in the first and this report FFU report warns: just because you don't see light doesn't mean it isn't hot as a (neutron star) - infact the changeover between when visible light stops getting emitted is ... less than spectacular, indicating no heat was lost

on the History channel evidence is that "galaxy" like our own (the Milky Way Galaxy) "dies" (stops producing stars) when it's average temperature rises - but what isn't "known for sure" is when the black hole at the center causes it (if rises in Tb are purely due to specific events - or are continual)

Black Hole spin blindingly fast - fast enough to cause light to "bend" (or simply, be out of the visible spectrum). But as we know - radiation, if you detect it or not, if its there, causes heating that eventually a simple thermometer can read. is black hole heating impossible does heat not escape? what about star heating? how quick does a galaxy without a black hole loose it's heating (if it has composition similar to milkyway)? tune in much later because for now these kinds of questions are hard and can't be answered

the article above louds a LAB EXPERIMENT done with $gov money claiming to have created a black hole in a lab to confirm existing theories of "escaping particles" (quite a messy thing to measure in a lab - how would one judge error of method used?)

WHAT IS KNOWN is that during black hole flares galaxies warm significantly (but how a galaxy looses and retains heat is not so clear) (which last ) (or major ejections - called quasar ejection sometimes), significant galaxy heating occurs. (i'm having problems finding how long these massive star eating jets occur eruptions occur 200,000 light-years long, then certainly at least 200,000 years it took to get that way - and something longer we guess)

Our milky way black hole COULD erupt at any moment (or any million year) - all that is known is it hasn't in a very long time and the eruptions are thought to be eventual. If it did - life on our planet might very well change.

the funny thing is if these black hole "relativistic jets" (used to be called quasars) spit out axial energy

What doesn't things perpendicular to the event (the milky way disk) get cooler instead of warmer? shouldn't loosing energy and mass (spit out 200 million light years in the opposite direction) DRAIN gravity and heat from the milky way or end up equal? but it DOESN'T - what is known is that significant heating occurs during the event - not so well understood is how a galaxy could RETAIN heat (perhaps stars are excited or gravity is loosened or tightened) (remember hot galaxy do not produce stars) and what the temperature gain loss factors all are.

theorized is a black hole might have a jet due to consuming a neutron star or another black hole. a zero sum game though at a distance.

PERHAPS the wrappings, the "vibes" of the black hole extend in ways we cannot see or detect yet

also seen and discussed is the (gas ring) around the black hole, during ejection, gets a corona. obviously temperature rises.

one could say if the black hole (spin) reduces (due to collision with) and is given off as heat (a zero sum) that explains everything ... except what kind of radiation a black hole has outside of the quasar event - if there is galaxy heating yet unknown due to it

As the resident science guy here on FFXU, here is the only type of black hole we are interested in
