    Does Babel Library contain the description for all Babel Images?

    So guys, here is my doubt: I know that the babel library contains everything that can be expressed through words, right? Every possible combination for a 32 hundred characters that will, if put together, contain all that can be said and therefore, described. Now, I know that there is also an equivalent to the library with images, and reading about it, I've come to this: The babel library image archives has ~10^(961755) images while the library has 10^(4677) books, which is waaaaaay less than the total number of images. Now, the questions:

    1 - Intuitively i know clearly that the library should not be able to describe every image in the archive since the difference in number of images and books is gargantuan, but than again, shouldn't it be able to describe anything that can be expressed in words and, since the images can be expressed in such form, shouldn't it contain their description?

    2 - If indeed the library cannot describe all the images, I'm pretty sure that the image archive itself will contain images of pages that describe itself entirely and here comes the first two problems I see: If there is an image of a page describing an image that was not in the library, it creates a paradox, right? If there is a way to say that, it should be contained within the library, right?

    3 -  Accepting the idea that the archive contains descriptive pages that describe itself (the archive) and are not contained in the library, that page should have a descriptive page for itself (inside the archive) and the page that describes it should also have a descriptive page that would, in my perception, loop to infinity, right?

    Can someone please explain to me what is going on here? Thanks in advance.

    If you really want a cursed temparature scale, how about gas mark. It's half linear half exponential (the inverse of a log scale) and gas mark 0 would be negative infinity degrees.

    Sooo close to 3000!

    Comic 3000 should release in just a few hours!

    Does anyone have any theories if it will be anything special, and if so, what?

    This gives me an idea

    Has anyone actually gotten a full XKCD comic as a tattoo? They could even get this as one.

    Did Randall ever endorse Biden the way he did Clinton and is doing Harris?

    https://preview.redd.it/2gpm3wez6ivd1.png?width=706&format=png&auto=webp&s=b6ba914f1109b70b7389ef8c9995b6ef83ae4f74

    Basically the title. There's a new site header endorsing Kamala Harris, which, just to be clear, I'm certainly not complaining about - he did the same thing with Hillary Clinton back in 2016, this isn't a surprise or shock or anything. I'm just curious, did he ever endorse Biden in the same way? I can't remember that, and if he didn't, I wonder why?
