Things I said 'No, of course not!' when asked if true:
Can gravitational waves be discerned against background noise from black hole mergers billions of lightyears away?
Can a particle ring like Jupiter and Uranus have exist well outside the Roche lobe of dwarf planet Quaoar?
And now, are black holes the source of dark energy and gain mass mostly not from accretion but from expansion of the universe?

@Mark15
1: Yes, assuming a measurement is too difficult was a mistake.
2: Do we have enough evidence to be sure it's a particle ring? Tidal forces are pretty well understood.
3: What do you think of Ethan Siegel's take? "The authors are assuming the existence of a coupling that isn’t [necessarily] there and ascribing the perceived evolution of the black hole-to-stellar mass ratio to [it]"

@fuy Thanks, I'll give Siegel's article a read.
