boy is to girl as matter is to antimatter?!

Yes, anti-matter or better called mirror matter does exist. Some radioactive material decays into both matter and antimatter. The normal matter particles do whatever they do, and the anti matter particles formed hit some matter and they are both destroyed in a flash of gamma ray energy. As for large amounts of antimatter existing somewhere, I think it would have to be beyond the edge of this matter universe. Except for an interesting group of objects I have my suspicions about. Quasars. You know what a normal spiral galaxy looks like. At the edges of the observable universe are Quasars, only just recently imaged in high resolution. They are extremely bright objects. Keep in mind the edge of the observable universe is also a long time ago, billions of years. To my knowledge, spiral galaxies all have a black hole at the centre. Quasars have what appears to be a normal galaxy surrounding the super bright object at its core. I have a suspicion that there could be an antimatter blackhole in the core. I am not a scientist, just another person that like to ponder things like you do. I think that there are no Quasars nearer us because all the material in the core was evaporated by annihilation with the infalling matter a long time ago. Which leaves me to wonder, if an anti matter galactic core gets down to a certain size, the minimum required to maintain a singularity, will it explode catastrophically? Is there a signature in the spectrum of light from them that may indicate whether annihilation is happening or not? If there was a lump of antimatter floating through space, I think it would be constantly flashing in the gamma spectrum, due to impacts from gases, and molecules and other sub-atomic particles in space. Maybe it is the dark matter, it can only exists as lumps here and there because every time it touches matter, you know what happens. I wish I knew more too, wouldn't it be good to be right in the know.

Wow, this discussion was made one year ago. Cool About your discussion, I think that the "boy is to girl as matter is to antimatter" analogy is not exactly the best way to put it. Yes, they are all opposites, but male and females don't destroy each other. What happens if you put hot and cold together? You get warm. If you put good and evil together, well, no one knows, because there is no such thing as good and evil. However, putting a male and female together (assuming you mean humans) are not opposites as they are the same species, and when together they create, not destroy. Is one gender a negative, the other positive? No. In mathematics equal negatives and positives (e.g. -5, +5) will destroy each other and you will end up with nothing, equality, 0. So, in a way, male and females are the opposite of opposition. Yes, antimatter already exists. Didn't you know? http://en.wikipedia.org/wiki/Anti_matter There it talks about antimatter, what it is, and how it is already being used. Well, it is not exactly being used, as it is extremely costly. There is existence of antimatter, not just a possibility, it already existed, it is simply not being used very much.

Haha nice! Antimatter does exist. When matter and antimatter join then it is like a whole being filled and there is not more of that matter. Instead the matter is converted to a form of pure energy. I wouldn't say a boy and girl are like matter and antimatter though. They don't vanish and form pure energy during interactions. This is how I understood it in physics class anyways. Good question.

Well, in my opinion, male and female are not opposite, but complementary. Theoretically, when matter and anti-matter meet, they annihilate each-other, with a great energy emission. I think anti-matter can exist, there are many things in sub-atomic physics or in quantum physics that we don't know or don't understand yet.

Mmm, probably... That is exactly the reason why scientist are building atom smashers for them to know what exactly happened in the big bang theory and thus, discovering new things including that. But, i guess, atom smashers are very dangerous because they are making two atoms smashed together in a light speed and it can create a black hole... nice post maris.. hehehehe...
