Reply: I guess "universe" pretty much says it all.

I'm looking at an old copy of Astronomy magazine and the lead story is "Our trillion-galaxy universe".

My response would be that they have grossly underestimated the universe, assuming that I am right when I proclaim that the universe is infinite and filled with an infinite number of star filled galaxies.

174669,


My aggressive estimation says a trillion  doesn't even come close based on my premise that when it comes to "infinite", any finite number is almost nothing, almost nowhere, almost never. So upping the "guess" from 100 billion to a trillion back in 2017 was a big leap, but I wonder what they are saying today?

Can the Above Image, thru Wild Speculative Imagination, depict a Cyclical or Splitting Universe/s?

Can the Above Image, thru Wild Speculative Imagination, depict a Cyclical or Splitting Universe/s?

I don't think so. If the universe is infinite (a logical thought ), the impossible task of splitting a spacial infinity would give you two spacial infinites, and logically there can only be one. Once you establish a boundary between two adjacent spaces, that precludes two infinite spaces.

[Bogie_smiles (OP)]

If, in fact, the universe is infinite and eternal, a status which I have argued in favor of since my early days on the Internet, then the observable universe is quite insignificant in comparison. But that insignificant patch of space has life in it, and if it is typical of all of the rest of the universe, then life would be scattered throughout the entire "place". In that scenario, I think we could call the universe an infinite system that hosts life throughout, and there is no reason to believe that life has not always existed.

As for the level of intelligence of any/various advanced life forms that may have risen across space and time, it isn't too far fetched to equate the intelligence of those life forms to ours here on Earth. If we consider that level of intelligence to be some kind of a norm among other advanced life forms that may have existed or currently exist across the universe, the next question that comes to my mind is the technological capability of their civilizations.

YeP!

The Image represents the Logical Map.
I had brought it up previously in another OP.
& Perhaps it was Hal, who put me in place sayin it's Not what I'm wildly speculating it to be.

I had watched a Utube video of ' Veritasium ' who explained it.
I picked up on the Image from there.

He perhaps connected it to ' Water dripping out randomly from a Faucet ' & kinda explained ' Population growth/decline rates of Rabbits ' .

He even " Flipped " the Image n said it's a sorta Mandelbrot Diagram.
Anyways, the sheer Enthusiasm with which he explained stuff got me thinking the Image has a much deeper meaning.

P.S. - It's Hard to get Rid of certain Things that keep coming back to Haunt You...but not impossible.

[Bogie_smiles (OP)]

Yes, you've repeated that a great many times, but you edited out the important part of my post: "Have you given thought as to resolving the problems instead of ignoring them?"

I considered that a rhetorical question. I don't have the knowledge or background to qualify me to solve the kinds of problems that the scientific community is dealing with. I generally hypothesize and speculate about an infinite and eternal universe, i.e., a cosmological model of a universe that has always existed and is generally the same on a large scale, wherever you are in it. I'm sure I would be mostly wrong when it comes to problem solving.

Moving on to the Herschel crater in Mimas, a moon of Jupiter ... This is an impressive asteroid crater, and according to a description in "Universe, A Journey from Earth to the Edge of the Cosmos", based on the stress marks on the opposite hemisphere, "the Herschel crater" covers nearly a quarter of Mimas' surface, and is 10 kilometers deep; the impact came close to destroying the moon. I wonder if that kind of impact, from a different angle, could throw the small moon out of orbit and into a collision path with Earth?

Thanx Hal for setting me straight...Again!
(ha ha)

One thing leads to the next, n then another n another...
Just found out Jupiter has 80 & Saturn 83 Moons..
WooW!
I didn't know that.

But how come the Search Information says Confirmed vs Provisional?
Wut d HecK?
So WE still aren't Sure how many exact Moons they have?
How's that even possible?
Juno & Voyager did take a closer look, Right?

P.S. - Roger Penrose imagined a Cyclical Universe, isn't it?
So why'd he do dat?

[Bogie_smiles (OP)]

5% at best, about a 20th. Still dang impressive.

Mimas orbits Saturn, not Jupiter.

I stand corrected.

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 ...?

It looks like the death star:

"That's no moon. Oh wait, it's a moon"

I would say that it looks like it covers about 25% of the diameter of the Mimas

Close enough. I get 30% of the diameter, or about 10% of the circumference, which makes it cover maybe 3% of the surface, a slight reduction of my prior estimate.

... as seen from Saturn.

Although most images including the one I posted are not from Saturn. Most are as seen from Earth, as evidenced by the fact that we see most of the daylight side.

Probably much smaller than the diameter of the impact crater of our dinosaur killing asteroid ...?

