In this story, I’m reading along looking for the on/off switch the headline talks about.
I’ve always wondered what causes black holes to “mysteriously” stop feeding, so I was reading with some interest.
Now, is it just me, or is the story simply saying:
Black holes stop sucking matter in when there’s no matter within it’s gravitational field to grab.
Ummm… ok, now this seemed like something incredibly obvious to me from the very first PBS special on black holes I saw years and years ago.
So what’s the big “story” in this???
I mean, the way I’m reading it, the thing’s always on, it’s just out of matter to grab. Send more matter it’s direction and it will get sucked in. No matter, no radiation from matter getting sucked in.
So what am I missing?
