I'm disappointed that this thread wasn't started by Tim.
Red matter?
so are we still looking for "Nothing"?
Antimatter are the things that do not matter. Such as, well, "size".
If anti-matter really matters why do we never hear about uncle matter?
I look forward to ask scientists what's the matter.
Use an antimatter-of-fact tone.

What are the practical applications of antimatter?

I presume it would be the obvious: causing a reaction with matter to produce a release of energy.

But can it be done economically? After all, positrons have very little mass.

No idea...but besides this one quality (producing energy when close to matter) anti-matter is identical to matter so what other practical reason could their be for capturing some?

Hard to say. I'm not conversant in anti-physics or anti-chemistry.

I would say so. Imagine you have a bunch of stuff that matters, like a small mole hill of unpaid bills. Release the antimatter, and it won't matter any more.

I thought it took more energy to make then it would put out.

Even if true if it can be captured and stored it may be useful for energy storage perhaps. After all no energy storage method is 100% efficient.

Yes. On the other hand, anti-matter is a hell of a battery.
Huh. I looked this up. Positrons seem to be just one form of anti-matter one that occurs naturally (though not on earth). If they could get it to produce the energy advertised then I can see how it would be handy.

Still, being multiplied by the speed of light squared means very little mass in can lead to rather big results...

To be sure. But 160 femtojoules isn't so hot. Even if you annihilate them ten trillion at a time, you're still going to produce enough energy to create a harmless puff.
Now, if they can derive a means of production for antiprotons, that might be interesting.
from article:
Quote
In order to harness the energy of positrons, Weber listed three problems that must be overcome.
"We need to be able to generate many positrons; we need a vacuum container to store them in; and then we must convert their annihilation power into something that drives an engine or turns on the lights. Right now we are focusing on the storage problem."
What's the military potential of this?

You could destroy a city with just a few grams.
I don't want to rain in citizen k's parade, but we have had antimatter for decades now...
You all know we have positron emission treatments, right?
And you DO know that Positrons are simply the anti-matter equivalents of electrons, right?
In other words, when the doctors say they're doing positronic stuff, they're simply throwing antimatter at you (usually into your brain) in order to destroy the problematic tissues that are made of matter....

No clue. If they manage to quantify antimatter, several laws of physics are going to have to be rewritten anyway. I wonder what kind of, if any, reaction would occur, since all of our energy sources thus far rely on the law of conservation of energy; all our energy is achieved through
manipulation of matter; not destruction of matter. If LCE holds true, then we'd have to find a way to manually destroy equal amounts of both matter and antimatter simultaneously, but since that would be a new reaction, who the hell knows what kind of energy output you would achieve?

Hmm, something I noticed after finally reading through the article- I didn't realize we had quantified the energy output already- if that much antimatter is being held at the galactic center, what's the mechanism that's keeping it there and keeping it from leaking into everything else? If it's the concentration of stars functioning as a huge plasma trap, why couldn't we extract the positrons from our own star?

Yeah, but a few grams is also 300 septillion positrons, which at the current rate of generation would take 27 million years.

Actually, positron emission tomography is a diagnostic technique. The positrons aren't actually fired into your body. Rather, you are injected with a radionuclide which produces positrons as it decays. A sensor rig detects gamma rays produced by the reaction and provides a nice 3D image of your body.
To use positrons to annihilate selected tissues is far outside the realm of possibility right now, and is far outside the realm of common sense in any event. Even the annihilation of a single red blood cell would generate an explosion of roughly a kiloton.
