@@rj6110 I'm taking biochem too, but it doesn't mean it isn't cool. Some of the fun parts of chemistry are usually the parts that don't involve a ton of explanation, they're just cool experiments.
I believe using super fluids, specifically infinite thermal conductivity, as a conduit for transport of high energy would allow for longer distance transfer at basically no loss. Idk :/ A battery would also be ideal.
Although it's conductivity is infinite, it's heat capacity is pretty low so I don't think it would be the best way to transfer heat. There's also the fact that you would have to keep the entire system at ~2 K, so it would be very inefficient.
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

A bold suggestion: dark matter is a helium-4 superfluid (or a superfluid of similar properties), which is why it fills the intracluster medium (where it is just a bit warmer than that of the intercluster), and dark energy is a helium-3 superfluid (again or a superfluid of similar properties), which is why it fills the intercluster medium (where it is just a bit cooler than that of the intracluster medium.)

A bold suggestion: dark matter is a helium-4 superfluid (or a superfluid of similar properties), which is why it fills the intracluster medium (where it is just a bit warmer than that of the intercluster), and dark energy is a helium-3 superfluid (again or a superfluid of similar properties), which is why it fills the intercluster medium (where it is just a bit cooler than that of the intracluster medium.) I'll take my Nobel prize now, thanks
