Unfortunately it ends just where I'd like him to begin

I dont think I have read anything in what I'm about to say so I would appreciate it if anyone can tell me if they have.

The state of perfect entropy is that which is found in a singularity or a Boes-Einstien condensate where things are just too cold for any reactions to take place in matter and matter itself loses individual atomic identity. All atomic identity relies on heat to exist. Could it be that the expansion we see in the universe is driven by heat? The 3 degrees kelvin of heat left over from the big bang is actually the driving force of expansion and that when it cools to the billionths of a degree of a singularity expansion, or at least its acceleration, will cease?

Sort of following on from that in a loose sense it may be that Black Holes are in fact Entropy Machines. That they have a 'purpose' of removing heat from the universe. Black Holes appear to go through feeding phases. But they are 'messy eaters' and some of the material they accreted from close to the galactic core is ejected from the galaxy in huge jets. Such jets, as you can see in the image attached, throw large quantities of matter into the interstellar void where it is effectively removed from the star making/heat production cycle. The velocity of ejection is sufficient that much of what a black hole consumes is pushed beyond gravitational re-capture. Estimates claim that 5% of all accreted mass is thus ejected forever from the host galaxy. Keep repeating this process and you get a significant loss.

Again not read anything directly related to such an idea, just mere musing on ideas. If anybody has I would be most interested to read.

I thought black holes ejected x-rays...is the matter converted to x-rays? or is matter actually ejected?

And if matter or x-rays is ejected how does this tie to the connection to other universes theories?

No not just X-Rays are ejected. X-rays emissions are just the best way we have of detecting them. Even whole stars can be ejected in this way.
We have performed N-body simulations of the formation of hyper-velocity stars (HVS) in the centre of the Milky Way due to inspiralling intermediate-mass black holes (IMBHs). We find that due to dynamical friction, IMBHs sink into the centre of the Galaxy where they deplete the central cusp of stars. Some of these stars become HVS and are ejected with velocities sufficiently high to escape the Galaxy.

I am not sure but it could be that the supercooled state is some kind goal? In such a state everything becomes one, its a state of rest in which all information is contained. It could be that the universe is an experiment in trying to achieve perfect entropy or an very large experiment in trying to achieve 0.00000000000000000 Kelvin

WoW!! Seems even black holes can be ejected from galaxies.

We study the number and interaction rates of supermassive black holes in galactic bulges as predicted by hierarchical models of galaxy formation in which the spheroidal components of galaxies are formed by mergers. In bright ellipticals, the number of events that can eject a central supermassive binary black hole is large. Central binaries must therefore merge in less than a Hubble time – otherwise there will be too much scatter in the M–σ* relation and too many off-centre galactic nuclei. We propose that binary black holes are able to merge during the major gas accretion events that trigger QSO activity in galaxies. If this is the case, less than 10 per cent of faint ellipticals and 40 per cent of bright ellipticals are predicted to harbour binary black holes with near equal masses at their centres. This binary may be ejected away from the centre of the galaxy or even into intergalactic space in up to 20 per cent of the most luminous ellipticals. The number of low-mass black holes that can interact with the central object is predicted to be a strong function of galaxy luminosity. In most faint ellipticals, no black holes fall into the centre of the galaxy after the last major gas accretion event, but in the most luminous ellipticals, an average of 10 low-mass black holes interact with the central supermassive object after this time. It is expected that stars will be ejected from galaxy cores as these low mass ratio binaries harden. Multiple black holes in galactic bulges thus provide a natural explanation for the strong systematic trends in the observed central density profiles of ellipticals as a function of luminosity.

So our galaxy could be headed for a wandering supermassive black hole and we would never know it.

Now we see blackholes by not seeing what is beyond do we not...and light being warped?? So we'd know if we were heading toward one or one toward us, yes?

But in my mind I now have picture of a smbh sucking in another smbh and the former being ejected by the latter but as it travels in and then boomerangs out it gathers some material with it hence becoming the larger gravitionally smbh... It travels a distance away and then like on a giant rubber band the inititial hungry smbh gets caught up in the pull of the ejected and gets swallowed up only to get ejected and as well gather some back and this eternal infernal invisible perpetual motion yo-yo match ensues across the universe...each spewing off x-rays as they gobble galaxies and alternately each other...

(I just quit meandering through my office whilst pretending my fists are carnivorous smbh's and the folks around me are galaxies running scared...despite the fact that they avoided me...I percieved them as being swallowed up as x-rays spewed out between my curled little finger and/or thumb....they started talking...so I just sat in the conference room and turned my smbh fists into my little floating Bhudda....life is good)

No. Well not until it was sucking us in anyway. The SMBH in our galaxy only has a radius 8x that of our sun, but a mass about a billion times as great. If something that size approached us it would remain point sized till well within our solar system,by which time we would certainly be noticing the disappearance of the outer planets. In addition to that black holes cause a powerful gravitational lensing effect so that you would not see a black space/void but the light of the stars behind it bent round it by its gravity field.

Lmao, just tell em its a new 'assertive yoga' technique
