And this is actually something that we see a lot in stellar atmospheres because stellar atmospheres have a lot of ionized hydrogen. This is a blueprint of a blue super giant spectrum. And there you can see right at about >> uh that Balmer limit, you're going to get a massive discontinuity. >> Yes. >> Where there's a bunch of stuff at a higher wavelength because those photons don't have enough energy to ionize hydrogen. But the stuff that's with a smaller wavelength, so higher

    JWST's "Little Red Dots," TimeVaults, and the Dawn of Math

    Little Red Dots, TimeVaults biology, and ancient math in Halaf pottery.

    JWST's Little Red Dots and the early black-hole puzzle, Harvard/Broad's TimeVaults for time-series gene expression, Halaf pottery that may encode geometric sequences—and a quick Cloud9 dark-halo follow-up.
