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.

They could also urge to remove the coat and tie from the list of necessary clothes. While it was probably practical in 19th century England, it's a torture in 2023 Spain
Just lovely, when you think you found a browser that works decently and cares about privacy...
I just checked Lemmy stats - how is it possible that we lost 400 000 users recently? If people check it out and leave for good, wouldn't that still be counted in the user base?
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)
What if you sell everything and work for 237 more years?
Has anyone tried this? What are your opinions?
I didn't say this happened yesterday :)
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
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.
So, like achieving the goal twice?

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.
