Many big bang theories says that there were created equally or almost equally amounts of matter and antimatter at the beginning of time. But the problem of this is that why hasn't all the matter and antimatter annihilated? Scientists have come up with some possible explanations, but what about this one:<br /><br />I've heard that some physists believe that antimatter is the same as matter travelling backwards in time. So what if at the big bang there WAS created equal amounts of matter and antimatter. But the reason why it was not all annihilated was that the matter and antimatter travelled trough time in different directions, and was therefore separated the same instant they were created? So we have another universe that's like ours and also started at the same big bang as ours, except this universe is travelling the other way on the time scale, or something? And this is why we have only matter in our universe, while all the antimatter is in the other universe travelling in the opposite direction of time relative to us.<br /><br />Is this possible with what we today know about physics? I'm no astrophysist, so I don't know if there is something fundamentally wrong with this, or if I've totally misunderstood the nature of backwards-in-time-travelling-antimatter or whatever. This just popped into my head while I was reading an article about antimatter. Is it all just gibberish or might it be something in it? If there actually is something in this, I guess someone else would have thought about it, but I couldn't find anything about it on the web (but then again I didn't search for more than like 30 seconds <img src="/images/icons/smile.gif" />). So... yeah?
