The video in the link claims the New Horizons probe now out past Pluto is finding more light than expected (twice as much!) ... "and it's not due to stars, but rather from between them", the video claims. So the reason they might be seeing more light is due to axions, they say. Yeah ... that's right ... the particle that I just posted about them NOT finding so far. But, according to the video, axions with a mass between 8 and 20 electronvolts could create all this extra light. I decided to investigate further and did confirm what the above reported. New Horizons has found more light than expected and, hot off the press, scientists are now suggesting axions are the cause (https://journals.aps.org/prl/abstract/1 ... 129.231301 ).Scientists: Why there's more light than there should be in the universe
And it might have to do with dark matter.
They probably are going to ask for lots of money to study that.
Hmmmm ... I wonder if there is any other reason the universe might be twice as bright as they expected?
Well for one ...

The above article concludes“It turns out that the galaxies that we know about can account for about half of the level we see,” says Tod Lauer, an astronomer at the National Science Foundation’s NOIRLab in Tucson, Ariz.
And guess what? JWST has found a lot more galaxies than they expected.There are several astronomical reasons that could explain the discrepancy. Perhaps, says Postman, rogue stars stripped from galaxies linger in intergalactic space. Or maybe, he says, there is “a very faint population of very compact galaxies that are just below the detection limits of Hubble.” If it’s the latter case, astronomers should know in the next couple years because NASA’s recently launched James Webb Space Telescope will see these even-fainter galaxies (SN: 10/6/21).

There were 10 times more galaxies just like our own Milky Way in the early Universe than previously thought.

Astronomers had estimated how many galaxies they might find at these distances, but in JWST's observations to date, candidates are proving more plentiful than expected. ... snip ... "These galaxies we're talking about are bright, and so they were hiding, just under the limits of what Hubble could do," she added.

The galaxies' incredible light output is a puzzling thing. They are either filled with many small stars, making them extremely massive; or, they have fewer, but much larger stars. These more massive stars could be the fabled Population III stars, the first stars that ever shone in the universe, which we are yet to see and that JWST is going to look for.

Intracluster light is less than 1% of the brightness of the darkest sky on Earth but JWST can help us see it.
JWST has seen intracluster light (ICL), the very faint emission produced by stars pulled out of their galaxies as these cosmic islands interact inside a cluster. Seeing this light has big implications not just for understanding the evolution of galaxies and galaxy clusters, but also for a mystery crucial to our whole understanding of the cosmos.
