“Next, Alice measures the total angular momentum, or spin, of the black holeâ€â€both its magnitude and, roughly speaking, how much it lines up with a particular axis. With those two bits of information in hand, she then tosses in her electron, losing it forever.”
Ummmm.....doesn’t her measurement also force the collapse of the black hole’s cumulative wave function? :)
I would think that might be an issue...
Then again, I’m the type of guy that figures the Big Bang and black hole theories can’t possibly both be true, because they are contradictory in their predictions of what happens when you gather enough mass to form a singularity. One says nothing can ever escape, and the other says you get a big explosion!
