Using just a few principles from both these disiplines indicate that holes don't just 'merge'. The gravity fields set up by colliding black holes would cancel each other along the intersection axis in the time interval prior to collision. This interval is longer than you'd expect as two black holes would most likely collide at oblique angles and go into a tight spiral orbit about each other before collision. Imagine what this means! Two little mass bottles under incredible pressure suddenly having their corks pulled out. Calculations are a little intense but the result can be summed up in a word... BBBBB OOOO OOOO MM MM !! B B O O O O M M M M !! BBBBB O O O O M MM M !! B B O O O O M M BBBBB OOOO OOOO M M !! Just a bit over 27% of the total mass of both holes would be converted into PURE ENERGY! Another 18% is released as actual mass and the remaining forms into a black hole with severe spin and g-field fluctuation. We're talking here about a bang that would make a supernova seem like a fart in an elevator. :-) The values above were calculated on a Cray by a group of English Profs. at Oxford (I believe) and may not be accurate as they were pulled from the dregs of my memory. If anybody's interested I can dig up exactly who and where this info came from and provide either referances or more info. Sorry I don't know if spin or charge would make a difference but I suspect they would be negligable considering the overwhelming g-force involved.
