consider a break in pool, all the balls on the table go in all directions.
after the break take away pairs of spots and stripes (yellows and reds if you're british) that touched.
You'll undoubtably be left with some matter and some anti matter left.
What rules is anti-matter governed by?
If anti-matter were governed by our current laws (as they apply to the visible universe), then
it should also occur in the basic structure of what we see (member of galaxy, solar systems, rings, stars, etc.) drawn together by gravity. However, if that were the case, then we would see many more, or at least some, violent explosions at seemingly inexplicable times.
That, to me at least, would have to mean that anti-matter, while sharing source of existence with matter, also plays by a different set of laws.... anti-laws? Perhaps things like gravity still apply, but matter is not subject to it, just as it is not subject to matter's.
By the belief that matter and anti-matter share some interactive properties, what else, if anything would?
Is it possible that there is such a thing as an anti-galaxy as well?
only the matter and anti matter that collided would be wiped out.
Sure, that makes sense. My original stance was from my interpretation of how they presented the idea, they seemed to speak of the struggle between matter and anti-matter as a 'there can be only one', and matter happened to win. Hence my comment.
it's not that this no longer happens, it's that with less energy concerntration this is harder, - i.e in the first few seconds of the universe all matter and all energy inside the universe is concerntraited into a small space, as the energy spreads out it's concerntration is less.
Even in an environment of reasonable concentration, we are still able to observe matter simply vanishing. It returns... then repeats. This happens (from what I've studied) somewhat regularly, all around us.
My original contest was with the idea this happened because of the environment. The way it came across implied that only those conditions would cause matter to behave this way.
but the same as we can see rocks floating in space why can't ice float in space
You can see it in action if you live to see July 28th, 2061. Halley's comet will pass again and leave behind it a massive tail of melting ice/gas.
that is not combustion, that is nuclear fusion.
Knew that... but don't quote me.
Was just using an easy to understand example of existence of different forces/forms of a concept
