…there are two different ways to measure this cosmic expansion rate, and they don’t agree. One method looks deep into the past by analyzing cosmic microwave background radiation, the faint afterglow of the Big Bang. The other studies Cepheid variable stars in nearby galaxies, whose brightness allows astronomers to map more recent expansion.

You’d expect both methods to give the same answer. Instead, they disagree—by a lot. And this mismatch is what scientists call the Hubble tension…Webb’s data agrees with Hubble’s and completely rules out measurement error as the cause of the discrepancy. It’s now harder than ever to explain away the tension as a statistical fluke. This inconsistency suggests something big might be missing from our understanding of the universe - something beyond current theories involving dark matter, dark energy, or even gravity itself. When the same universe appears to expand at different rates depending on how and where you look, it raises the possibility that our entire cosmological model may need rethinking.

    Cool.

    Also, what do folks use to block ads on mobile. I’ve been using FF with Ublock Origin, but lately it hasn’t been cutting it.

      I use a pihole when I’m home, and ghostery browser for link handling when I’m out. It’s incredibly basic so not great for a primary browser, but has Adblock and tracking protection, plus auto-declines cookies, so great for link handling. (I could set up a vpn but I’m incredibly lazy)

      I don’t think ghostery browser is still maintained, but because it uses the same lists as their Firefox extension, it still works like a charm.

      Also if you want to keep using Firefox, you can try the ghostery extension as well, assuming you are on android where that’s an option (I’m not which is why I use the browser)

      Brave, yes the CEO is a piece of shit and it has some suspicious crypto stuff but whatever if it keeps the company afloat. The browser itself is good, the best mobile browser I’ve used. Don’t give the company money in any way however.

      DNSNet, it’s a FOSS app on F-Droid, works on pretty much all apps, as it acts like a vpn but runs entirely locally.

      I just use the adguard dns IP as my private dns router. I know it’s not the best way, but it works for me. No ads anywhere on my phone.

      Check which blocking lists you have. I use the same and don’t see any ads

      The internet is also becoming advertising hell. I go to a website to read a 400 word article or blog post and my browser will take one or two minutes to load as it tries to remove ads, cookie requests, pop-ups, redirects, videos, or any other additions … so that I can spend two minutes reading the content that I want. About 20% of the time, the site breaks or doesn’t even appear, so I skip it and move on after having spent 4 minutes wasting my time.

          At least two or three times a week my wife will ask me about a website she saw on Facebook … and the site you just showed me is the type of crap that would appear.

          The internet is slowly filling up with nonsense websites with psueodo information that is driving down human intelligence … all in an effort to gain a few pennies in advertising.
