Three. The christian god is a holy trinity. But now I actually undertand where that comes from
Well if God is a triad of black holes merging, that is quite a convincing argument that God does not exist (as a triad. Many gods as pairs of merging BHs might, but not the Christian triad version)
Here is a paper estimating how often a PAIR of black holes merge:
https://dcc.ligo.org/LIGO-P1500217/public/main. Their conclusion in Fig 5 is:
Between more than one per year and a couple hundred per year in a giga parse cubic volume. (A parse is about 31 trilion Km and giga is E12, I think) I. e. It is a very big volume that would have one per year pair of Black Holes merging and their collision, even including the "ring down time," is less than a second.
The probably of three black holes merging (instead of two merging followed by a third merging with their union less than a second later) is vanishingly small, even for the entire universe. So god, as the simultaneous merger of three black holes does not exist. QED.
The Jews, were correct: If god exist as black hole merger, he/she is a unity, not a triad.
PS Will some mod please close this thread - there are at least two others, with serious content.
