In time, the universe entire will eventually experience a state of 'heat death' where no chemical reactions can occur. An act of destruction so complete that even the act itself will not be remembered, to quote the late Heinz Pagels.
Seeing as all of this is many billions of years from now, I'm not worrying about it much. $;-)
I don’t agree that the universe will die a cold death.
If Einstein’s picture of Space-Time is correct, that it is like a rubber sheet with mass depressing it [gravity wells] in all it’s different forms and locations, then even if there were only two black holes left and they were trillions of light years apart, they would eventually collide............
Read it many times.......................
Thanks!
Asimov’s story is very interesting—no doubt.
But—it is based on extrapolation of our present knowledge—which will probably be laughably obsolete in a few hundred years.
One way to think about this is to take a look at the 1494 Treaty of Tordesillas—where the Kings of Spain and Portugal met with the Pope and divided the world in halves for their two empires.
They could never have imagined the world of today.
So it will be for current hairless apes—the universe is _not_ going to play by our “laws” or “rules”.
Celestial FiReworks or What?!?
Wow!!

I captured this galaxy last week. It's called M51 Whirlpool Galaxy. It's one of my favorites to visit.
M51 Galaxy and its companion, NGC 5195, is located about 30 million light years away. M51 estimated diameter is 76,000 light-years. It is believed a large black hole resides at the galaxy core or center.
225x30' ISO 2500 - Total iteration time 1h52m30s.
Whirlpool Galaxy with it’s Maytag-along Galaxy...........
Larry Niven did a whole series of SF stories about this phenomenon. TO the point, a race of aliens called Puppeteers were running the galaxy for eons — sort of like how the Dutch ran circles around everybody in Europe when their trading empire was at its peak. Then, the Puppeteers hired some guy to go take a peak at the center of the galaxy in an experimental ship they developed. He came back with a report that, yes, the center was a black hole. Worse, it had consumed a bunch of stars, causing them to explode. The products of this was a wave of high-energy, fatal, sanitizing particles coming thisaway. That wave would arrive in 20k years. Oops. Puppeteers were notorious cowards. So, they dropped everything and scrammed for the next galaxy over. This collapsed the entire galactic economy for years.
There were about a dozen follow-on novels about this. Fascinating read if you are willing to suspend disbelief on a few things.
It’s interesting as NGC 5195 appears as part of the M51 system but it’s not. NGC 5195 is actually separate and moving in behind M51.
And then it won’t be seen anymore, like the Kenmore Galaxy.................
I pity any life forms that may have developed that close to all the chaos and gravity well ( if such a thing were possible and observable), but I’m sure their end was quick, although we observing it from farther away would see it as an agonizing slow death.
Filaments, Schmilaments! What I see is a giant, heart-stopping demon with its shoulders and neck, particularly its spine, in red. Its purple left horn is broken off and the eye at the base of its skull under its good horn is fixed squarely on us! Ha, ha... I cannot look at random patterns and not see stuff... It's the me, before my mathematical and scientific training came along and tried to fix my brain. And it refuses to die, lol.
Very nice find. Fascinating. Thx.
Too much radiation for anything to develop...................
I see COOKIE MONSTER!.....................
Speaking of which, Andromeda seems to be getting awfully familiar. We weren’t even properly introduced IMHO.
Galaxies can merge and form bigger galaxies....................
Yeah but with casualties. Gravity is gravity, and Newton Third Law is still useful, if not precise.
Are there any intergalactic orphan stars out there?...................
