Warp Engines In Development?
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.""
What if my Apocalypse battleship slipped into a different dimension where the speed of light is slower, and it would take me another 200 years to move my finger to the 'OFF' switch 2cm away just to come back again.

This should be a fun post. At any rate, the interest of the Air Force does not provide any more credibility to this story. I've seen some *really* whacky ideas based on science fiction rather than science fact move through the DOD that says more to me about the state of science education in the US than anything else.

In another dimension, this would already be a dupe...
I think we can keep recursing like this until someone returns 1
It reminds me of the experiments with the first atomic bombs: they didn't know that the chain reaction wouldn't ignite the atmosphere.
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 could destroy the Earth at any moment.

Although a stable of Sci-Fi space travel
Staple. A *staple* of Sci-Fi space travel. A stable would be... well, I don't know what it would be, but it would be something else besides a staple.
People: spelling phonetically doesn't always work. This is getting "rediculous" [sic].
Libertarianism is rich wolves and poor sheep playing gambler's ruin for dinner.
All I want to know is why no one on Slashdot has pointed out yet that the link about warp drives comes from scotsman.com.
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).
Having had one of said people as mathematics instructor; he said it was about 1/3 of the team members who thought it would probably kill us all via igniting the atmosphere, or jettisoning a significant amount of it into space.
Your courageous and selfless spelling corrections have made me a better person.
I did some googling. Apparently the guy did exist and was a real scientist. Burkhard Heim and Heim theory. The theory article seems to explain the stuff behind TFA.
ah ... but how will you see an actual "faster than light" ship...

If videogames have taught me anything it's that these types of dangerous experiments should only be conducted off-world. Like on Mars. What could possibly go wrong there?
abort, retry, fail?
We dinnna think ye could handle it, laddie.
Actually, there is such a theory, and it's 90 years old: Einstein's theory of general relativity. The metric of spacetime (it's curvature, and the thing responsible for what we call gravity) is determined by the energy-stress tensor, and the magnetic field DOES contribute to this tensor. In other words, a magnetic field does create a gravitational field. So does a gravitational field, for that matter. Any energy (and I'm including mass, here) creates a gravitational field.

The problem is we have the most powerful magnet on Earth. It's in Gainesville FL and it doesn't change gravity. The most powerful magnet ever detected was a magnetar of many billions of tesla and that didn't change gravity. We've observed very powerful magnets for years they have never ever slipped into alternate dimensions or changed gravity.
If you read the obliquely mentioned document, and then you pursue the original work by Heim (admittedly you'd have to read German to do that) then you find that what Heim did was simply to complete the work that Einstein started in the 1950's, that is, to derive the universe geometrically, starting with General Relativity and then working quantum mechanics into it, rather than vice versa (which is bloody hard to do.)
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.

So, an early form of the CowboyNeal option?
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.
That's good, but my explanation is more concise. And it has a monkey in it.
*buzzer sound*...WRONG.
"Point A: All motion is relative. If I walk down the asile of a plane, I'm not suddenly walking at 202 mph; I'm walking 2mph in a 200 mph plane, so long as that plane is around me and at a steady flight."
-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.
It takes just a moment and an action to destroy. It takes some time and thought to create.
Hehe,
;D, and IMHO far more interesting. So I'm really glad someone is testing it now!!
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
