguel Alcubierre proposed a device that causes the space in front of the spacecraft to contract, while the space behind it expands. This creates a warp bubble that carries the spacecraft through space-time at 10 times the speed of light. We know from our observations of the universe that such deformation of space-time is probably possible, but in this case there’s a huge step between theoretical and experimental possibility. There are numerous problems with an Alcubierre drive — such as whether you’d be able to survive inside the bubble, or my personal favorite: annihilating the entire star system when you arrive at your destination — but the sheer amount of energy required to reach the speed of light, let alone surpass it, is probably the main drawback.

Last year, Sonny White revealed a new design (pictured top) for the Alcubierre drive that reduces the energy requirement from the total mass-energy of a planet the size of Jupiter, down to the mass-energy of Voyager-1 (700 kilograms). We say “mass-energy,” because no one quite knows how to fuel an Alcubierre drive, with some research suggesting that it might require more energy than the mass of the observable universe, or possibly negative amounts of energy. Basically, though, according to NASA’s preliminary research, the energy requirements appear to be somewhat feasible if the drive is donut shaped rather than a flat disc.

Harold White, with a small warp driveSpeaking to New Scientist, Sonny White has filled in a few of the questions posed by his team’s original 2012 study. He begins with a warp bubble analogy, to help explain how superluminal (faster-than-light) travel is even possible in the first place: “You are walking along at 3 miles an hour, and then you step onto [a moving airport walkway]. You are still walking at 3 miles an hour, but you are covering the distance much more quickly relative to somebody who isn’t on the belt.” Speaking about what it would actually feel like to travel at warp speed, White says “you would have an initial velocity as you set off… It would be like watching a film in fast forward.”

What would a warp drive-equipped spacecraft look like? “Imagine an American football, for simplicity, that has a toroidal ring around it attached with pylons. The football is where the crew and robotic systems would be, while the ring would contain exotic matter.” Here the “exotic matter” is an energy source that we don’t know a whole lot about (thus why we use phrases such as “the mass-energy of Jupiter.”)

Finally, White warns us that the first real-world warp drives are a long way away. The NASA research team have some “very specific and controlled steps to take to create a proof of concept,” to see if the physics of the Alcubierre warp drive actually play out in practice, but we’re talking about a microscopic warp bubble that will have very little relation to a real-world prototype. We are probably looking at a decade or more before we can create a car-sized warp drive — and even then, that’s only if we can find some of that elusive “exotic matter,” which we probably won’t.

Hypothetically speaking - if we are indeed being visited by Extraterrestrials from another start system, it would be a fair guess that they have gotten around the problem of traversing such unimaginable distances.

I personally think it would take and lot of money and huge scientific effort, to pull something like that off. That said, maybe someone else - some other more clandestine organisation with "unlimited funding", is secretly working on such ideas?

This is an interesting Theory all though faster than the speed of light to me is possible but does not really apply here. Despite the fact that the models shown are of a "wave" of space and do not show 3d modeling which even I a 3rd grade educated person [as some have said.] have prbs with imagining the 3d ...football so to say on this 2d wave. It is not a wave! Must be 3d+ in space. Where is the rest and the relation of?

That said the Theory being brought forth is more of a bending of time or "fabric" of space. Like a "jump" so to say. Not actually exceeding the speed of light but a warp in this 2d fabric of space ..so to say. I feel that 2 theories are being applied to make this happen. May be possible but the hodge podg science makes me a bit skeptical.

Do not get me wrong. It is feasible but I have a peeve with those that present 2d fabric of space theories/modeling that are not the true perspective of space and other things/object/s and their effects that may bring question to such theories.



Nice post to get some neurons firing but flaws are evident. :cheers:

I read a paper somewhere that said this idea is fundamentally flawed because, even if space-time (ST) is contracted, the trip isn't any shorter and the speed isn't increased. Why? Because once the effect is turned off, ST snaps back and the trip is reestablished at the original distance.

So why not travel through the contracted ST and make the effect permanent? Because the craft too would contract (since it exists in the same ST) and the perceived distance would still be the same. There's no shortcut unless ST is ripped into a wormhole.

Other parts of this universe or other "dimensions." There certainly is something to the systems being used in this type of travel compared to anything we are currently knowledgeable of in the main stream science/media filed.

You know it!


I have to thank you for giving me the tip to check out the news on this subject however. It was new to me.

I thought that too. A bit like when you expand an elastic band: once you let it go, it will snap back to the point of expansion.

Alcubierre does make a vague reference to what you mention; but he states that essentially, the craft would "surf" the vacuum. The craft, once emergence took place, would in theory emerge from "meta" space into normal space in a different location.

It is all theoretical at the end of the day; and for me personally, fun to get my head around. It has definitely helped with my sleeping problem.

It's done for years...

Check out a planet of the apes fan site... called faster than light there's theory and illustrations of a space bending system

It's difficult for me tocopy links from my phone... I've been in space once... Earth to jupiterin three minutes dock to dock...

Edit: There's a new rock band called... thirty second to mars... LOL
:cheers:

Good evening ,
I think that is a bad analogy, cause you are holding in one hand a elastic band, and the other hand starts streatching thr band, the first hand releases the band and the band will return to its original size and at the other side of the hand, and not in the original location.

For what I understood the warp engine would compress the space ahead of the space craft, the spacecraft would then fall into that compressed space, or surf, but would never reach that space cause the compressed space would then be ahead again, as the spacecraft moved away, the compressed space would return to its original "size" and this too would push the ship forward.

If I am not mistaken the study that claims the destruction wave would destroy everything in its path or at the arrival place has been challenged with sucess.
