no good can come from this.
pretty soon they're going to be making anti-matter bombs. that'd be wild.

umm, antimatter particles have been created before in particle accelerators.
its the storage of anti-matter which is the problem.

We will have our klingon friends help us though. Besides, the borg are the bigger threat...we must prepare!
You guys think jumpsuits are dorky.. but look at what sailors wear now. You think those hats and ties are cool?
I think we have a long way to go before any anti-matter bombs just yet, 50,000 anti hydrogen atoms which it has taken them around two months to produce will give out around 0.03J if it anihillated with normal matter.
You realize that these dinky flashes are from the anihilation of a single atom, right?
I call dibs on the first antimatter powered car.
Storage is no problem in an anti matter jar.
I wonder if anitmatter has normal gravity or anti gravity.

I take it you didn't read the article.
They created antiatoms, the antimatter equivalent of elemental hydrogen. They called it anti-hydrogen, composed of an antiproton nucleus (negative charge) and positron shell (positive charge). As I understand it, this has never been done before.
It's an interesting milestone but it doesn't have any real near term impact on our daily lives.

Normal gravity.
Negative matter would have antigravity and fall up
Particle weirdness:
If you had a particle of negative matter and "regular" matter, lets say protons, one would attract and one would repel the other, causing the pair to zip off into the universe at ever increasing speeds.

-------------------------
Ok were talking photon and negative photon, I presume. I can see them zipping off if they were in close proximity at increasing speeds, but as the distance grows what relationship is there to the forces repelling them to keep the speed increasing. If it were to decrease at the square of the distance, something I could easily guess might be the case, you might think there would be some sort of limit to the speed. There would also be the light speed limit, no? I also presume that they would speed off in opposite directions, but that due to the curvature of space they would eventually be heading straight for each other. What happens when they get half way their? Would they come to equilibrium there or would momentum cause them to bump into each other and make a return trip? Ever get the feeling that everything is a vibration?

They would have normal gravity, unless gravity is in fact quantized, and antimatter reacts with anti-gravitons (edit: anti-gravitons don't exist)... Then it's all messed.
Negative matter? WTF? It'd have a negative mass... right...
About the two particles just zipping along by themselves, um, does no one see the conservation of mass/energy problem there?
Anti-photons? Huh? Care to explain how you can have a particle with the opposite charge of a chargeless photon?
Now about the bomb thing. An M-AM bomb is just a very very efficent fusion or fission bomb. The source of the blast is the same in either bomb; the conversion of matter into energy. Fusion is more efficent than fission (on an energy/mass basis at least), and M-AM is theoretically 100% efficient.

Lemme see,
Negative matter is one of those postulated exotics. It has never been seen, but it's existance is required in some cosmological models, or at least there is no known physical prohibition.
Cool stuff.
Hello M!
I was thinking of massive particles for my example, because mass is related to gravity. Photons can feel gravity in the sense that they follow curved space, but do not generate gravity themselves.
Meebe this will clear this up.. In this example a proton (could be any other massive particle you like) and a negative proton are placed close enough so each can feel the other's gravity. Cant be too close in this case, because a negative proton has a positive charge and repells the garden variety one. Now the "regular" proton senses the mass of the negative one. It falls towards it. The negative gravity of the negative particle senses the regular proton. It falls AWAY from it. One trys to capture the other and the other trys to escape. Because the force of gravity in this case is identicle, neither particle moves in respect to the other, but it does to the rest of the universe. It is a PushmePullu. Otherwise undisturbed, it will continue to accelerate, ever approaching the speed of light.
It violates no conservation of energy rules, because remember that classically, gravity is an acceleration. How much energy does the moon use up falling around the earth? What is it's means of propulsion? None. Same here.
Silverpig, Moonbeam is correct in saying there are antiphotons. A cornerstone of the understanding of particles calls for every particle to have an antiparticle. Photons, neutrons, everything.
Moonbeam has a knack for picking out the oddballs though
OK, I will give this a try. An antiparticle can be considered an "normal" particle travelling backwards in time. If an antiphoton has not interacted, it behaves in a different way than one that does. It's kinda of complicated, because it involves some abstract concepts that are not easy to give here. Look it up if you dont believe me
For most purposes, a photon is considered it's own antiparticle.
Oh, to really make your head spin, you could have an negative antiparticle

An AM bomb would be much, much more powerful than nuclear bombs. Think about it, annihilating anti-matter produces pure energy, more powerful than fusion, way more powerful than fission.
