Cherenkov Radiation being emitted by the underwater core of the Advanced Test Reactor (ATR) at the Idaho National Laboratory.
The distinctive blue glow occurs when atomic particles become electrically charged and are accelerated beyond the speed of light, emitting photons in the process in a blue/violet spectrum.
Beyond the speed of light you say? Impossible right? In a vacuum, yes. But light travels much slower in water and it becomes possible for electrons and protons to actually move faster because water slows them down less.
Nice explanation of how it works

i wish today hadn't been so intense if only so i could put words to all the goddamn thoughts i have about the strange pale grey stone and the fucked up looking... research station? science building of some sort front and center on the gm screen.
especially in conjunction with the plasticy wrongness and the ozone smell that ava experienced, and the lightning from the ground that thorn saw.
there's SOMETHING and i'm going crazy and i love it

girl do charged particles travel faster than light within your medium because youre emitting a really sexy blue glow 😳

So this morning I realised that the Light is probably blue because of the Cherenkov effect
This is going to be badly explained but basically it’s what happens when a charged particle like an electron goes through a specific type of substance faster than light traverses that specific medium. Now an example of this effect that is used a lot is what happens to an underwater nuclear reactor: it glows blue!
Anyway I don’t know if someone’s talked about this before but I thought it was pretty neat :D

PHYSICS APPRECIATION: CHERENKOV RADIATION
I'm a student, enthusiast and massive nerd, this is my best attempt at sharing all the awesome little secrets and tid bits, beyond your average high school science class. (It's cool I swear).
In a visit to Sizewell power station last year (highly reccomend), I learned that nuclear reactors don't glow the radioactive green we see in cartoons:
But rather a brilliant blue:
It's cause is simmilar to that of a sonic boom. Normally, matter can't accelerate past the speed of light, however, the speed of light in water, is much slower than the speed of light in a vacuum (around 75%). This means that, charged particles emitted during nuclear reactions, are able to exceed the speed of light in their medium (water), and things get weird.
Water is dielectric (able to be electrically polarised), so when charged paricles faster than the speed of light travel through it, its particles become polarised. In order to return to their ground state, the particles emit photons.
The photos travel as waves with high frequencies and short wavelengths (remember ROYGBIV?), which tend towards the blue/violet end of the visible light spectrum, hence the blue. (And perhaps even ultraviolet, which we can't see).
If anyone wants me to go more in depth, or if I've made any mistakes, please lmk!!

Spoilers for Burrow's End: Episode 5 (Protect the Light) and Episode 7 (The First Stoats [latest]) under the cut
i am in agony
I read that theory on Tula's heart before, but augh, revisiting this line now to reconfirm it hurts so much in hindsight. I think it's mostly because BOTH parts are in some ways a lie. In some ways, Tula isn't here anymore; not to mention, even with Tula's guidance, Lila has only had her own heart the whole time.
it's fine everything is fine i'm fine
now who's gonna pilfer the Stoat Mitre off of The Faith's pulped corpse? that's the real pressing issue
