    If a star made up of exotic matter produces negative energy,then it would continue to absorb radiations from near by objects and will become hotter and hotter. Such a star would turn into a white hole eventually.
    However If photons of negative energy travels from a cold body to a hot body, we can imagine gravitons doing the same. If Gravity is reversed then objects will accelerate away from each other stretching the space around along with them. Also these negative massed objects could never form massive bodies like stars due to their mutual gravitational repulsion.
    This means that their "antigravity" should be weak locally but over huge distances, due to the shear number of particles involved it does make an impact.

    I know that Universe is undergoing accelerated expansion, but is the rate of acceleration a constant?
    If there was equal amount of matter of negative and positive mass at the time of big bang there would have been 3 types of collisions- matter antimatter collisions, matter-negative massed matter? collisions and antimatter-negative mass collisions.
    Since this was such a random event negative matter might have consumed more of antimatter than matter, giving rise to a Universe with surplus matter. This maybe the reason why "a small amount of matter" was left behind after all the matter anti matter collisions.

    we could run simulations of Big Bang bringing in negative mass into the scene. Have anyone tested this, what did they find out?

    I can see the logic of what you're getting at but I cannot accept negative energy as anything physically existing. If people had had that stance in 1800, phlogiston would still be accepted today since this hypothetical substance possessed negative mass i.e. when it was released from objects by combustion, the end products were HEAVIER than the ingredients.

    We now know that this was due to oxygen combining with the material combusted - but if negative mass were clung to, so would be the notion of phlogiston - and the theory of 'dephlogisticated air' (i.e. air with the oxygen removed, its place taken by CO2). As it is of course we have CO2 problems of a different kind today!

    So I cannot countenance dark energy stars since they would be reversing the 2nd law of thermodynamics too.
