Title says it all. Maybe it belongs more in Astrophysics but given the title...

If this is for real I'm surprised it's gotten so little attention..?

For our readers' convenience:

The LIGO/Virgo collaboration has recently announced the detection of a heavy binary black hole merger, with component masses that cannot be explained by standard stellar structure theory. In this letter we propose several explanations based on models of new physics, including new light particle losses, modified gravity, large extra dimensions, and a small magnetic moment of the neutrino. Each of these affect the physics of the pair-instability differently, leading to novel mechanisms for forming black holes inside the black hole mass gap.

By whom? Ill-informed bloggers? Over-hyping university press departments?

The whole shebang really. After all, everyone sems to be hungry for any thing that hints at new physics of any kind.

But if you tell my it's basically bunk I'm inclined to take your word for it, though I'd appreciate pointer to flaw in the paper of course. Especially flaws I would have a chance to understand. :)

I know the "QCD frontier" isn't exactly breaking news. Still. It's sort of new to me at least.
