While it may be true that a super fluid is frictionless, it would be wrong to say that it would continue to stir if placed in cup and stirred. It will eventually slow down due to the friction against the wall of said cup.

Dumb idea, but maybe you guys could think of doing a special episode or panel on the topic of pursuing a career in science. I'm sure there are plenty of viewers who are high schoolers, early college students, and early career people who would love to learn more about how to get into different fields. Topics of interest might include: the general (with lots of caveats) career progression they can expect (e.g. undergrad -> PostBacc? -> grad (MA/MS/PhD) -> PostDoc -> Adjunct? ->...), tips for getting involved in labs while in undergrad, etc. If you keep it general enough, I'm sure many of your supporters will find it super helpful!

[@louislamp]

Something you said about how every atom begins to move together when they are in the same energy state has a macro scale analog. Start a ton of metronomes on a moveable platform and they will work themselves into synchronicity (plenty of vids of this), and you can consider the 'orbit', vector and position of all of the electrons in the superfluid to likewise synchronize quickly. Even though an electron's mass is a MUCH smaller than a metronome's weight, they are cycling at around how many millions or billions of times per second? This makes up for the disparity in mass by a lot.

I know about the whole discrete energy levels thing, but when a particle transitions to another energy level, what does that look like? If we were measuring its energy state continuously, would we see any sort of fluctuation around a given state as the particle "passes through the space" between levels? Or does the particle really just jump, in an apparent instant, from one state to the next? Or are the possible states generally so numerous that on a macroscopic level, they appear smooth and continuous even if they are really making, for all intents and purposes, quantum leaps?

I learned about superfluids a while ago but they are amazing it’s almost like they have super powers. Edit: I can’t spell

[@DanielWSonntag]

I was totally wondering about that

[@noyadishon6649]

this is incredible

[@joshuab4586]

Wait wait wait, you can’t just say “space-time might be a superfluid” and not elaborate how that scales, like points in space-time are frictionless? Or multiverses are? Or like the fabric of space-time is actually a superfluid? Or everything down to quarks or strings are frictionless and don’t interfere with each other? I need an answer

[@sarararah18]

I also need an answer. I also am disturbed by the idea that there is no place in the universe where helium exists in a solid state.

BUT WHO IS THIS ADAM THEY KEEP REFERRING TO ?

Thanks!

Basically a superfluid is a bunch of molecules/elements whom under the right stressors have a main goal to keep their distance and respect the space of other molecules/atoms in the hopes the same courtesy is reciprocated thus creating what we observe as a super fluid. If there ever was a case for minding your own business scientifically, this would be it
