    Does anyone think it is possible that there is a parallel universe made of anti matter similar to this one? And if so, do you think the beings in that universe would find small amounts of matter in the same way we found small amounts of anti matter

    Think to yourself and keep that idea to yourself, someone will steal it. Trust me.

    And yes I do :wink:, but no-one here has probaby thought of that.

    Early on in the exploration of space, ie, early-mid 20c, a number of astrophysicists speculated that, even within our universe, different galaxies could be composed of anti-matter and matter, thereby balancing the total amount in the universe. Subsequent spectrographic analysis, I presume, has shown this not to be the case, but the theory, and speculation regarding it, has a good pedigree...

    Whether it is proved or not, i think there must be equal amounts of matter and anti-matter in our universe. Big-Bang should be justifying that if i am not mistaken.

    I think anyone who has learned a little bit about antimatter has thought of this. here's the problem. If there was a galaxy that was made entirely of antimatter, wouldn't it be utterly destroyed when it reached a galaxy made entirely of regular matter? If we looked into space, wouldn't we see this most violent reaction fairly easily? I had a idea a while ago on how there came to be an imballance, (as most people usualy do) but it was wild, and I discredited it myself. It's one of physic's great mysterys today I think (along with the gravitron, black holes, the coexistence of QM and GR, dark matter, and dark energy... I probably left some out...

    I dont think so as antimatter has a tendency to merge back with matter to form energy, thus destroying both antimatter and matter based galaxies. Antimatter is a byproduct of converting energy into matter, unless the antimatter is contained by magnetic fields it will recombine with the matter and turn back into energy.

    I was just about to reply to the initial thread in the same vein.

    It really annoys me when 'us' humans think when we have found something, we have found the ultimate truth. It's a mistake to be so presumptious.

    Of course there is just the same anti-matter as there is matter. It's logical and to refute otherwise discredits much of the fundamental laws which underpin our very existence.

    According to theory the energy at the big bang should have created equal amounts of matter and anti-matter. So if an anti-matter and matter galaxy collided, what form do you think the liberated energy would take? Photons. We should have been able to see brilliant displays of light in some areas of the the universe if this was the case.

    The best that cosmologists have come up with, as far as I know:

    1. There could have been slight imbalances in what was created at the beginning, and what we see of the universe is actually a small leftover surplus of normal matter with the vast majority having mutually annihilated along with the nearly as large amount of anti-matter that was initially formed.

    2. The weak nuclear force (correct me if I'm over-reaching folks) is now known to be the one non-symmetrical reaction in physics and may be implicated in (or at least give us a hint as to) the preponderance of matter in the universe.

    I dont quite know where this discussion is headed, but I wish to reply to the very first post.
    As per the new M (membrane) theory ( dont know if you've heard about it), Universes are assumed to be enclosed in vibrating membranes, and they collide with each other once in a while (million times the age of our universe!) and create disturbances. This is proposed to be the cause of the Big Bang.
    My,..well..thought is..that if a parallel univ was made mostly of antimatter, and if it , by chance, it collided with ours, all hell will break loose and the energy created will be enough to annihilate even other universes.
    It all seems so wild doesn't it?

    According to your theory universe creation would then be stuck in an infinite loop. Then we are down to a chicken and egg debate. It would be a paradox, I don't like paradoxic theories all that much.

    All interesting replies, the theory about colliding universes though intrigues me. I'll have to look up on it.

    Well actually this "colliding universe theory" isnt mine. Its something I heard about on TV. Its said to be a hypothetical concept, a result of string theory.

    Wouldent parallel be exactly the same and perpindicular be completly oppisite?

    Why does where the universe lie even make a difference? And how can their be more than one universe if existance itself is the universe?

    Anti-existance? lol How would we know?
