Toloran writes "Although a staple of Sci-Fi space travel, it is often deemed to be just that: Fiction. However, it seems that one is currently in development. "The theoretical engine works by creating an intense magnetic field that, according to ideas first developed by the late scientist Burkhard Heim in the 1950s, would produce a gravitational field and result in thrust for a spacecraft. Also, if a large enough magnetic field was created, the craft would slip into a different dimension, where the speed of light is faster, allowing incredible speeds to be reached. Switching off the magnetic field would result in the engine reappearing in our current dimension.""

Anyway, its the press.
The drive is no warp drive. And the idea is NOT to slip it into a different dimension, at least not as far as I understood the stuff about Heim I read so far.
Heim has a somewhat unified theory about forces. Like Lorenz force, that is a force affecting charged particles, the Heim-Lorenz force affects any particle that has mass. (But the force still needs to be shown to exist in experiments)
According to that unified theory you only need compareable weak magnetic fields (compareable like on the surface of our sun, don't remember the exact numbers, but I googled once for references and I think I remember the strength of the field was a bit below the magnetic field of the sun) I think the field needs to be somewhat in the order of 10 times as strong as in the current fusion experiiments.
Such a field would basically work like an "anti grav" drive, not like a warp dirve, and no, you would not be faster than light, you only could speed up pretty easy. In fact I have no clue how you just would use a field as drive anyway

Depends on the physics. There was a bomber designed back in WWII that looked a lot like the B-2. However, it was very hard to control due to no vertical stabilizers. 50 years later and computer controls, we have one of the most impressive bombers ever built. The SCRAM Jet was SciFi until we got new materials, so were forward swept wings on a super sonic jet. Sometimes it's just a matter of letting practical science catch up with the theory. After all, if all it takes is more power, wait until you have a denser working power plant.

There's no evidence. There's no theory. It's just something somebody made up.
Einstein thought that they did. The ultimate goal of general relativity for Einstein was a Grand Unified Theory of Everything. In Einstein's conception, all forces (not just gravity) were the effect of curvatures in space-time. Since all energy was curvatures of space-time, so was all matter. Heim just expounded on Einstein's theories and he did so in a way that actually predicts the masses of fundamental particles. Thinking hard on relativity was what he did to distract himself from the pain of from where his hands used to be after they were blown off in an explosives lab accident. The same incident made him deaf-blind, so he preferred isolation rather than colaboration and pretty much spent all his time on the subject. This same isolation made his theories relatively unknown for a very long time.
The editorial blurb is hideously sensational, though. Even if we do prove that EM fields can alter space and produce gravitational effects, you're a long way from creating a practical form of propulsion. On the other hand, we'd at least have hope of a reactionless drive.

A method to cheaply and easily turn any given substance into gold has long been the goal of alchemy, and widely regarded as fantasy. However, it seems that one is currently in development. According to slashdot user Control Group: "the theoretical process works by imbuing heavy metals - such as lead - with the essence of the sun's emanatory spirit, resulting in the lead taking on a yellowish hue. Also, if enough essence is crammed into any given substance, the very nature of it is changed, allowing incredible transformations to be performed.

Someone comes up with a theory that may permit FTL space travel. There isn't any known way to test the theory with the current techniques.
Sometime later someone comes up with a way to test the theory to see if it works or not (we are here).
If the theory works, the nature of human society changes forever as we become a true spacefaring race.
If the theory fails to hold up then we've disproven it and learned something new about the nature of the universe in the process (or possibly just confirmed a different conflicting theory).

Antimatter may be the ultimate in energy density, but it is not the ultimate in energy storage. It takes a tremendous amount of energy to create that antimatter, much more than you will get from its annihilation with matter.
On to the "trivial" rockets, you may be able to produce lots of thrust with a matter/antimatter engine, but you also produce enormous amounts of radiation. How will you shield the crew compartment, or even the electronics? Lots of heavy metals? More mass = less acceleration.
Finally, the net world production of antimatter is what, femtograms per year? We're nowhere near ready to fuel even one bottle rocket, let alone a spaceship.

This is mostly a myth. Virtually every physicist associated with the Manhattan Project came independently to the conclusion that a nuclear bomb would not ignite the atmosphere, based on what was known about the nuclear cross-sections of atmospheric atoms (which was a lot).
I guess it's possible that some unknown physics could have resulted in ignition of the atmosphere anyway, but we are always at risk from that, so it's somewhat silly to worry about it. For instance, if current physics is wrong, a passing strangelet [wisegeek.com] could destroy the Earth at any moment.

