from your article:
The hub of the stellar carousel is a place where space and time end, and into which stars can disappear forever.
To me, that statement is just conjecture. Time and space do not end imo, but under the intense force of gravity, my belief is that the matter and energy falling into the black hole create a situation akin to going back in time in the first 300k years after the Big Bang when the plasma cloud reigned supreme. To me, a black hole is going in reverse. It is creating dense spots in the universe similar to the time not far removed from the Big Bang. If indeed there ever was a Big Bang lol. One of these black holes will end up so dense that it may end up becoming another universe.

No you didn't.

No it can't. The upper limit would be the speed of light.
Moving on.

AGW is not political.

If it wasn't political, there'd be no need to keep changing its name now would there.

Oh, there was one exception perhaps. I forgot about her.
There was a young lady named Bright
Whose speed was far faster than light;
She set out one day
In a relative way
And returned on the previous night.

I'm pretty sure the grey aliens can travel faster than the speed of light and plenty of people claim to have seen them.

You know, these Ancient Alien shows on several channels now are VERY interesting.
I see a lot more compelling evidence that we have been visited by extra-terrestrials than RUSSIAN collusion!
When you look at how big "outer space" is now with the Hubble telescope at work, it is hard to imagine that we are the only ones out there. Or the most advanced.

check out those NASA vids on youtube where they blur things out because something flew past the space station.
I think they are military related, and not always ours.

My assumption was accelerating to the what is now the point of the known observable universe (13+ billion light-years). I fully understand Einstein's general theory of relativity.
Yes...moving right along.

I don't understand anything, but maybe that's just me.
Start a new Thread named the Theory of Everything.

Of course we do not know ultimate reality, but science has done a commendable job advancing what we do know.
You know like......
the last 400 or so years of understanding
communications,
and
antibiotics,
Do you have a substitution?
Ouija Board maybe?

Surprised Oumuamua and its curious and laws of physics defying solar system visit hasn't drawn any attention in this thread...
When the best minds in the world shrug and say "aliens?" to describe its behavior that's pretty interesting.

It is being checked out carefully

Maybe it's an alien spacecraft.
Scientists have been puzzling over Oumuamua ever since the mysterious space object was observed tumbling past the sun in late 2017. Given its high speed and its unusual trajectory, the reddish, stadium-sized whatever-it-is had clearly come from outside our solar system. But its flattened, elongated shape and the way it accelerated on its way through the solar system set it apart from conventional asteroids and comets.
Now a pair of Harvard researchers are raising the possibility that Oumuamua is an alien spacecraft. As they say in a paper to be published Nov. 12 in The Astrophysical Journal Letters, the object "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization."

The researchers aren't claiming outright that aliens sent Oumuamua. But after a careful mathematical analysis of the way the interstellar object sped up as it shot past the sun, they say Oumuamua could be a spacecraft pushed through space by light falling on its surface — or, as they put it in the paper, a "lightsail of artificial origin."

Imagine looking at that data and realizing it continued to accelerate after its slingshot?
"Ummm... wut...?"

Can't say I can explain it, but it is radial solar pressure and tghe speculation is it is very thin
Could Solar Radiation Pressure Explain 'Oumuamua's Peculiar Acceleration?
http://spaceref.com/interstellar/cou...eleration.html
For a thin sheet, this requires a width of w≈0.3−0.9 mm. We find that although extremely thin, such an object would survive an interstellar travel over Galactic distances of ∼5 kpc , withstanding collisions with gas and dust-grains as well as stresses from rotation and tidal forces. We discuss the possible origins of such an object including the possibility that it might be a lightsail of artificial origin. Our general results apply to any light probes designed for interstellar travel.
I wonder if that means it is tacking like an old clipper ship?
...."Tacking or coming about is a sailing maneuver by which a sailing vessel, whose desired course is into the wind, turns its bow toward the wind so that the direction from which the wind blows changes from one side to the other, allowing progress in the desired direction".?????
