But that's only a guess. Still, whatever it is, it must hold some clues as to the history, as well as the overall evolution of the universe. In other words, any theory hoping to explain the origin or fate of the cosmos must also be able to explain this structure we are seeing. In a way, this is good news. If the universe is totally homogeneous and uniform at the largest scales, it doesn't give us much evidence for us to speculate with. The local TV station just got a fancy new high-tech weather radar, and the imagery we've been getting on the evening news every night is much more detailed, and of much higher resolution. We're starting to see all sorts of features and structures that weren't available with the old radar system. Instead of just blobs and rough shapes, we're starting to see all kinds of fine structure that wasn't visible before, and sometimes these features are obviously interacting with thunderstorms, fronts, etc. One of these features that we weren't aware of before is thin arcs of light precipitation emanating from thunderstorms, sometimes precipitating other storms as they flow, like shock waves, through unstable air. We're not just watching fronts of corps and divisions moving and colliding through the atmospheric battlefields, now we can see down to the brigade, battalion and company levels. I can't wait till hurricane season really gets underway so we can get a clearer look at what's going on inside these big tropical systems. New data is always exciting... My guess is the large-scale structure of the universe is somehow the result of the first few moments of the Big Bang, that these filaments, threads and voids were artifacts of the initial explosion.

I can’t wait till hurricane season really gets underway so we can get a clearer look at what’s going on inside these big tropical systems.

New data is always exciting…

How about ironic? I’m referring to my reply to you, ER, toward the bottom in Buck’s long-threaded “Interesting Article on Advanced Aerospace Threat Identification...” posting (May 13, 2021 | 2:32 pm). “Been a while . . . by DanS 2021-06-16 15:26:42” This episode involving “the biggest spinning object in the universe” is impressive. Here we have a few thousand galaxies revolving around each other and forming a kind of twisted line of rope. Those anomalies are very far away and really, really big (“hundreds of millions of lightyears long”). Could the answer be as simple as clean gravitic forces at work without interference? Generally speaking, galaxies drawn together are said to collide eventually, but what happens when gravitic polarities are realigned? Might a spinning rope of galaxies the solution? The universe is the only laboratory large enough to display such an event, but doing the research will take many generations. These are intergalactic oddities for which we have no real answers, all of which are “self-demanding for research.” Buck’s posting, though, was of events occurring a lot closer to home. As technology improves, so does the picture of the perceived universe around us, but this by no means implies we understand what it is we’re seeing. “Quantum entanglements with the properties of dark energy and dark matter? Nature does strange things, often more bizarre than anything of which humanity is capable. We have no idea what any of this is, but I find it all self-demanding for research.” Okay, maybe not very funny. How about ironic?