Edward Teller also raised the speculative possibility that an atomic bomb might "ignite" the atmosphere, due to a hypothetical fusion reaction of nitrogen nuclei. Hans Bethe calculated, according to Robert Serber, that it could not happen. In his book The Road from Los Alamos, Bethe says a refutation was written by Konopinski, C. Marvin, and Teller as report LA-602 (declassified Feb. 1973, PDF), showing that ignition of the atmosphere was impossible, not just unlikely.

Admittedly Heim's work is not proven, but so far it's not disproven either. That's an important point. Heim (who was blind, mostly deaf, and was born without hands) has advanced a sort of Grand Unification Theory. It covers all the particles we know about, predicts the masses of those particles plus a few more that we haven't *proven* to exist yet, and doesn't suffer from the necessity of the Higgs Boson, which QM and ST predict, but which has yet to be seen (even though we really should have by now.)
It includes predictions of source of Dark Energy ("quintessence particles") and Dark Matter.
In all these respects, it is similar to any number of current Unification Theories. However, it has one set of properties that predict it should be possible to cause a gradient to form in the fabric of space-time, namely that by passing a set of particles through a massive magnetic field in a rotating torus, that it should be possible to cause the creation of a virtual particle pair known as the "gravitophoton" to form. This particle would then cause a compression of space time to form, giving a bias to space so that the generator would be moved in a particular direction.
The theory goes on to predict that if enough of a gradient was formed, then c' > c within the gradient (along with a bunch of other effects) that can't happen in real space. The only option that preserves GR is that the object must move out of "real" space into a parallel dimension/alternate reality where c'>c is allowed. Thus, faster than light travel.
The whole article is about the U.S. being interested in *testing* the theory. To do this, you build a big-ass torroid (6M) and get it spinning fast (> 700m/s) and then energize a big-ass magnetic field (>37 T) and measure to see if the effect occurs. The effect in this case measuring something like 3 newtons.
If it's there, then HURRAY AND HUZZAH, Heim was a genius who goes down in the history books with Einstein and we have warp drive within 100 years.
If it doesn't work, then the theory is proven wrong, and Heim wasted 19 years of his life doing some really obnoxiously hard math.
The thing is, this is just a physics experiment, no different than when Michelson and Morley set up their twin mirror experiment. And although it's a deceptively simple experiment, it could have just as big of repercussions as M&M's.
Calling it warp drive is premature. Saying it could have massive repercussions if sucessful is a huge understatement.

yes, Heim worked as you describe and his theroy is neither proven nor disproven, how ever its funny how "myths" starts to grow:
That's an important point. Heim (who was blind, mostly deaf, and was born without hands)
No, he was an ordinary physician. With hands, ears and eyes. But he played to much with explosives in his lab and was crippled in an accident, whre he lost his hands, and most of his sight and lots of his hearing.
Most of his theories he worked out AFTER that accident. His wife was writing it down for him and reading him older paragraphs. So most of his therory he made up in his mind and he enver could see the formulars his wife wrote for him on dictat.
Because he was such ill he did not want to travel, and he did not publish in that period. His late students revived his theories over the last 10 -20 years, and now as I mentioned in a diffeent post, they try to rewrite his theory and correct errors in his formulas and try to work out experiments to proof/disproof it.
Unfortunately most researchers find Heims idea contradicting to their picture of the world and reject it without even trying to udnerstand it. But well, its like with a difficult mathematical proof: the one who found the proof likely worked 5 or more years on that. If you like to understand his proof you have to spend at least one year in recalculations. In our time Heims theory is not popular and money to spend for experiements is going elsewhere.
However the basics of his theroy is pretty simple. And I assume its compareable easy to set up an exsperiemnt, or lets say: cheap. Far chaper than the fusion reactors we have built so far

-this proves nothing. you are still MOVING at 200mph in relation to the observer who is on the ground. and if you take 3 steps in a plane moving 200 mph, you've just traversed the same distance as the plane did...in 3 steps.
"Point B: The speed of light is NOT relative. It's always c. Always, always, always."
-nope. c = the speed of light in a vaccum. c can be much much slower when in a medium...such as water. scientists have recently been able to slow the speed of light down to walking speed.
The very word, RELATIVITY, indicates the complexity and the depth that must be considered when working with the laws of physics. The laws can change and DO change relative to where you are and how fast you are moving and any number of other factors.
