Precisely! Since, J T-D C, you obviously know a bit about Quantum Mechanics, you are aware of Heisenberg's Uncertainty Principle, and also about Beckenstein-Hawking radiation at the event horizon of a black hole.

Now consider this possible scenario: A particle-antiparticle pair erupts into existence, in accordance with Heisenberg, very soon after the Big Bang. Inflationary theory suggests that those particles may be swept far away from each other during the period of cosmic inflation. When inflation stops, the two particles cannot annihilate one another because they are too far away from each other. You have a discontinuity in the universe - an imbalance that cannot correct itself. A positive charge on one side of the universe, a negative charge on the other.

Gravity coalesces matter around these discontinuities. It could have occurred many many times during the inflationary epoch. It could also explain the origin of the entirety of matter that we observe. Hey, I could be up for a Nobel Prize with this!

Not really, because then it's just shifting the burden of explanation onto Inflation, which is still not fully understood.

You're right - this is fun!

just curious, but wouldn't we then have the same number of anti-particles for each type of particle? do we?

JTDC, I think you may be ready for a lucrative career in this! But I seem to remember that you're female, nicht wahr? If so. the fundies won't suffer you to teach, but hey - you could be Dr Dino's cheerleader!

No wait - you'd make him look like the friggin' moron he is.....

Actually, I'm not female. I don't recall why that impression was ever given...I dunno.

This is great fun, but I too tired to come up with more "responses". On the other hand, this has given me a new idea!

I'll post a poll.

Yep. So far as we can tell with the information we have. Which is actually not enough to make a broad statement about the universe as a whole. The hypothesis that there are equal numbers of particles and antiparticles is consistent with current theory.

interesting! thanks! so now i'm curious as to where most of these antiparticles reside.

Don't you people get it? Evolution is utterly and finally impossible by any physical standards. There are a good many reasons to hold it utterly implausible--from biological to chemical to the very laws of physics. I'll start with a few:

Universal gravitation: Given that all matter tends to attract to itself, and will always attract to the center of mass, the Big Bang is impossible. Since such an "explosion" would result in an equal distribution of mass, all gravity would be towards the central point--not multiple, spread out points. This would result in a single clump of matter in the center--pretty boring. But even assuming that magically this matter manages to get out, the soalr system would be impossible. Since gravity draws to the center of mass, the formation of planets would be impossible--all mass would have ended up in the sun, leaving a very uniteresting situation. This means that God MUST have created the universe and the solar system.

The above would only apply to a finite and STATIC (not moving) universe, because you cannot have a finite and static universe where gravity is attractive. But since the universe is infinite yet has a boundary (if you have trouble with this concept read "A Brief History of Time"), and is constantly in motion, the above argument does not apply. Also, gravity is the weakest of the four forces, yet it works over the longest distances as compared to the others.

D'oh! My bad. I think I had you mentally entangled with christ-on-a-stick. She is a she. Maybe it's the whole tap-dancin, top hat, walking-stick connection, or else I'm just more senile today than yesterday............
