“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.”

What is exactly that "exotic matter" that is referred to several times?

David, I believe they are referring to either tachyons or antimatter.

The "Exotic Matter" they are speaking of is "Negative Energy" and/or "Negative Matter" as this is what most, if not all previous warp drive engine concepts used to actually warp spacetime.

This are extremely difficult forms of matter/energy to get, though not as hard to KEEP as antimatter, as they at least don't annihilate on contact with matter like antimatter...

In the new models you don't need exotic matter at all. The warp bubble is created with strong electromagnetic fields.

Not going to happen for many hundreds of years or longer. Besides, how are we going to maneuver this craft while traveling at the speed of light? Oh Sh!t Scotty there's a planet dead ahead, turn right!! LOL.

The important thing to remember is that the warp bubbles that are being investigated are variable in intensity/effect. If you have the energy you can stretch space at up to 10x the SoL. But, for those of us on more modest energy budgets, you could dial up 0.1x the SoL for a trip to the Kiper Belt, .001x for that hour long jaunt to the moon, of maybe .00001x to move an ocean liner across the Pacific. It would be a game changer.

Anyone know if the author is suggesting the superluminal properties and effects taking place were'nt noticed until operated in a microgravity environment? As if the earths gravity disrupts the phenomena? A warp drive that fails in the presence of a massive object in space may not be a reliable means of travel in space.

It's faster than light travel.

Silly humans ....., since Zefram Cochrane (The inventor of the warp drive) is currently only two years old we will have to wait until 2063 for these questions about the Alcubierre Warp Drive to be answered!

Interesting article... needs proofreading though

Forget these warp bubbles,this is a joke right !!!.the only way to travel from point to point in our universe would be by hopping on a electromagnetic filament stream.you could then surf the universe at will.it would only be necessary to attach your craft with a positively charged magnetic field which would be easily controlled for speed and decelerations.so what we should be concentrating on is how we can find a way to make this connection.

"lasers were fired through the EmDrive’s resonance chamber, some of the beams appeared to travel faster than the speed of light." ok.what wos the power of thise lasers? let´s try changing the input a bit.. how about these http://www.gizmag.com/berkely-world-record-compact-particle-accelerator/35118/

Back to reality folks!! There is absolutely ZERO purpose to travel at the speed of light, to anywhere, for many many reasons. We haven't been back to the moon in 40+ years and we are talking about warp drives, to travel the galaxy.........humans can't survive without gravity, at least not for the length of time it would take to travel to a distant star, period.

Interesting concepts.

We'll have commercial application of warp drives in 25-40 years (that's the way human culture rolls these days). Interstellar travel. Meeting our neighbors. Wars to satisfy our most primal instincts. Wonderful future...but how to keep control over those vast new territories? That's the real question. The future reads like a 'C' grade sci-fi movie, all minor actors and chaotic.

if that thing is a warp bubble that it might be considered like an active agent of surface for which you have a liquid or a another, media than what is might be the dark matter or the ether or the cold from the moment that the galaxies are already floating?

First of all the space ship's bubble or bow wave compression of space/time as I prefer to call it, and stern wave of decompression of space/time would require the use of an incredible amount of energy impossible to store on a space craft...it would have to use energy from the interstellar medium itself...and that is not impossible. But first we'd have to discover what the energy is, some call it dark energy for they have no idea what it is, but it exists...we just can't identify it yet.

Second, we don't understand what space/time is in the first place. It's like trying to invent a car and we have not the slightest inkling of the energy we'd use to run it...gasoline or electricity, hence cars were not invented before the discovery of these two energy sources.

I don't like the analogy of compression of space/time and the decompression of it. Rather I like the concept of a universe consisting of a grid made up of space bits and time bits. For every space bit there is a time bit....in a 3D grid work like a checker board of black and red squares. To go from point A to point B you need to pass by less time bits than space bits, even if traveling at 1 kilometer per hour.

I don't like the abbreviation of faster than light as FTL, why not just use "+C", for "C" represents the speed of light in Einstein's formula?

Let's suppose humankind does develop a way to go from point A to point B in +C. Mankind's psyche is so seriously flawed with greed, aggression and corruption, that do you really think the interstellar community would even let man= kind out of the Oort cloud into interstellar space in the first place? Heck no, or would at most escort us out and back in again as if on parole.

Not only that but figure on the collision damage of a space craft just hitting a dust particle at C+ let alone a larger chunk of matter. Talk about a hypervelocity projectile frpm Hades...that would be your spaceship colliding with something as small as a grain of pollen. You simply can't just go through matter unscathed because you are matter yourself.

I do believe it is very highly probable that alien civilizations are visiting us at faster than light speeds, it's a question of how the heck the do it and can a human being sustain the trip physically?

They've got a very long way to go in all cases before interstellar travel can be done, albeit change the entire psyche of humankind first and foremost THEN figure out how to tap into the universe's "medium" of energy shall we call it, then develop the "drive" so to speak to use more space bits than time bits and so on. It's going to take a while if ever, given we are even allowed to leave the Oort cloud.

Sometimes I wonder if NASA ESA or any other Institute involved in this research are giving massive budget more than military budget, is there a possibility for faster than light travel? I don't think money would do it, time might be required. Maybe it's impossible

Long headline /question - very short answer: NO!

Lost me at "time travel"

Time is a basic measurement, not something that can be altered or manipulated in any way. Same shit different viewpoint.
Lets stick to space travel.

Lets quit all this negative jargon. first of all fifty years ago the idea of this stuff was impossible in every way shape and form. Now our understanding of stuff is coming to the point where it might be possible. Which is absolutely great.

We have the em drive( propulsion with no propellant) and a possible warp drive. Maybe these are the technologies that needed to be invented.

Also time is relative. It isn't a set constant and they have proof of this in the satellites that orbit our planet. They are moving so fast that they're on board clocks move at a slower rate granted it is like 10 micro seconds an hour.

Just the fact we are talking about the actual possibility of this stuff coming to fruition was impossible 50 years ago.

Aren´t we forgetting some important bits here? Almost everything proposed here is a theory. No one started building stuff, or is planning to. It´s just a theory. It´s unknown how to get the energy, how to deal with the radiation and several other problems more.It might need ten years, a hundred years or in fact much longer to create a working, stable drive, but we have a theory nevertheless.

The combustion engine wasn´t build in three days either; it took many years to develop it, and several years more until it was efficient at all. And here, we are talking about traveling distances which are not imaginable for quite a lot of people.

I don´t see myself OR my grandchildren go beyond the solar system, yet. But this shouldn´t stop us as humanity to try anyway. After all, just as a combustion engine and aerial flight, everything has to start with a theory.


Time warp bubbles are the way to time travel and travel many light years in days and weeks NOT months. Also try installing gravity amplifiers in your space truck, this technology will get you to the stars quickly as well.

Actually NOTHING proposed here is theory. Theory requires proof to define it as theory. I see lots of ideas...mine included. I never said what I posted above was a theory and to make this specific, what I said about space "bits" and time "bits" is my IDEA for I have no proof.

But.

One poster of some was correct, there is no way that enough energy can be stored on a space craft to furnish interstellar travel, and yes, that energy must be derived from the universe's "reservoirs" of energy as the mission proceeds, not filled into an energy tank on Earth to ignite and blast a ship out at warp 4.
