I know it seems unlikely to accumulate sufficient amount of antimatter to let it collapse under its own weight to become a black hole(maybe the gravity works differently I don't know) since they will definitely react aggressively with ordinary matter which made up most of our known universe producing energy.
My question is can we accelerate antimatters and then let them collide with enough energy to produce a tiny black hole? would this tiny black hole shares similar properties with its normal counterparts?
Oops I almost forgot what kind of particles are produced in the abovementioned collision? (e.g. antiproton-antiproton)
