    Negative mass

    I see negative mass invoked for wormholes and warp drives, but does such a substance actually exist? What sort of properties would large quantities of it exhibit? Would a ball of it fall up?

    Negative mass is hypothetical. It does not exist, as far as we know. But I think physics does not rule it out.

    As to how it would behave, that's tricky.

    What definition of negative mass did you have in mind?
    The moment an instant lasted forever, we were destined for the leading edge of eternity.
