Only if their properties completely cancel and only (from our perspective) for incredibly brief times.

 

But given the right conditions the anti matter/matter particles don't annihilate each other and even when they do they leave produce additional electrons and positrons.

I'm sure Sutty gets this - as do I. But if everything has momentum, as blew apart from a central point - how is any of that momentum bringing things crashing together?

 

It may be hard to get your head around but the universe did not expand from a single point so there is no centre of the universe either.

Matter hasn't been created though. Because an equivalent anti particle has also been created, the balance is maintained. May the fourth be with you.

It's not a matter of anti-matter. Although the situation has some similarities. Anti-matter has positive mass like regular matter.

All properties of the pair of particles must cancel including their total mass/energy.

 

These are called virtual particles and only in the most unusual conditions (where extra energy is added) could one survive.

 

Energy is an absolutely conserved quantity within all interactions. Your model of new matter creation, even if an equal amount of anti-matter were also created) would mean the addition of energy to the universe. No experiment or observation in the whole field of physics suggests that this is a remote possibility.

All these questions make for some excellent sci-fi btw.

I read one recently that went from present day into the far future, Greg Bear maybe, I'm not sure. Anyway, the premise was that everything that exists now is just the result of a temporary stable state of the vacuum energy, and that ultimately it's doomed to heat death. So, through sci-fi means a message was sent back from the distant future (we're talking after proton decay of all matter distant) and the vacuum state collapsed into a lower, more stable, different state.

Deep time stories are great. I had to look up the time scale for proton decay. It puts the entire lifetime of the universe so far onto a scale where that's like the 1st second of your life when you're a century old!

The dont annihilate each other because most of the anti matter is missing and to date we dont know why.

No, that's not an explanation for matter popping into existence right now. That's just a puzzle we haven't yet been able to figure out.

 

Isn't ZPE based on the idea of particles popping into existence like this, out of the vacuum energy, but it happening such that one is inside the event horizon of a singularity and the other half outside, thus stopping their recombination and disappearance. Providing us with free energy from our point of view (but still satisfying the balance as far as the universe is concerned).

The Matter still exists though even though the anti matter cancels it out.

I think that's right. It's basically a matter of catching Hawking radiation, but Hawking radiation has yet to be detected and the process removes mass from the black hole which captures the particle and thus balances the energy.

So it's more like using a blackhole as a battery :-)

Seems like I might have got that wrong though, unbeliever said it's not as simple as matter/anti-matter.
