“I been to the edge. Just looked like . . . more space.”

More space and more space, “SPACE” being the something that all of those galaxies exist within.

What is there more of, galaxies or space?

And what is the something that the galaxies themselves exist within?

More space, all the something in each galaxy are all light years of space from each other.

And supposedly 95 percent of the observable universe / space is not even detectable because it is dark matter or dark energy?

Seems like a lot of space to me.

In reply to Cotour. Cotour: I am puzzled by your comment. The image shows exactly the oppose to what you say. It looks out and sees a lot of SOMETHING. There is more there then we have predicted or previously imagined. As my post's headline notes, galaxies without end. You however appear to be unable to see what is there right before your eyes. :)

We look out as far as we possibly can and we see a lot of ………….nothing.

Then we look in as far as we possibly can and we see a lot of…………… nothing.

And here we are sitting right in the middle asking “What the hell is going on!?”

There has to be something more that we are unable to detect or comprehend rather than nothing.

IMO anyway.

The Earth-centric model of the universe is back in vogue. We see stuff all the way out in all directions, which implies we are in the middle. There is a caveat: The visible universe. Because it’s the same in all directions, we now think that there is stuff that has red-shifted beyond visibility (JWST is helping with this, being infrared) and more stuff that has expanded away faster than speed of light (from our perspective) so even the Cosmic Background Microwave images don’t have it. Eventually (in trillions upon trillions of years), the Milky Way (and a couple of friends) will be the only visible galaxy as everything else expands out of our light bubble/volume.

I use “we” very generously. I have no opinion and have not seen any of it, personally.

Every time I drag out my 16″ Dob telescope under a clear dark sky I am reminded that indeed the scale of the Universe is simply impossible to grasp. It hurts my head but great to experience the awe.

I believe it has been established that we human beings have limitations and may not have the perception or the capacity to truly understand just how big and what the universe we are a part of, a direct function of, actually is.

Science can only get you so far.

I have alway loved the phrases “known universe” and “edge of the known universe.” Now that the Webb Space Telescope is seeing farther, we are discovering things that “shouldn’t be there.” That “universe edge” has moved. What is beyond the new “edge”? With this new information, scientists will hypothesize and theorize. Then there will be more new discoveries of what “shouldn’t be there.” When Hubble looked at that small “empty” portion of the night sky, we found billions and billions more galaxies. Before, we theorized there were about 200 billion galaxies. Now it is trillions. Does the “universe” have an end, an edge? I don’t pretend to know, bet it is a helluva lot of fun.

When you click on the original image and enlarge it, you can *see* all of the galaxies behind NGC 1309, a HST “Deep Field” shot in its own right.

As an aside, and with the James Webb Space Telescope now in service, I can’t help but wonder how many of Halton “Chip” Arp’s peculiar galaxies* have been resurveyed and what has been discovered about them. Prof. Arp was a wonderful “trouble maker,” especially as his observations called into question the standard models of cosmology, and I wonder — with new data from the JWST — how his anomalies might be interpreted today.
