- solidhubris, on 10/10/2007, -1/+58This has ramifications for damn near everything...but I can't stop thinking of hoverboards.
- knobtwiddler, on 10/10/2007, -2/+20superconducting gravity bong~!!!
- JD52, on 10/10/2007, -1/+17Blogspam. Here is the link to the origional article.

- 10001110101, on 10/10/2007, -0/+11Interesting.. Makes me think of all those "antigravity quacks" that talked about spinning superconductors/electromagnets.. Maybe they weren't so far off.
- fishandring, on 10/10/2007, -2/+1103/26/2006 - way to stay current. Go digg...
- saleem, on 10/10/2007, -0/+7yeah... great experiment and well done, but they measured the gravitomagnetic (dont digg me down its a real word) field which has never been measured before-- they didnt create anything
- G5Unit91, on 10/10/2007, -1/+7You bozo Mcfly those boards don't work on water...unless u got POWERS!?
- Tankslap, on 10/10/2007, -1/+6Some how we Americans are going to turn this into a weight loss fad.
- dragonworks2050, on 10/10/2007, -0/+5The biggest ramification is the discrepancy between these results and General Relativity. Unified Field Theory, here we come.
- Novagenesis, on 10/10/2007, -0/+5Create gravity in an upward force of 1g, and what happens?
oh yeah, antigravity - robweber, on 10/10/2007, -1/+5I think the actual breakthrough here is the MEASUREMENT of gravity in the magnetic field. Everything around use creates gravity, it just that gravity is such a weak force you need objects as large as the earth and the sun for it to have any effect.
- ToadLeg, on 10/10/2007, -1/+5cue the anti-gravity/UFO conspiracy nuts...
- leftler, on 10/10/2007, -1/+5Think of the ramifications of this technology refined and shrunk down, you could make gravity on a space station or space ship, one of the biggest issues of long term space travel is body deterioration due to being in zero-G. With this technology there is no more need for Stanley Kubrick's spinning space station, and we have something more like the star ship Enterprise gravity.
- Bdog2g2, on 10/10/2007, -0/+3of course gravitomagnetic is a real word. Geordi uses it all the time. Get back to me when they are able to polarize warp fields.
- twrife, on 10/10/2007, -4/+7Time to go colonize Mars.
- pyrates, on 10/10/2007, -0/+2Dupe perhaps? It ends with _2. Just take that away and you see that someone submitted the exact same story, the same wording! And only around 20 minutes earlier. This is beyond a dupe. This is an exact copy. Shame on you Anonymgrl.
Original here:
http://www.digg.com/general_sciences/Researchers_create_gravity_in_lab_experiment - WhiteRaven, on 10/10/2007, -0/+2The "discrepancy" is a difference from what was *expected*. But we have already observed quite a few natural gravitational effects that differ from expectations. In fact, the entire notion of dark matter was invented based on just such a discrepancy. Rather than continuing to assume our established theories are correct, we need to start accepting what the evidence is telling us. We are wrong about the behavior of gravity.
What I love about this is that it blows another big hole is the absurd dark matter hypothesis. "Observations don't match the theory? Invent new factors for which there is no direct evidence to bring reality in line with theory... actually changing the theory isn't acceptable." - gartekh, on 10/10/2007, -3/+5I create gravity all the time...
Everything that has mass does. - inactive, on 10/10/2007, -0/+2No, that already happened in 1985. Try to keep up.
- gizmo490, on 10/10/2007, -0/+2Didn't they create the gravitomagnetic field by spinning the superconductor? Just like you would create an electromagnetic field by spinning a magnet?
- philforhumanity, on 10/10/2007, -0/+2With the current level of technology and antigravity devices, we still can not completely terraform Mars:
http://philforhumanity.com/Terraforming_Mars.html - inactive, on 10/10/2007, -0/+2Who said flying saucers spin?
- cantoral, on 10/10/2007, -0/+2Prof. Tajmar recently sent a paper to a Conference in Australia:
http://arxiv.org/abs/0707.3806
he is very much convinced. - sukimashita, on 10/10/2007, -0/+2For some reason this reminds me of Eugene Podkletnov's Gravity Shielding experiments...
http://en.wikipedia.org/wiki/Eugene_Podkletnov#Podkletnov.27s_gravity_shielding_experiments - inactive, on 10/10/2007, -1/+3is that why flying saucers spins?
- czernel, on 10/10/2007, -0/+2" Whoa, this is heavy "
- cantoral, on 10/10/2007, -0/+2Prof. Tajmar has been zeroing on this historic demonstration for years. If it is what he think it is, this is a door to a modern theory of gravity. Physics is an experimental science.
Applications?
Too soon to tell, but what about a precise gyroscope and a better Global Positioning System? - rowlodge, on 10/10/2007, -0/+2will this download my porn faster?
