[QUOTE=CNiall;21388487]Well, yeah, but it'd be more likely for it to come into contact with whatever was firing it first and annihilate anyway. Alternatively, fire it in a vacuum -- but then there's still the issue of actually, y'know, [i]firing[/i] it.[/QUOTE] You could build special containers that are able to hold antimatter but would break apart when it gets close enough to the target. I think using antimatter as a weapon would be a terrible idea anyway. You'd have to keep enough of it on hand to obliterate your enemy and that would be more than enough to obliterate yourself if the container fails or becomes damaged.

What happens if you ejaculate onto antimatter?
[QUOTE=d3450;21390528]What happens if you ejaculate onto antimatter?[/QUOTE] Death happens.
I wonder if a microgram of anti-matter costs more than the accelerators, engineers, power plants and uranium to produce it.
[QUOTE=Nikita;21391280]I wonder if a microgram of anti-matter costs more than the accelerators, engineers, power plants and uranium to produce it.[/QUOTE] Probably.
@CNiall Your avatar is Aleph null isn't it? Could you explain what exactly that is? I looked it up once but didn't understand it.
[QUOTE=Doctor_Communism;21376144]Could anti-mater be produced by matter being flipped along a fourth dimensional axis?[/QUOTE] What does the fourth dimension have to do with antimatter?
[QUOTE=xxxkiller;21392502]What does the fourth dimension have to do with antimatter?[/QUOTE] Nothing.
I remember watching a show saying that a piece of antimatter the size of a a paper clip can destroy New York city. Is that correct?
[QUOTE=Kyle902;21392788]I remember watching a show saying that a piece of antimatter the size of a a paper clip can destroy New York city. Is that correct?[/QUOTE] Yep. And a metric ton can power the entire Earth for a year.
[QUOTE=Quidsy the Squidsy;21388424]Wouldn't firing antimatter at things as a weapon fail, due to it instantly colliding with air particles and blowing up?[/QUOTE] You could suspend it in some sort of magnetic casing that shatters on impact. That would be the only way an AM weapon would work without blowing your gun up. Unless you used it in space weapons....... [editline]04:07PM[/editline] And I'm pretty sure a few atoms of the stuff in suspension would be more then enough to completely vaporize a human.
Heh, if people really manage to get enough antimatter to make weapons and stuff, I doubt it's going to be made to be fired like a gun. A bomb is more possible, I mean 0.5 kg, which is the weight of a hand grenade can blow up a whole city (23 megaton?)

For example it would take shitloads more to destroy LA then it would take to destroy say... London. This is due to the fact that most structures in LA are designed to be VERY resistant to damage.
[QUOTE=Raxas;21392784]Nothing.[/QUOTE] It was a rhetorical question implying that he had no idea how dimensions work in physics.
"One researcher of the CERN laboratories, which produces antimatter regularly, said: If we could assemble all of the antimatter we've ever made at CERN and annihilate it with matter, we would have enough energy to light a single electric light bulb for a few minutes."
[QUOTE=Cogniscente;21376306]The magnetivity requires energy input law of conversation of energy etc[/QUOTE] Yes, but the energy required to negate the collision of the antimatter would be negligible, no?
Rate agree if you just scrolled down and rated informative without reading more than the first few sentences like me

[QUOTE=Lord_Skellig;21391739]@CNiall Your avatar is Aleph null isn't it? Could you explain what exactly that is? I looked it up once but didn't understand it.[/QUOTE] Yep, it's aleph null. The shortest and simplest answer is that there are different sizes of infinity and that aleph null is the smallest with there being 'aleph null many' natural numbers. If you want a longer explanation, I'll do my best while tired and hurrying to get to bed: Every set (a group of mathematical objects) has a size -- obviously. This is referred to as cardinality, e.g. (1,2,3) has cardinality 3 as does (red,blue,yellow). If you want to look at the cardinality of infinite sets (such as any number system you care to name), however, you can't outright compare the sizes of them since there are infinitely many items in the set. But if you can prove that a bijection exists between two sets (i.e. for each element of one set there is one and only one element of the other that corresponds to it) then they must have the same cardinality. Therefore you can see that there are the same number of natural numbers (the integers above zero: 1, 2, 3, 4...) as there are integers, rational numbers, odd numbers, primes, whatever. For example, the even numbers: 1 - 2 2 - 4 3 - 6 4 - 8 etc. You can do the same for the rational numbers if you do things a little oddly and arrange them into a table, moving through it diagonally and ignoring duplicate fractions and adding 0 to the start and each fraction's negative after the positive (I'd find a diagram but I'm too tired). Since these all have the same cardinality, these were said to have cardinality aleph null. Now consider the real numbers: could we put them into a bijection with the natural numbers? No, because of Cantor's Diagonal Argument (for simplicity here using 0s and 1s -- it still proves what it has to): If you make an infinitely long list of all decimal numbers between 0 and 1 containing only 0 and 1 and ignore the starting '0.' -- for example, 0010001 and 110101010101 would be in this list) then read along the longest diagonal from top left to bottom right and change the number (0 to 1, 1 to 0) you can find a real number that isn't in the list and so a bijection can't be made. Thus while there are infinitely many natural and real numbers there are more reals -- the real numbers have a cardinality larger than aleph null (which is, conveniently, aleph one). As it happens the two aleph numbers are related: aleph one = 2^(aleph null). Why isn't overly complex but I'm really tired now so I don't want to explain it now -- hell, I don't even know if my post made much sense at all.

I feel a little bit smarter now.
[QUOTE=BaconDioxide;21372951]Yeah. Say if you had two molecules, one of hydrogen and the other of antihydrogen, they'd just sit there. Unless you take Van der Waals forces into account, but that's more chemistry.[/QUOTE] Depends on the distance between them. The reason you can't push your hand through an object is because of the electrostatic repulsion between the atoms in your hand and the atoms in the object in question. At a large distance matter is uncharged for the most part. At small distances those charges rule and everything that happens is because of them. Sure, an anti-hydrogen atom itself may be uncharged as a whole (because the 'anti-protons' would be negatively charged, and the positrons positively charged), but if you place a regular hydrogen atom next to it and it's close enough the electron cloud of the atom and the positron cloud of the anti-atom would attract each other together. [QUOTE=petieng;21375779]What? There is no evidence of this.[/QUOTE] What he said. There seems to be baryon asymmetry in the universe. If the universe had come into existence with equal amounts of matter and anti-matter EVERYTHING would have annihilated with its anti-matter equivalent and the universe would just be an ocean of photons. And, as any sensible person can deduce, this is DEFINITELY not the case. Matter exists. The universe isn't an endless ocean of photons and nothing else. Most scientists accept that there must have been baryon asymmetry in the first few moments of the universes existence, yet to date, nobody knows why. There are the suggestions of 'anti-matter dominated regions of space', but that's been determined as unlikely as eventually you'd expect some matter to wander into such areas and we'd detect gamma ray bursts from the resulting explosions. However, that said, it can't be entirely ruled out.
Yeah, the existence of the odd antimatter star is [I]possible[/I] but very unlikely. Any nearby antimatter star would be quite easy to spot, as stungle said. Also, antimatter stars would emit antimatter radiation. Their solar wind would be composed of anti-particles. Because of this, their solar wind would annihilate with the surrounding interstellar medium, nebula and molecular clouds making them very noticeable.
there's a lot of money floating above my head so close yet so far away :frown:

Antimatter: Cool but useless.
Everything in this damn world is a mystery.
Interesting stuff, but where's your sources?
