Dont get too excited its just a question :P but how far away do you think something llike this is? is there any research on antigravity going on at the moment?

sorry, im so bored today :S



Yes- it's called General Relativity theory. If you can make anti-gravity you can also make a warp drive and create wormholes through spacetime like in the movie "Timeline". All you need is a little negative energy (well, a lot actually, enough to cancel out the mass of the Earth). Should be ready for market in a few months.

The easiest way to get antigravity is to suspend a massive weight above an area on the surface of the earth. That weight will counteract the earth's gravity if it's massive enough, and there will be a region of microgravity beneath it. You'd need degenerate matter (i.e. neutronium) to make the weight dense enough, and it would wreak havoc with local weather and tides, but it would work.

Another way is to accelerate a lot of mass to very near lightspeed in a ring above an area; its mass goes up (relativistic mass expansion) and you get that ultradense mass without neutronium. Again, some engineering problems remain.

A much easier way is just to fly in a plane doing a zero-G parabola. You can get something like 2 minutes in the right sort of aircraft.

To me, antigravity's not too much fun. Unless you're near walls, you just sit there with no way to move yourself around. (Most people were not born with rockets or fans.)

My understanding (very small with physics) is that the most effective (read: not easy) way is not to fight gravity, but to cancel it out below you. Think I read a few months ago that there was not only research in this area, but testing of prototypes using some superconduction and .... hell if I remember what it's called.

Any physicians in the house? :P

Well, I can see we might have at least a few different opinions here between Kallend, billvon and myself, but I don't think you can simply cancel out gravity with a magnetic field or any sort of magnetic shielding. I just dont' think it works that way. I personally believe mass reshapes space-time which wouldn't allow for any sort of real shielding any more than you can shield a compass from a powerful magnet by putting another magnet near it. The lines of magnetic force being somewhat analogous to the curving of space-time around mass.

There was an experiment done a while back where some guy was claiming to have "cut off" gravity with some sort of magnetic bottle, but I think analysis showed he was just levitating things in a magnetic field -- a live frog was one such object. And I think that's why a lot of folks were fooled because one doesn't normally think of frogs as being particularly magnetic, but with the levels of magnetism involved -- yes -- it was.

There have been LOTS of hoaxes in the area of anti-gravity "research" and the US government has been fooled several times by folks looking for grant money. Some folks claim wacky things like the continuation of Tesla's work, but again . . . more sparks than reality. (BTW, I'd always hoped that one day Geordi was going to make a reference to the Warp Coils being a lot like Tesla coils, but I guess the guys in the original series blew that when they invented Zefram Cochrane, the inventor of the warp drive. I still think it's a derivative work -- oh well).

Well, this one wasn't a hoax, persay. It may not work, but not a hoax. It was in a Popular Science last time I heard anything about it. I understand the basics of mass reshaping existence theory. The problem, as I understand it, is that it can't handle quantum physics. (disclaimer: I don't claim to understand quantum theory, but as far as I'm concerned, anyone who says they do understands it less than me) So I guess my question is do you think gravity can be redirected or reshaped? If gravity is another form of energy, why can't it be changed, like light, radiation, etc?

The theory that caught my eye was one stating there are 10-12 dimensions to the universe. I suppose if we say time, or expanding three dimensions, is the fourth, then maybe the fifth would create the so-called multiverse. Expanding time and creating infinite numbers of alternate universes. You could argue cartoons are three dimensional, requiring time to function while not possessing our common third, depth. It's interesting, if nothing else.

You should be able to complete that little project in one, two at the most, weekends.:P

Since no-one has been able to establish a unification between electromagnetism and gravity, it follows that any anti-gravity idea using magnetic fields is not based on science.

My answer was real. There IS research in the area of spacetime distortion going on in theoretical physics by respectable physicists. Theoretical requirements HAVE been established for antigravity, wormholes and warp drives. General Relativity does not forbid any of these, nor does any tested theory forbid time travel. Since time travel violates causality, and wormholes allow time travel, and wormholes require local negative energy density to keep them open, maybe negative energy density is forbidden. No-one has been able to create it yet, anyhow, but that could just be an engineering problem:P

If you can create an appropriate distortion in spacetime you can pinch off a volume of it and create a new universe. Maybe some high school kid did this 15 billion years ago for a science fair project, and inadvertantly created our universe.

In my spare time I'm a physics professor.

a wormhole has been created before, hasnt it? Albeit, a very very tiny one. to create one that a human could pass through is way beyond our abilities at this time. (i think) B| Besides, i think if somebody was actually stupid enough to try to go through a wormhole, they would get ripped to pieces.

As far as I can remember, no one at Nijmegen where the diamagnetic levitation of frogs was performed, ever claimed to have found anti-gravity. Whilst the the levitating frog experiment is not anti-gravity in the true sense, it is most definately real and is based on well known physical laws. Surely you do not dispute this?

>have you experienced it bill?

What? Being under a ring of relativistic mass? No. Doing zero-G in an airplane? We used to do that with our King Air. We got 10-15 seconds, which was enough time to jump from one end of the cabin to the other without touching the ground. Was very cool. Then the DZO found out about it and (of course) put an end to it.

Agreed. To me, using such a magnetic gradient to levitate something is akin to using a big fan - it's not so much antigravity as generating a force that can oppose gravity in a small volume.

I do a diamagnetic levitation for my class every semester. Who said I disputed magnetic levitation. The point is that magnetic levitation is NOT anti-gravity, nor is any other idea based on electro-magnetism.
