“Routine travel among the stars is impossible without new discoveries regarding the fabric of space and time, or capability to manipulate it for our needs,” says Neil deGrasse Tyson, the "Cosmos famous" astrophysicist at the American Museum of Natural History, said “By my read, the idea of a functioning warp drive remains far-fetched, but the real take-away is that people are thinking about it — reminding us all that the urge to explore continues to run deep in our species."

There have been hints in recent news that NASA may be on the path to discovering warp bubbles that could make the local universe accessible for human exploration. NASA scientists may be close announcing they may have broken the speed of light. According to state-of-the art theory, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months.

The catalyst for the trending warp-drive excitement is the Electromagnetic Drive or EM Drive, a thruster that was engineered to steer rockets which eliminates the use of a propellant originally intended for moon missions, Mars missions and low-Earth orbit (LEO) operations.

The experiment that led to the possibility of faster than light interstellar travel took place in the vacuum of space. According to posts on NASASpaceFlight.com, a website devoted to the engineering side of space news, when lasers were fired through the EmDrive’s resonance chamber, some of the beams appeared to travel faster than the speed of light. If that’s true, it would mean that the EmDrive is producing a warp field or bubble. 

But "How?" If the laser beams are moving faster than the speed of light, then it would indicate that they are creating some sort of warp field, or bubble in the space-time foam, which in turn produces the thrust that could, in theory, power a spaceship bound for the center of the Milky Way or one of its dwarf galaxy satellites.

The bubble would contract space-time in front of the ship, flow over the ship, then expand back to normality behind it. It’s inaccurate to describe the spaceship as moving faster than the speed of light, but rather space-time is moving around the ship faster than the speed of light.

Harold G. White, a physicist and advanced propulsion engineer at NASA and other NASA engineers are trying to determine whether faster-than-light travel — warp drive — might someday be possible. The team has attempting to slightly warp the trajectory of a photon, changing the distance it travels in a certain area, and then observing the change with a device called an interferometer.

“Space has been expanding since the Big Bang 13.7 billion years ago,” said Dr. White, 43, who runs the research project told the New York Times. “And we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve went receding away from each other at very rapid speeds. Nature can do it,” he added. “So the question is, can we do it?”

In 1994, a Mexican physicist, Miguel Alcubierre, theorized that faster-than-light speeds were possible in a way that did not contradict Einstein by harnessing the expansion and contraction of space itself. Under Dr. Alcubierre’s hypothesis, a ship still couldn’t exceed light speed in a local region of space. But a theoretical propulsion system he sketched out manipulated space-time by generating a so-called “warp bubble” that would expand space on one side of a spacecraft and contract it on another.

An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light/"

Alcubierre-warp-drive-manifold“In this way, the spaceship will be pushed away from the Earth and pulled towards a distant star by space-time itself,” Dr. Alcubierre wrote. Dr. White, the NYT reports, has likened it to stepping onto a moving walkway at an airport.

Alcubierre’s theory, however, depended on large amounts of a little understood or observed type of “exotic matter” that violates typical physical laws.

In general relativity, one often first specifies a plausible distribution of matter and energy, and then finds the geometry of the spacetime associated with it; but it is also possible to run the Einstein field equations in the other direction, first specifying a metric and then finding the energy-momentum tensor associated with it, and this is what Alcubierre did in building his metric. This practice means that the solution can violate various energy conditions and require exotic matter. The need for exotic matter leads to questions about whether it is actually possible to find a way to distribute the matter in an initial spacetime which lacks a "warp bubble" in such a way that the bubble will be created at a later time.

Yet another problem according to Serguei Krasnikov is that it would be impossible to generate the bubble without being able to force the exotic matter to move at locally FTL speeds, which would require the existence of tachyons. Some methods have been suggested which would avoid the problem of tachyonic motion, but would probably generate a naked singularity at the front of the bubble.

Dr. White believes that advances he and others have made render warp speed less implausible. Among other things, he has redesigned the theoretical warp-traveling spacecraft — and in particular a ring around it that is key to its propulsion system — in a way that he believes will greatly reduce the energy requirements. But ”We’re not bolting this to a spacecraft,” he said of the technology.

Richard Obousy, a physicist who is president of Icarus Interstellar, a nonprofit group composed of volunteers collaborating on starship design, said “it is not airy-fairy, pie in the sky. We tend to overestimate what we can do on short time scales, but I think we massively underestimate what we can do on longer time scales.”

Dr. White likened his experiments to the early stages of the WW 11 Manhattan Project, which were aimed at creating a very small nuclear reaction merely as proof that it could be done.

Still, one of the most dubious is Dr. Alcubierre himself. He listed a number of concerns, starting with the vast amounts of exotic matter that would be needed. “The warp drive on this ground alone is impossible,” he said. “At speeds larger than the speed of light, the front of the warp bubble cannot be reached by any signal from within the ship,” he said. “This does not just mean we can’t turn it off; it is much worse. It means we can’t even turn it on in the first place.”

The very idea of intersteller travel is never the less provoking research. It is my guess that most of the UFO sightings are our own craft. You can postulate reverse engineering from downed craft, you can postulate that U.S. Government research has indeed invented a non fueled drive (well, fueled by a non combustible non chemical resource of energy). UFOs are seen commonly and all a UFO is, is a supposed unidentified object..unidentified by the viewer and unidentified by authorites. To identify an object one must know that there is a category for it...if there is no category, hence unidentification or UFO. "Flying" itself may lead to erroneous concepts... they are not flying at all..to fly an object must rely on aeordynanics which UFOs apparently don't. I prefer to call them simply UOs, unidentified objects.

