Utter nonsense. Lagrangian points are nothing more than positions in space where relatively stable can be achieved, and black holes cannot be "ripped open". > As soon as the Lagrange surfaces There is no such thing as a "Lagrange surface". > hit the black hole surface, A black hole has no surface that could be “hit” as in a collision. The Schwarzschild surface, which has been called “the surface of a black hole”, is merely an event horizon. The only thing that changes for something that crosses that boundary (from the outside) is that it cannot come back again because its escape velocity would have to exceed that of the speed of light (and it may also be ripped apart by shear forces there if the black hole is rather small).

The gamma-ray burst (GRB) that coincided with GW150914 was observed by researchers with the Fermi Gamma-ray Space Telescope instead. And it is not "massive" at all (only 50 keV), compared to previous GRBs. V. Connaughton et al. (2016–02–11). “Fermi GBM Observations of LIGO Gravitational Wave event GW150914”. arXiv. arXiv:1602.03920v3 [astro-ph.HE], Subsequent analysis by researchers with the INTEGRAL telescope indicate that GW150914 has nothing to do with that GRB.

Utter nonsense. PointedEars -- I heard that entropy isn't what it used to be. (from: WolframAlpha)
