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.
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…
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)
Has anyone tried this? What are your opinions?
Any turn-based strategy game could be good - you can stop playing Civilization any time you want, right? There’s no need to go one more turn