The Mimas crater is about 130 km across, whereas the Chicxulub crater (Yucatan) is about 150 km across, larger, but not much larger. It's the second largest crater on Earth, with Vredefort being a bit bigger, in South Africa.

There's no trace of the Theia impact structure since that was a melt-the-whole-thing-and-start-over sort of deal. It would not be meaningful to say 'here's the spot where it hit'.

But how come the Search Information says Confirmed vs Provisional?

The provisional ones have not had their sightings or orbits yet confirmed. They might just be a passing object and not in orbit at all.

So WE still aren't Sure how many exact Moons they have?

No, they're really far away and it's awful dark out there, and some of these things are pretty tiny. There must be a threshold of what constitutes a moon vs just a small pebble that happens to be in orbit about something.

Juno & Voyager did take a closer look, Right?

Yes, and they found/confirmed a bunch, but the didn't linger long enough to do a thorough scan of the area. Juno didn't make it to Saturn either.

Thanx Hal for setting me straight...Again!

OK, so setting you even more straight, I'm Halc (rhymes with 'false'). There is another user (occasional poster) on this site whose ID is Hal. I'm not him.

Roger Penrose imagined a Cyclical Universe, isn't it?  So why'd he do dat?

Try something different? Hard to say what he suggests, but it seems like it is playing with conformal time. The view requires infinite time to pass as measured by one bang before the next one happens, and it is unclear if it allows the bang to have any energy associated with it. The bangs still happen everywhere, which is the same as nowhere given infinite time and spacetime becomes singular in a way.

To Post an Image...

I first search for it Online.
(make sure it's a free pass n has no copyrights on it)

Then i download the Image.
(sometimes if the download site seems eerily funny, i click a screenshot)

Then right below this typing box i go to " Attachments and other options "
(Click the ➕ box mark & it opens n expands)

Then click " Choose File " option & choose the latest downloaded image or screenshot from my system.

Then setting back the Cursor into the typing box, wherever i would like the Image to be placed...
Then just click "(Insert Attachment 0)"
& Finally Post.

P.S. - Thnx 4 d info Halc.
As straight as SLAC!

It looks like the DART mission was successful. We now can be more confident that we can alter the path of an asteroid that is on a collision course with Earth; that is good to know! However, I think there is talk of using atomic weapons if needed to alter the course of bigger astroids. That method seems to have a whole different set of possible repercussions.




Aside:
Obviously the dinosaurs didn't have a space program, lol.

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.

I remember driving out into the high dessert from Las Vegas back in the 70's and coming to petrified bones sticking out of the side of the rocks. I found a rock just lying there that looks like a fragment of a skull bone. I put it in my suitcase and to this day it is sitting in my yard in Florida. I hope my yard doesn't get mistaken as an original dinosaur habitat someday, lol. I should probably use Zero's picture posting instructions and post a picture of it, but compared to what anyone can Google, my Dino pic would be very unremarkable

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.

I'm not sure ...

So if there ever was to be a new BB at the Farthest Edge of the Universe, how would/could We Observe it?

I was thinking that one possible sign of a distant BB might be a gamma ray burst.?

If WE cannot Observe/Measure it & there ain't no Data/Evidence for it, does it then mean it's Not Real?

I'd say no, though you do need some evidence to support a theory. But speculation can be fun, lol.

I guess it is what we make of it, but maybe if we were more brainy we could make more sense of it.

[Halc]

The Observable Edge of the Universe is drifting away FTL, Correct?

The size (radius say) of the observable universe is growing at a proper rate of a bit over 3c, and accelerating.

So if there ever was to be a new BB at the Farthest Edge of the Universe, how would/could We Observe it?

It just plain doesn't make sense for a big bang to occur at a location.  Also, there is no meaningful edge of the universe. I cannot think of a viable model that has one.

If WE cannot Observe/Measure it & there ain't no Data/Evidence for it, does it then mean it's Not Real?

By many definitions of 'is real', correct. Careful, since there is a distinction between measuring something and knowing about it. The latter implies nothing can be real without something that can 'know' about it. The measurement definition is simply any interaction between two systems.

I'd say no, though you do need some evidence to support a theory.

That you do, but a definition of 'real' isn't a theory, it's just a definition. The whole concept of 'real' is a metaphyscial one, so I don't think it is possible to produce conclusive evidence for a metaphysical conjecture. If one could, it would be a theory and cease to be metaphysics.

[Zer0]

Then what happens if there are really " Multiple Universes " but no way for Us to observe, measure or obtain any evidence for Them?

P.S. - Sorry to have sounded Metaphysical...
I won't go there again.
