I don't like it— two massive Black Holes each twirling at the core of two merging galaxies get close enough to fuse together then quick as a wink just as they are melting into a New Black Hole Blob they undergo something called a "spin-ﬂip"
they change the axes of their spins and the fused-together Black Hole Blob gets its own quick as a cricket's foot
Don't like it at all
And then the new Black Hole Blob sometimes bounces back and forth inside its mergèd Galaxy
till it settles at the center
but sometimes a "newly" up-sized Black Hole leaves its Galaxy to sail out munchingly on its own into the Universal It
I don't like it
Nothing about it in the Bhagavad Gita the Book of Revelation Shakespeare, Sappho, or Allen Ginsberg
