Can't wait for LISA to get going. 10 Years!
I too have been following this BH3 business:
My understanding is most Supernovae leave a Black Hole after exploding. And there must have been a lot of them down history. IDK whether they attract dark matter to complicate things. You would think they do.
I am currently experimenting with astrophotography, despite some murky skies lately and a cold NE wind at night. Hoping to see this Corona Borealis Nova. I bought a Nikon D60 DSLR with an 18-55mm f3.5-f5.6 lens.
Camera shake is proving problematic but I am picking up faint stars, but it is possible to use a 30 second manual timer delay mode, a shortened tripod and a piece of Black Card as a very manual and clever shutter control to avoid trails.

These settings can be set in the menus, so I am optimistic.
I also want to get hold of my nephew's 35mm and 50mm f1.8 lenses which seem more suitable. F1.8 is four times the light of f3.5, which is a magnitude or more, magnitude being a x2.5 factor to be combined with longer shutter speed.
The Higgs Boson continues to baffle me, but am making some progress:

The key seems to be that the Higgs field, which is scalar and uniquely spin-0, breaks the expected symmetry as a Mexican Hat or Wine Bottle potential. Symmetries conserve properties like energy and momentum, but the Higgs Field bypasses some of the problems in the Goldstone theories.
Uniquely, Peter Higgs predicted the Boson which bears his name. Around a massive 125 GeV along with the heavy W and Z bosons of the weak force and the Top Quark.
The 1964 Higgs paper was beyond me, though the equations in it are no worse than in General Relativity. and the 1966 one only available on subscription. Yukawa potentials and the Goldstone Theorem are of course, highly technical things.
Onwards and upwards!
