Imagine a cup of tea that doesn't obey the laws of physics, it pours out of the bottom of your cup while crawling up the sides to the top, and you'll have a pretty good picture of the ultracold phenomena of superfluids.

Wait if the superfluid never stops spinning does that mean there’s the potential for infinite energy?

Could dark energy somehow be a superfluid? Then it having no friction might explain why we’re having such a hard time finding it?
FlyingJukebox 25 days ago
Also fun fact, there's this microbe, ebola or ecoli I think , something that starts with e, when suspended in a liquid, and pressed between two slides, they self arrange, and they also become a superfluid!

cooling helium-4 to -270 degrees is a bug that the devs never found so they never patched it out.

MrFatilo 26 days ago
The problem is, this is not reproducible, this experiment has not been reproduced since the 60s and there is no modern footage of this phenomenon. Many think that this was just a fluke rather than a true quantum mechanical event on macro scale.

I wonder what would happen if someone took a container of superfluid Helium-4 and compressed it. I'd assume that at least some of it would escape through the usual cracks... but would this compression reheat the superfluid helium, and what would happen? Would it stop behaving like a superfluid? Would the container explode apart, or would the superfluid just all squirt out like a tank of water with a hole in the bottom?

Oh my god, wait. . . if space time is a superfluid, does that mean Dark Matter is a superfluid? Being frictionless WOULD explain why it barely interacts with anything . . .

Why does food go stale? Is it the food going off due to microbes? Or is it some weird food reaction that happens in air, and for lack of a better example, like oxidation (food rust, which sounds just...horrible). Literally no idea. Anyways, excellent video on a pretty brainBr3Ak!nG topic :)

It would be nice, though, to get an updated video of superfluid helium. Any time I've looked it up, it's always that same very old video. I guess it'd be a waste of money just for the HD, but then it also wouldn't be a TOTAL waste of money...
