Is antimatter the key to anti-gravity ?

Scientists at CERN are experimenting to determine if an antimatter object would actually fall upwards.

The radical concept could lead to the discovery of true anti-gravity, a technology that has been a staple of science fiction for years. Researchers will be attempting to determine whether or not antimatter, which is effectively the mirror image of conventional matter, is repelled by gravity and falls upwards instead of down. The way in which antimatter responds to gravity has to date remained a mystery.

"In the course of all the experiments, we release (the antihydrogen atoms) and look for their annihilation," said spokesperson Jeffrey Hangst. "We've gone through those data to see if we can see any influence of gravity on the positions at which they annihilate - looking for atoms to fall for the short amount of time they exist before they hit the wall."

"Researchers at Cern in Switzerland have tested a novel way to find out if antimatter is the source of a force termed "antigravity"."

Antimatter is not key to anti-gravity, it is the key to anti matterialisam. :-)

I once sat next to a young man on a plane who carried on a very interesting conversation with me. He was going to meet his mentor at Los Alamos, where he was starting to work. He said that she said that "if we can imagine it, we now have the technology to make it happen." We talked about time-travel. But we could just have easily talked about anti-gravity. Talking about it is one thing, having reliably functioning devices is another. I don't want to ridicule you for your beliefs, since I also form perceptions based on my beliefs. I believe that no human agency has operating antigravity devices... [More]

Don't know what a modern lab has to do with long dead greeks. But, maybe you should have read both of my posts. really, you have to think past what I write, Danilost. Seems you just don't do that.

I believe that there is already invented antigravity devices and that they are currently being used somewhere in the world. [/size] Talking about it is one thing, having reliably functioning devices is another. I don't want to ridicule you for your beliefs, since I also form perceptions based on my beliefs. I believe that no human agency has operating antigravity devices. I believe this because the only theoretical way that antigravity could operate is by something that has a negative gravitational mass. In the last 80 years of high energy collider experiments, advanced optical, X-ray, radio t... [More]

The national lab is learning how to put things together that we don't currently know how to put together. When they figuare it out, they give it to the government who work out some of the bugs and then give toi industry to produce. For instance, before ww2 the united states military were the first ones to play with jets. But, we didn't use them during the war. Because we dihdn't feel the were ready. Toward the end of the war, the germans ptoduced the first line of jets... [More]

Doesn't anti-matter cause matter and itself to blink out of existence if they come into contact? Not very practical or safe to use on a matter-planet filled with matter-people. They do much worse than that; they annihilate each other in a burst of gamma radiation.

We have antigravity devices now: rockets, helicopters, hot air and lighter than air balloons, good ol' mountain climbing equipment. What I think is being dreamt is something that lifts us against gravity without needing a lot of work.

There is a way to test for truth. It isn't rational. But it is pretty much fool-proof. So you go on with your impression. I will certainly go on with my own. And none of this really matters in the end.
