Article proposes variant of current ΛCDM cosmological model that makes the universe twice as old
  • Wikipedia is a good starting point: https://en.m.wikipedia.org/wiki/Age_of_the_universe . I'm not an expert on the topic, but if I'd like to dig deeper, I'd visit Amazon, look for cosmology books, pick something that's expansive, looks like a textbook, plus point if the title contains the word 'introduction' (you'll see the irony inside). It's the best if you find something from after 2010 (after Planck and WMAP missions). I found Weinberg: Cosmology, but that's from 2008. If you have your favorite textbook, check it out from the local library, but make sure NOT to download it from Library Genesis (http://libgen.is/ is the site to avoid) because that would cause the publisher financial losses.

  • Age estimation is a tricky thing - there are no brass labels on distant galaxies showing their age, or if there are, the letters are too small to see. There are several different methods, and while there's some disagreement between them, it's on the magnitude of 0.1Gyr, not 13.7+/-13.

  • How do computers make any color using red/green/blue, when paints make every clor using red/yellow/blue?o
  • Basically there are two color models, additive and substractive. RGB is additive - turning on red it triggers the red receptors in the eye. If you turn on all three it triggers all your color receptors and you'll see white. That is all the visible spectrum, if you look at the Sun (which you shouldn't) you perceive it as white even if the maximum of the emission is at green.

    When mixing paint (subtractive model, like CMYK on printers) if you mix all colors, they absorb different part of the light and don't reflect anything visible for you, and you'll see black(ish)

  • Bulgaria and Romania should be in Schengen by end of 2023, says Parliament
  • If I remember correctly, the last bulk addition of countries happened sometimes in summer, we traveled to the Czech republic with a passport on Friday, and came back without it on Sunday, and it was definitely not a New Year

  • Threads, Mastodon, and the Loneliness of Social Media
  • Great, few more reasons to stay away from that. I thought the whole point of the reddit/fediverse thing was that you used an anonymous nick that is purged from time to time. Who cares about followers? There are interesting things discussed, that's it.

  • What's the worst thing you've ever smelled?
  • For me there are two strong ones competing: Hákarl, basically fermented rotting shark – this smells like a Serbian railway toilet during the war, when it wasn't cleaned for years, but used regularly. It tastes the same. The other was a dog carcass, that was left on the roadside on a nice, hot summer day, and the 'not my job' mentality left it there slowly decomposing over roughly two-three weeks.

  • ELI5: How do you play Dungeons & Dragons?
  • Just a small addition to the other comments, who kinda wrote already everything that's important - for your first play try to look for an experienced dungeon master (that might be a good idea independent of the actual meaning of the phrase), it might kill the mood if everyone is trying to figure out the rules at the same time

  • Evernote alternatives?
  • Thanks! Nextcloud could be a good solution, given that we already have that server running – do they have an app inside or just a text file? I'm not the admin of that cloud, so can't check any extra options personally

  • Evernote alternatives?

    With their recent update it seems they are on the last step to making their free version completely useless – are there any good alternatives out there? Preferably something that has a similar android app. I know I could use ssh+vi in a text file, but I'd prefer something a bit more streamlined
