Matter, anti-matter, and singularities

  1. Jul 28, 2009 #1
    Lets say anti-matter is less sparse than it currently is. What would happen if two singularities one of matter and one of anti-matter were to merge? Anything special, or the same thing that happens every time matter and anti-matter merge?

    Hi CannedParadox ! Welcome to PF! :smile:

    I suspect all the particles and anti-particles would have fallen into the singularity, and therefore ceased to exist, before the collision.

    But if they hadn't, and they collided inside the joint event horizon, then they'd presumably convert into energy, which would almost immediately fall into the singularity anyway. :wink:

    well i think that if 2 black holes 1 is of antimatter and 2 is of matter they both will fall into singularities of each other while doing so,the particles and antiparticles will annihlate and both black holes will be destroyed.

    i have a question:-we know that matter can be converted into energy and vice-versa,as proved bye=mc^2,but how is it possible?

    Vikrant, this thread is over 2 years old!

    Anyways, even assuming that 2 black holes could form, one made of antimatter and the other matter, a collision between the two would do nothing. All of the energy released and particles created would still be inside the event horizon and none of it would escape.

    Particle colliders do this all the time. Particles are accelerated, crashed into each other, and the resulting sea of newly created particles have a combined rest mass greater than the rest mass of the colliding particles. The mass comes from the energy used to accelerate them. In fact, ANY generation or use of energy carries with it a transfer of mass. If you throw a frying pan onto your stovetop and heat it up the frying pan now has MORE mass than it did when it was cold. The increase is too little to notice in our every day lives however.
