What would happen if two black holes collided?
1) “The ripples in space-time created when two black holes merge have been modelled to unprecedented accuracy, according to Einstein’s equations, by a powerful new computer simulation. The “waveform” signatures produced in the simulation should help researchers identify the ripples in the data from gravitational wave detectors. Powerful gravitational waves are thought to shake the fabric of space-time when two black holes spiral towards each other and eventually merge. The waves have not yet been observed, but researchers have been trying to simulate the process on computers in order to predict the expected signal. That will help the nascent searches now in progress. The signals, called “waveforms”, are shaped by factors such as the frequency at which the two black holes orbit each other, their relative masses and their spins. But modelling the merger has proven exceptionally difficult because the process is governed by Einstein’s theory of general relativity.” “The simulation followed
