I've forgotten how to post images (I'm getting old )
I would say that it looks like it covers about 25% of the diameter of the Mimas
... as seen from Saturn.
Probably much smaller than the diameter of the impact crater of our dinosaur killing asteroid ...?
But how come the Search Information says Confirmed vs Provisional?
So WE still aren't Sure how many exact Moons they have?
Juno & Voyager did take a closer look, Right?
Thanx Hal for setting me straight...Again!
Roger Penrose imagined a Cyclical Universe, isn't it? So why'd he do dat?
Aside:Obviously the dinosaurs didn't have a space program, lol.176747,176829
Yep!& They did not have underground bunkers or long term food storage facilities, not sure if they were a global species, like spread out all over the planet like humans.
Returning back to the Original flavour of this OP...The Observable Edge of the Universe is drifting away FTL, Correct?
So if there ever was to be a new BB at the Farthest Edge of the Universe, how would/could We Observe it?
If WE cannot Observe/Measure it & there ain't no Data/Evidence for it, does it then mean it's Not Real?
P.S. - i wonder if the Universe is what We make off of it, based on Our species potential & capacity of Understanding.🧠(human brain emoji)

I'd say no, though you do need some evidence to support a theory.
Then what happens if there are really " Multiple Universes " but no way for Us to observe, measure or obtain any evidence for Them?...

But speculation can be fun, lol.Yes Indeed!Speculating is Amusing.Assuming higher dimensions exist, Guessing gravity penetrates thru all of em, using all sorts of calculations to derive an equation which could predict future results with a very high rate of accuracy is quite interesting.I mean, if it works, then why not!QuoteP.S. - i wonder if the Universe is what We make off of it, based on Our species potential & capacity of Understanding.🧠(human brain emoji)I guess it is what we make of it, but maybe if we were more brainy we could make more sense of it.Yep!Humans are considered to be at the pinnacle of intellectual intelligence, but that's in comparison to the other species around Us...I'm assuming We are Clever, but not the Cleverest.
The " New Theories " section limits Us to be inside the bounds Logical Reasoning & Critical Thinking...Maybe, U should create a New OP in the " Just Chat " section..& name it ' Wild Speculative Imagination '.P.S. - lol😇(angel smiles emoji)
current Standard Cosmology, which I understand depicts finite space to be expanding
My question is, does the BB model refer to the action going on at the expanding boundary of the universe as creating space and matter out of nothingness?
is it consistent to predict that anti-space or negative space, and anti-matter are building up and exist beyond that expanding universe, in a sort of anti or negative universe?
Most models presume space to be infinite.
If the space is infinite then how the space could expand to the infinity in only 13.8BY?
Quote from: Dave Lev on 07/03/2023 19:53:18If the space is infinite then how the space could expand to the infinity in only 13.8BY?The size of the observable universe is finite in part because light has only been able to travel for 13.8 billion years and in part because objects beyond a certain distance are recessing away from us too fast to ever be seen.
It's true that you can trace all the matter in our observable universe back to a tiny space, but that doesn't include all the matter that would be outside our observable universe.
Therefore, why do we insist on 13.8BY as some magic number?
Don't you agree that our mission is to explain the entire space/universe and not just the part/section that we observe/see which is called observable universe?
I would like to remind you that there was a time when people on earth thought that our planet is flat and if you cross the horizon, you might fall into the open space.Hence, what we see is not good enough - not for today and not for the past.
Hence, as the real space is infinite then why can't we assume that the real universe is also infinite.
Why do we refuse to accept the simple understanding that infinite space & Universe could exist if the time is also infinite or at least much bigger than this friction of moment (comparing to the infinity)
