Antimatter Peek-a-boo

So I was at work the other day, contemplating some things I'd heard while watching that crazy-awesome science show with Morgan Freeman, and had a realization.

Big Bang, right? But theoretically, that event should've made an equal amount of matter and antimatter. We're all, "lolwut, where's teh antimatterz?", and the universe just kinda shrugs at us and says, "Figure it out, silly primates."

So we have this conundrum, which we gleefully ignore because we don't really have the tools yet to answer it.

Then we have the cosmological cons- I mean, dark matter/energy (did you see what I did there?). This stuff that is pushing the universe apart to counteract the power of gravity, with one little problem - we can't freakin' see it.

And so I say... oh really. Isn't that interesting?

Light, right? Photons and stuff. Electrons shifting through the various shells release very specific amounts of electromagnetic radiation, sometimes visible to us, in discrete energy amounts. Which could lead to a fun discussion of quantum mechanics, but not today. Okay, so electrons bouncing around causes light, which is visible to us. Yay.

Antimatter is, when it comes down to it, "just like matter," just with reversed polarity (somewhere, LeVar Burton screams for the pain to stop) - by which I mean, you've got a probability cloud of positrons orbiting around a nucleus of... antiprotons? Man, somebody's gotta come up with a better name. Right, so anyway, the stuff is basically the same, just with the signs reversed.

Except then we get into an interesting discussion regarding the interaction between matter and energy. E = MC^2, or so goes the simplified version of Einstein's most well-known theory. Energy and matter are interchangeable. Which would seem to indicate that, perhaps, just maybe, antimatter has its own thing going on - anti-energy.

But that's kind of tangential, and is getting a bit ahead of ourselves (that concept plays into how I envision an Alcubierre drive functioning, but I'll save that for later).

The important thing is antimatter chemical reactions and such. In normal matter, when electrons shift down-shell, they release energy, some of which we can see as light (which we discussed earlier). However, we have no idea (I don't think) of what happens when antimatter undergoes similar effects - do positrons shift up-shell when electrons would down-shift? Do they down-shift, too, but release anti-energy?

I propose that, regardless of what it's doing or how it's doing it, antimatter is effectively invisible to the human eye. By virtue of how light works, it seems sensible to me to say that such a thing as an anti-photon could exist, and that - if antimatter does, in fact, give off energy in any reasonable fashion - it would be such a particle/wave, and due to its very nature, humans would be unable to see it because the act of such vision would cause a matter/antimatter collision.

We haven't dealt with antimatter on a large enough scale to determine whether it has gravity or antigravity, but I would be willing to bet, at this point, that it probably has anti-gravitic properties (or at least appears to).

The point of this ridiculous diatribe in which I almost assuredly displayed an alarming misunderstanding of physics? I think that it would be reasonable to say that this dark matter/energy stuff physics is talking about nowadays is, in fact, all the antimatter that mysteriously went missing.

Yep. Seems pretty sensible to me.
