how about such way to to get out of black hole:
we have system of 2 equal size black holes orbiting each other in such distance that horizons overlap but not much. mass center of this system is in the center.
now relatively small and indestructible object is flying along rotation axis directly into mass center of this binary system.
that object will go below horizons of both black holes but since mass center is empty, it wont hit anything.
so it should get out from below horizon? or is there something that can keep it inside.
imagine that you fall into black hole but with very high speed to that you can stay below its horizon for long enough
and while you are falling into it another similar size black hole passes at very close distance, so that they cancel each others gravity but since singularity does not touch horizon they should not merge and can rotate about each other for quite long time.
so if gravity is canceled we can easily get out isn't it so?
flowing question is if we have 2 equal size black holes rotating about each other and they finally fall beyond each other horizons. so according usual theory they should merge into singularity but where their angular momentum will go? it does not seem possible that they can simply fall to the center of this system.
and if such system can at last temporary exist then again we can easily go through its horizon, because gravity center of that formation is empty, so we cant fall and hit singularity and so we should get out from inside of horizon.
is that possible or there is something that can not allow all that happen?
