I really ment "all math constructs" ...
But I see why I didn't ace the test - I bobo'd on the subjective 🙂
....
All math constructs don't describe reality.
OK?
A search happen to hit both aspects of this sub-disucssion :-D

Recently, I read that Dark Matter WIMPs may have a mass as small as 1E-22 eV and as high as several solar masses. The lower value is within collider energy capabilities but the latter is impossible to achieve. Colliders have eliminated most (?) energies which they can produce.
Does Dark Matter really exist, or is it a scientific hypothesis favoured because it simplifies most cosmic hypotheses?

It would appear from your link, TNT, that the new XENONnT detector has proved more sensitive than its predecessors.
This offers greater potential for detecting hypothetical dark matter particles, as well as solar neutrinos.
More details of the Xenon Dark Matter Search Experiment are in the link below.

You've told us that one before, Steve. It's got no funnier with time! 😜

The survival of our best model of the universe, the Lambda-CDM model, depends on the existence of Dark Matter to explain the anomalous movement of galaxies.
An alternative would be to eliminate the need for Dark Matter by modifying our existing gravitational theory - as suggested by MOND (MOdified Newtonian Dynamics).
The JWST may reveal additional details of the movement of galaxies that help determine which model best describes their behaviour.
What a rank bad post by TNT, IMO. Sorry. 😡
A link provided without any reason, why should we be interested?
I have many demands on my Time. Dark Matter and Dark Energy are extremely interesting. I don't know if Axions, Right-handed Neutrinos or Black Holes are right.
But this sort of unscientific sloppiness should be banned if we are to make more Scientific Progress.
Sorry to rant. I am a proper Scientist and Mathematician. I base my ideas on Certainty, such as it is within Quantum Mechanics. In which the Schrodinger's Cat could be alive or dead.
Time for another terrific Physics Joke:
Two Librarians are examining the Library Floor:
"Why is it so clean?" says one.
"Well, we have recently employed a new cleaner called Kepler!" says the other.
"So how does that work?" says the other.
"Well, he sweeps out the same area each Night!" 😀
Need I explain it?

I think I post more On Topic at times than you do... ;-)
If only a link - be sure its not OT from me. I'm just saving your valuable time from unnecessary reading 🙂
Galu gets it!

It helps enrich the thread when someone like you, TNT, comes up with a link that is worth exploring.
Steve's latest link is worth exploring - see the attached image. 📷
P.S. I guess that not everyone reads the links in full, or even in part.
That's why I like to extract the relevant information for easier consumption. It helps me get my head around the link's content if nothing else!

You could not possibly be referring to moi?
You got yer links, and then you got yer links.
I get it, Honest!

All your comments Pete are so strange - I'v seen you communicate in a very good fashion in other threads but here you just dont make any sense...
Like 10214 - how did you think here... 1st: why do you think you where adressed? 2nd... isn't the saying: Honestly, I get it!

In 2001 A Space Odyssey the line should have been "Oh my God, it's full of galaxies!"
But it was before the Hubble Deep Sky thing, and they had no idea about the ubiquity of galaxies.
Right on benb! 🙂
On its release, I had the pleasure of seeing "2001" in all its immersive glory at the Glasgow Coliseum - Scotland's first, and only, Cinerama theatre.
Many in the audience seemed puzzled by the "it's full of stars!" ending while I - of course - understood it perfectly! 😉