Obviously to me anyway, they exist or thousands of folks each few months would not see and photograph/video them. Yes there are lots of hoaxey videos on youtube, that's unfortunate, but there are some legitimate ones...videos of things which are not explained by governments. Would the first atomic test's light in the night sky be immediately explained by the government to viewers of such? "Look Martha, that light coming from over the horizon!" You can bet that the government wanted to keep this secret for as long as possible as to the source...to surprise the Japanese. Then the 2nd test... then Japan. Likewise UFOs are not going to be let out of the bag just yet...leastwise OUR UFOs...or craft that have the luxury of drives which permit them to go exceedingly fast and seemingly defy momentum. I don't think they defy momentum, I think that a bubble or "condition" is arranged so that they seem to defy momentum.

I don't think any physics rules are violated at all, anywhere, I do think mankind doesn't understand all the rules.

As time goes on we will discover that its actually possible to travel much faster than light. Space or dark energy has no limit on the speed of its expansion. It is nearly infinitely "flexible." The only limit is the local energy provided. Space can expand billions of times faster than light. It has done so before, at the Big Bang. Thats why radiation from the big bag only reach us now, as we have moved WITH space billions of times faster than light could travel (1C) in that space. Imagine shouting in a field, then running so fast, so far then stopping. You would have to wait for your own voice to reach you and it will in time. "Distance" as we know it, is a valid parameter only "within space-time". Once space can be compressed or stretched, distance has a lot less meaning, since it can be reduced to zero and traversed in zero time. The theory behind the warp drive is sound, some difficulties in directional mechanics have to be overcome, especially in the presence of large gravity fields. With a warp ship, local space distortion would interfere with navigation but it can be compensated for. Given enough funds and manpower, a warp ship would be possible within the next 30 years. Once that is possible, there will be mining / space manufacturing corporations that will make Apple look like a local diner.

Baby Steps, Children- Baby Steps.How do you talk-etc. inside/ outside your little gravity bubble around your own planet?

I have much to say on this topic little of which would be taken seriously, but I'm pretty excited for the thought of testing something that averages 5c (important) and that as I understand is orders of magnitude faster when you have a real look. It;s an important step for humanity. It has to be really digested that the theoretical and even engineering people that designed and built this (soon to be tested as I understand) technology are quite public in their disclosure that it's really a mystery to them. I commend them for stepping forward with honesty rather than making something plausible but untrue to hide their ignorance. It is very brave. My opinion shouldn't be taken to gravely and is likely easily misunderstood. You are not going to be very happy with what you find waiting for you as we walk through this doorway. It is not what you expect, and it will be difficult. I highly recommend we go about it with very clear intentions that our civilization is crossing a threshold. The hardest part will be looking back home and finally knowing what we have done. Congratulations everybody, and though I suspect there is less ignorance than feigned, if you are seriously jammed up there are lots of people who know these technologies very well all around you. Like it or not. Aliens didn't drop us a bone or crash and we took this to reverse engineer. Not this time. This is our own technology and that is a very big deal. Get a Welcome matt, you've needed one for a very long time. and it's about to get plenty of use. Also, Micayo what you are talking about is not a spaceship, from what I understand. It's your body.

Charley I hate to disappoint you but the universe does not work the way we have been taught and it is a functioning prototype, it is FTL, and the inventor is (in this idiot's opinion) the only person who has a grasp I do not mean to belittle the foam discussion is right on the money as well.

Also you will not be chasing down ETs in a jalopy like this (no offense) so don't get too worked up.
We aren't going anywhere yet and, I, personally and particularly and publicly assure you.
We are not allowed in space until we grow up. Sorry Terror Planet, you are to sick to leave bed so please just get better soon.

A Friend who is well traveled enough to know

When the functioning mechanism is understood in proper context (again, i remind you i'm an idiot) much becomes clear. 100 years is long enough worrying about an imaginary cat and which afterlife or social event he may/may not be attending. I'm being sarcastic intentionally. If you try to pick it up and measure the forces in an attempt to resolve the apparent (<-- a word i am using like a knife) you are going to spin and derail and need to face that you are seeing the foundations of our sciences looking in a mirror to nowhere. It's a very serious problem.

Try this. The tech is real, so start making stuff. (<-- yeah, stuff) and it will come to you. These are new and unusual places. For those of you who don't build advanced interstellar spaceships, they have been around a long time, humans have but did not invent them. Until now, it's new, give it time, you'll adapt. If you think I'm nuts I will say thank you, I certainly hope so. Read the article again, the people who have successfully (it works, there is a part not in the engine, it's vestigial <-very very purposely used part and without it you won't find the answer. You don't have the tools yet (my friends do build advanced interstellar vehicles that are more like their dog than their car, so just get accustomed to things being far out. that is the most important lesson you will learn in free space (intention) when you are released from quarantine (for your and all benefit) and meet all the lovely and very far out things Literally Waiting For You it's not such a big deal. Not after what you will have just experienced anyway. If you just can't handle the fact that life is essentially everywhere that;s a shame, most things are friendly, as wise and magical as Gandalf, and genuinely excited to meet you. Also your show is a big hit. See you at the salad bar.
