I looked up your answer & went from there. |

They cannot rotate at EXACTLY the same speed ( down to the nth decimal ) so there must be a residual rotation, no? Good night! Benoît Morrissette |

Hi Rob I think two blackholes colliding might be rare,but do happen. We
dectect two neutron stars revolving around each other (binary system),and the measurements made how they are getting closer,and closer together(will collide someday) got the two astronomers doing the measurements for 10 years Nobels. BH have to be doing the same thing. I would think their force of gravity would be so great when their obits get close enough that they would not spin. They would rotate like a dumbell. Locked together with the same side of their event horizons, (like siamese twins) As they get very close there would be no tearing of each other apart. A trillionth of a second before touching they both would reach the speed of light. If both black holes have diameters of close to 8 million miles they would have their singularites explode in a trillionth of a second (the action to release their singularities to space a billion times faster than light.) I have stopped light an inch and a half after it left its source. To match the time of the action of two singularites touching I would have to take a picture of a photon as it leaves the electron,and the distance half the size of a billionth of a Planck length. The uncertainty Principle makes this impossable Bert |

Whats your thoughts on what would happen? NCSA used a Cray Supercomputer to figure out what would happen. Read the article he http://archive.ncsa.uiuc.edu/SCMS/Di...es-Seidel.html The evolution of the collision of two equal mass black holes was computed using a Cray C-90 supercomputer at the Pittsburgh Supercomputing Center and Cray Y-MP at NCSA. The black holes start initially at rest, and accelerate towards each other as a result of their mutual attraction due to gravity. As the holes collide, a large, distorted black hole is formed, which vibrates at its characteristic frequency. The final oscillating hole emits gravitational waves at this frequency as it settles down to its quiet, spherical state. -- ____________________________ Pear pimples for hairy fishnuts? |
