The current theoretical model for the composition of the universe is that it's made of normal matter, dark energy and dark matter. A new University of Ottawa study challenges this.
Don’t get too excited, this is a pretty fringe theory that doesn’t really have experimental evidence. They were able to make some observations fit with their theory without dark matter yes, but not all of them. The tired light part in particular has a lot of contradictions with observation that they don’t explain.
I’m a workshop kind of guy that enjoys space documentaries. For my part, I see “dark matter” as a known hole in our current understanding of cosmology, and I bet when we figure out how it does actually work it’ll lead to some really cool TV shows.

So interesting, but far from definitive.
Couldn’t the same be said for the proof of dark matter?
No, dark matter is actually a great explanation for lots and lots of observations; the only problem with it is that we don’t know anything about it other than that it is such a good explanation for these observations.
Generally for a new theory to be accepted, it needs to explain everything that the old theory did plus something more
If light got tired, wouldn’t everything get blurry the further away it were?
I’m nearsighted, so that happens anyways
Me too but I always knew that it was my eyes not the maximum draw distance of the universe that was to blame.

I get what you’re saying, but peer review isn’t exactly all that rigorous either

Thats not what the posting claimed to be. You missunderstand. Either intentionally or just as a fact.
