The LIGO detector has now seen at least two black hole mergers. The second merger it spotted was about what we would expect given a binary system of two massive stars. Both explode, leaving black holes behind that are just a bit more massive than the Sun; these later go on to merge.

But the first merger detected by LIGO was something rather unusual given that both black holes were around 30 times the Sun's mass. So far, we have not observed anything that could produce black holes in that mass range. Now, a new modeling study suggests that mergers with these sorts of masses might be common—but only if stars can collapse directly into a black hole without exploding first. This situation would require some of the Universe's most luminous stars to simply be winking out of existence.

Hallo poppageek!
Seems to be interesting.I´ll read this in detail soon.

Kind regards and happy crunching
