Default If you want cold, check out a quiescent BH (Was... )

So let me get this right... BHs are far colder than the lowest

degrees of hot jets of particles ejected for billions of miles along its
rotational axis by matter about to be sucked into the BH.

The jets are still `outside` the event horizon, composed of material
from the accretion disc that's been "backfired" along the polar axis
by a little-understood magnetohydrodynamic (MHD) process.

Black Holes are known for their tremendous gravity. *That gravity interprets

So perhaps you could explain to us dummies where the negative (-) absolute
zero temperatures supposedly come from that you claim to exist in a BH.

Frames of referance again. It's certainly mucho hot inside the BH. But
from here 'outside', the black body temperature of a quiescent (non-
accreting) BH will be very close to absolute zero (discounting any
negligible "Hawking radiation").
