Great explanation as alwaysMartyMurray . But what's disturbing me about Question 3 is the use of "... the hot intergalactic gas is not cooling andsettling" in Para 2.
How is this phrase different from "the hot intergalactic gas is neither cooling norsettling" ?
Because as I understand it, the hot intergalactic gas is always moving towards the central black hole (i.e. settling). I feel like Para 2 suggests that whenever huge bubbles are present, the gas can't really cool down but is always settling (but since both cooling and settling are requisites for forming a star, stars are not formed in this case).
I say this because I don't see anywhere in the passage any implication that the movement of gas towards the central black hole ever stops (or move outwards for that matter). There are queues in the passage suggesting that the movement slows down, like, "...diminishing itsinflow" , "....the black hole spins moreslowly..." .
