Spinning Super Fluids: Reach Relativistic Speeds?

[AKatawazi]

Since there is no friction on a super fluid, can they be spun faster and faster until they reach relativistic speeds? I'm not totally sure the method you would use to spin the fluid, possibly electromagnatism somehow but assuming it were possible.

Er... how do you propose you get it to spin? It has no viscosity. So if you spin the container it is in, it still won't spin! And this is not a supercurrent, so EM interaction doesn't cut it.

Well if it was a farafluid it could be spun with electromagnatism right?

A what?

Sorry spelling a Ferrofluid or http://en.wikipedia.org/wiki/Ferrofluid for reference

 

[ZapperZ]

Well, if you also look at that reference, you would have noticed that it says that a ferrofluid in a magnetic field causes the fluid to polarized along the field. It says nothing about creating any kind of vortices similar to what you get for a supercurrent.

So I still fail to understand why this is relevant here, and how you intend to spin your superfluid.
