Head-on Collision of Two Black Holes

Merging worldlines or "Pair of Pants"

This movie shows the evolution of the event horizon for a head-on collision of two black holes. The initial data set corresponds to the separation parameter mu=2.2, representing an initial separation between the holes of L=8.97M. The geometric embedding of the horizon, which indicates the true dynamics of the horizon amd removes spurious coordinate effects, is shown for the timescale of the coalescence and approximately a single period of oscillation. The rotation has been added to the film to enhance the visualization; the collision actually has no rotation.

This work was published in league with Grand Challenge (Binary Black Hole) Alliance as part of a major article appearing in Science, Vol. 270, November 10, 1995, p.941-947.
