Well I read this article https://en.wikipedia.org/wiki/Abhas_Mitra

and he has claimed that "The so-called massive Black Hole Candidates (BHCs) must be quasi-black holes rather than exact black holes"

Yet people tell that the wave detected was due to the joining of 2 black holes.

So are there black holes or not?

Any comments?

What LIGO experiment observed are two very dense and heavy celestial object collide and thus giving ripples in space-time, known as gravitational waves. Abhas Mitra's claim doesn't get forfeited by it. Even if the objects were not black holes but rather Eternally Collapsing Objects(ECO's) as Dr. Mitra claims, they would still give you same wave structure detected. The difference between the two theories are completely about the internal structure of black holes and has nothing to do with their external behaviours i.e. creating gravity waves and so on.
