    If such a thing as an anti-gravity particle existed and was left to its own devices where would it go or end up in this universe?

    If such a thing as an anti-gravity particle existed, what properties do you envision that it would have? I ask because I do not understand what you mean by anti-gravity. Are you suggesting that it is impervious to gravity, which is not possible, IMO, or what?

    Do all you cosmologists like to complicate things? I didn't think this would be too difficult but what do I know? That's why its a dumb question I guess.

    How about it has the exact opposite affect on the matter we know of, repulsion versus attraction. Just a hypothetical question.

    When you say anti-gravity particle I am not clear whether you mean a particle like, say, a neutron, but having negative mass, or the particle by which the repulsive force of gravity is transmitted. i.e. a anti-graviton.

    Assuming you mean the former then it would end up in the largest open space it could find, if it was a neutron, or other electrically neutral particle.

    If it were a charged particle it would end up pretty much where any charged particle tends to end up - partnering a particle of opposite charge. The electromagnetic forces are many orders of magnitude greater than the gravitational, so a little repulsion from one particle wouldn't do much.

    if there is a particle wich gives a repulsive force on normal matter it will ave to have negative mass, but it would be attractive on its own type of matter

    Your original question was phrased in a way that meant there was only a single particle. Consequently the issue of its reaction with similar particles was not considered.

    Given your definition, I suspect that the particle would go where other particles go and end up where other particles end up. It would, of course, take a different route to get there.

    Where do you think that such a particle would end up?

    My own imaginary version of anti-gravity is a force that is much-much weaker than gravity itself, in fact weaker than all other forces, thus you will never notice its effects on earth itself, but acting on a much larger scale and distance than gravity can (ex: 2 light years?).

    Such imaginary gravity could probably not be measured on our scale but migh be observed on interstellar scale.

    I also imagine a ultra-gravity that is even weaker but acts on a galactic scale, as well as an utlra-anti-gravity that again is even weaker still but acts on a inter-galactic scale.

    By the same token of alternating forces (inverse to scale), I also imagine a much stronger repulsive force than the Strong force, but on a much smaller scale.

    (In my imaginary speculative universe, repulsive and attractive forces would cancel each other out but are distributed across different scales, making possible clusters of matter on different scales. But then poof, I wake up from the daydream and all that's my imagination)