- WhiteRaven, on 10/10/2007, -0/+2The best thing about quantum gravity is that it will likely blow the stupid "dark matter" theories out of the water. All the computations that the dark matter hypothesis is based on will become irrelevant. The anomalies in galactic movements will probably be explained by a better understanding of how gravity really is generated and propagates rather than dreaming up a new type of mass to explain observed facts. And the fact that this research shows a "stronger than expected force" almost guarantees that this will be the case. It will certainly cut down on the theorized amount of dark matter in the universe.
- kooft, on 10/10/2007, -0/+2Heck, I'd be happy with polarized hull platings.
- EmperorAwesome, on 10/10/2007, -0/+2And open portals to hell.
- Surfrock66, on 10/10/2007, -0/+1Here's the main implication I see. If gravity fields exist like magnetic fields, and a spinning ring produces one, then depending on its orientation it pulls or pushes. Now make a HUGE one (1000 feet in diameter) and set it up to repel upwards...space launches all of a sudden need to fight against a lot less gravity. This is all assuming they can spin the thing faster to make the effect more profound.
- carpespasm, on 10/10/2007, -0/+1meh, gimmie a BFG and some armor packs. i'll clean it up
- inactive, on 10/10/2007, -0/+1I want to see formulas now!
- Tanath, on 10/10/2007, -0/+1No you wont.
- OverThere, on 10/10/2007, -1/+2easy, just spin it in reverse..
/sarcasm... - cantoral, on 10/10/2007, -0/+1Here I propose an idea to explain Tajmar's measurements.
Each electron-hole pair couples very weakly to the gravity field frame attached to the Earth. Since the Earth is rotating it produces a local rotation, this rotation produces a parity violation between the North Hemisphere and the South Hemisphere. The groups that have measured this effect are one in Austria and the other in Australia. The measured asymmetry confirms this parity breakdown.
Now, how can a small gravitomagnetic effect be observed?
There is at least a factor of at most 10^23 to help in the observation, the amount of elementary particles in any macroscopic piece of matter. All that is needed is a coherent response. That is, all the elementary particles have to act like a single macroscopic object. That is what superconductivity could do in these observations.
Coherent matter may be behind amplifying this small gravitomagnetic effect to big measurable parity breaking effects. - masonba2000, on 10/10/2007, -1/+2100 TIMES NORMAL GRAVITY
- Predater, on 10/10/2007, -1/+2Great! Now I can finally get that gravity gun I always wanted!!!
- frosted, on 10/10/2007, -0/+1Old news.
Men walked on the moon too, get over it. - elementop, on 10/10/2007, -0/+1I thought it was 9.8 m/s^2?
- inactive, on 10/10/2007, -1/+2For all of you talking about "gimmie anti-gravity" you obviously don't understand the implication. If you can create GRAVITY at a greater strength than 11 m/s acceleration above any object it will effectively float as the field above it will be stronger than the pull of the earth. In short, if you have a gravity machine, you basically have an anti-gravity machine too.
- mstachiw, on 10/10/2007, -0/+1want to make gravity... try Taco Bell or Papa John's.
- gthrank, on 10/10/2007, -0/+1Surprised this isn't covered wider in the scientific press. The presentations were done in 2006. What did the peer reviews say?
- dudad, on 10/10/2007, -0/+1"If confirmed, this would be a major breakthrough." It's currently a year later than this was published...
- WhiteRaven, on 10/10/2007, -0/+1No, you don't. Not really. Sure, you could create a *region* where gravity is effectively zero but only within a structure. The machinery itself is still within the earth's gravity and gravity can *only* attract. So, you can mount a gravity machine on the ceiling of a room and float between it and the floor but it would not be possible to mount a machine on a vehicle and make the vehicle fly. There simply no force that would be pulling up on the resulting craft. In fact, the only thing the craft would be able to do is cling to the ground harder.
What we need to create "anti-gravity" is a way to insulate things from the effect of gravity... and this ain't it. - df12, on 10/10/2007, -0/+1The very large discrepancy would seem to imply what is being measured is something other than what they believe. Especially given that GR has been precisely verified in every other experiment ever run. Also, the fact that this discovery is over a year old and we haven't heard anything in the interim would seem to indicate something other than reproducibility...
- kellymahan, on 10/10/2007, -0/+1EM fields can repel, gravity cannot. You could levitate anything provided the gravity generator was already higher, and has something holding the generator up in place. Simply attaching it to the top of the craft has a net negative(towards the center of the earth) effect on the craft. The only thing i could see making this useful is if there was a way to control airflow to allowed the craft to be lifted. Or simply create so much pressure around the craft that it becomes lighter than the air around it (think about that one for a sec)
- df12, on 10/10/2007, -0/+1Good old Richard C. Hoagland.... Nice to see his insanity hasn't yet driven him to do something terminal.
