I was surprised to find this feather had blown in from the garden last night.
ChatGPT told me all about it. Who knows what it is?

I think we just have to stop testing for them.

"Black holes this massive are forbidden through standard stellar evolution models. One possibility is that the two black holes in this binary formed through earlier mergers of smaller black holes."
So this is more likely than them originating from black hole/normal star binary mergers?

This is from last month. We’ve now had to upgrade to three large, and two smaller trays for the wood pigeons and the starlings to enjoy.

“Our results can be explained well by assuming self-interacting dark matter”
Now I have to sit here and think about that.
It ‘attracts itself’, like normal matter does?
I don’t think it occurred to me that it might, or might not, do that.

Disappointing. It reminds of when it felt like missions to Mars were constantly failing.
Somehow, NASA made it look almost easy with the Surveyor program in the 1960’s. It can’t just be about throwing huge amounts of money at the problem.

With the stars at many distances it should look random, but it sort of looks ‘foamy’ to me. I expect it is an illusion but it would be fun to compare it with a simple simulation. (Would need to be make sure it was actually random.)

I wonder if there are similar towers below the rings, or if one side has more than the other.
(If the shepherd moons spend equal time above and below the ring-plain then I guess things should equal out.)
