well,the wave front would propogate faster than light speed sinnce gravity waves can propogate fater then light.ill look that up and get back to you.i think if you could form a bose einstien condensate areound an area.you could form a fieild in front of an object.like let me refrace.,you could contract scace infront and expand sace in back.let me get some links.hold on

The Speed of Gravity – What the Experiments Say

Abstract.

Standard experimental techniques exist to determine the propagation speed of forces. When we apply these techniques to gravity, they all yield propagation speeds too great to measure, substantially faster than lightspeed. This is because gravity, in contrast to light, has no detectable aberration or propagation delay for its action, even for cases (such as binary pulsars) where sources of gravity accelerate significantly during the light time from source to target. By contrast, the finite propagation speed of light causes radiation pressure forces to have a non-radial component causing orbits to decay (the “Poynting-Robertson effect”); but gravity has no counterpart force proportional to to first order. General relativity (GR) explains these features by suggesting that gravitation (unlike electromagnetic forces) is a pure geometric effect of curved space-time, not a force of nature that propagates. Gravitational radiation, which surely does propagate at lightspeed but is a fifth order effect in , is too small to play a role in explaining this difference in behavior between gravity and ordinary forces of nature. Problems with the causality principle also exist for GR in this connection, such as explaining how the external fields between binary black holes manage to continually update without benefit of communication with the masses hidden behind event horizons. These causality problems would be solved without any change to the mathematical formalism of GR, but only to its interpretation, if gravity is once again taken to be a propagating force of nature in flat space-time with the propagation speed indicated by observational evidence and experiments: not less than 2x1010 c. Such a change of perspective requires no change in the assumed character of gravitational radiation or its lightspeed propagation. Although faster-than-light force propagation speeds do violate Einstein special relativity (SR), they are in accord with Lorentzian relativity, which has never been experimentally distinguished from SR—at least, not in favor of SR. Indeed, far from upsetting much of current physics, the main changes induced by this new perspective are beneficial to areas where physics has been struggling, such as explaining experimental evidence for non-locality in quantum physics, the dark matter issue in cosmology, and the possible unification of forces. Recognition of a faster-than-lightspeed propagation of gravity, as indicated by all existing experimental evidence, may be the key to taking conventional physics to the next plateau.

The speed of gravity has been measured for the first time. The landmark experiment shows that it travels at the speed of light, meaning that Einstein's general theory of relativity has passed another test with flying colours.

Ed Fomalont of the National Radio Astronomy Observatory in Charlottesville, Virginia, and Sergei Kopeikin of the University of Missouri in Columbia made the measurement, with the help of the planet Jupiter.

"We became the first two people to know the speed of gravity, one of the fundamental constants of nature," the scientists say, in an article in New Scientist print edition. One important consequence of the result is that it places constraints on theories of "brane worlds", which suggest the Universe has more spatial dimensions than the familiar three.

John Baez, a physicist from the University of California at Riverside, comments: "Einstein wins yet again." He adds that any other result would have come as a shock.

You can read Fomalont and Kopeikin's account of their unique experiment in an exclusive, full-length feature in the next issue of New Scientist print edition, on sale from 9 January.

Isaac Newton thought the influence of gravity was instantaneous, but Einstein assumed it travelled at the speed of light and built this into his 1915 general theory of relativity.

Light-speed gravity means that if the Sun suddenly disappeared from the centre of the Solar System, the Earth would remain in orbit for about 8.3 minutes - the time it takes light to travel from the Sun to the Earth. Then, suddenly feeling no gravity, Earth would shoot off into space in a straight line.

But the assumption of light-speed gravity has come under pressure from brane world theories, which suggest there are extra spatial dimensions rolled up very small. Gravity could take a short cut through these extra dimensions and so appear to travel faster than the speed of light - without violating the equations of general relativity.

But how can you measure the speed of gravity? One way would be to detect gravitational waves, little ripples in space-time that propagate out from accelerating masses. But no one has yet managed to do this.

Kopeikin found another way. He reworked the equations of general relativity to express the gravitational field of a moving body in terms of its mass, velocity and the speed of gravity. If you could measure the gravitational field of Jupiter, while knowing its mass and velocity, you could work out the speed of gravity.

Bending waves
The opportunity to do this arose in September 2002, when Jupiter passed in front of a quasar that emits bright radio waves. Fomalont and Kopeikin combined observations from a series of radio telescopes across the Earth to measure the apparent change in the quasar's position as the gravitational field of Jupiter bent the passing radio waves.

From that they worked out that gravity does move at the same speed as light. Their actual figure was 0.95 times light speed, but with a large error margin of plus or minus 0.25.

Their result, announced on Tuesday at a meeting of the American Astronomical Society meeting in Seattle, should help narrow down the possible number of extra dimensions and their sizes.

But experts say the indirect evidence that gravity propagates at the speed of light was already overwhelming. "It would be revolutionary if gravity were measured not to propagate at the speed of light - we were virtually certain that it must," says Lawrence Krauss of Case Western Reserve University in Cleveland, Ohio.

The Alcubierre Metric is a curious mathematical result that has nothing to do with the real world. Here's a simpler example of the same thing:

Say you have a square piece of plywood with a surface area of 9 centimeters. What is the length of each side?

Well, if the square's surface area is 9 centimeters, then each side must be square root of 9 centimeters long. The problem occurs in that 9 has two square roots, 3 and -3 because 3 * 3 = 9 and also -3 * -3 = 9.

It is meaningless to say that the square in question has sides of length -3.

Alcubierre's theoretical model is the same as the theoretical negative solution to the above problem which is meaningless except as a mathematical curiosity.

This theme repeats in the concept of the Tachyon (faster than light particle) which is another mathematical curiosity that has nothing to do with reality. If tachyons existed, they would have a mass of square root of -1, which is meaningless (actually, it would be square root of -1 times some coefficient, but that's not important here).

Besides, if someone was gonna invent Warp Drive, it would be a Cuban, not a Mexican.  :wink:

Actually, Kopeikin's and Fomalont's results have been called into question. Most physicists do believe General Relativity is correct and gravitational radiation does propagate at the speed of light, but they don't think Kopeikin and Fomalont proved it.

Nope. Where are you getting this. Information, so far as we know, cannot travel faster than light, and it has never been observed to do so.

Some things CAN travel faster than light, but they do not carry information and so do not violate causality.

For example, it is possible for a wave, or more precisely, an interference pattern formed by waves to travel faster than light. Here's a thought experiment that demonstrates it.

Ever watch a football stadium full of people doing "The Wave"? It happens when one vertical file of bleachers suddenly stands, then sits. When that group of people sits, the next file to their right stands, then sits. Repeat this for each file and from a distance you can observe a wave propagating around the stadium.

This type of wave can never exceed the speed of light because the fundamental speed limit prevents the file to the right receiving faster than c the information that the prior file just sat and now it's next file's turn.

However, imagine that you give a very accurate watch to each person in the stadium and instruct them to stand at a specific time instead of when they notice that the prior file has sat down again.

If each person stands and sits at a specific time rather than when they observe their neighbor siting, then you can adjust the timing such that the wave will propagate faster than the speed of light.

However, causality is not violated by this because even though the wave propagates faster than c, it carries an information theoretical entropy of zero, and no information is transmitted. This is because the wave is timed and not strictly propagated.

Another example of something traveling faster than light is the dot made by a laser beam. If the distance from the laser and the plane on which the dot appears, and if the angular velocity of the laser are high enough, then the dot will move along the plane of projection faster than c, but again, no information can be sent faster than c this way.

Maybe not information... but rumors sure travel faster than light. :smile:
