Discussion Overview

The discussion centers around the possibility of spinning superfluids to relativistic speeds, exploring the implications of their lack of viscosity and the methods that could be employed to achieve such spinning. The conversation touches on theoretical aspects and challenges related to superfluid dynamics and electromagnetism.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that since superfluids have no friction, they could potentially be spun faster until reaching relativistic speeds, although the method to achieve this is uncertain.
  • Another participant questions the feasibility of spinning a superfluid, noting that it lacks viscosity and that spinning the container would not result in the fluid spinning.
  • A participant proposes that if the fluid were a ferrofluid, it could be spun using electromagnetism.
  • There is a clarification regarding ferrofluids, with a participant referencing a source that discusses how ferrofluids polarize in a magnetic field but do not create vortices like those in supercurrents.
  • Concerns are raised about the relevance of ferrofluids to the discussion of superfluids and the methods proposed for spinning them.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of spinning superfluids and the relevance of ferrofluids to the discussion. The conversation remains unresolved regarding the methods to achieve the proposed spinning of superfluids.

Contextual Notes

Participants highlight limitations in understanding how to spin superfluids due to their unique properties and the lack of viscosity. There is also a dependence on definitions related to superfluids and ferrofluids that remains unclarified.

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?

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.
