Dear Friends!
Q.There was no direct evidence of binary black holes till September 14,2015,when signals coming from about 1.3 billion light years away were captured by LIGO.
Now my question is that how in advance we knew about the specific colliding pair.Did we theoretically predict the graph (between what values?)and did the real graph matched to a high degree with predicted graph.
