There is no speed limit in the superfluid universe

[John Clark]

Researchers report in Nature Communications that they found when Helium-3 is cooled to 0.0001K  a wire moving through it feels no resistance even when the wire is moving very rapidly. Lead author Dr. Samuli Autti said: "Superfluid helium-3 feels like a vacuum to a rod moving through it, although it is a relatively dense liquid. There is no resistance, none at all. I find this very intriguing."

The article says this discovery could aid in "studies of Majorana fermions aimed at producing components of, say, a quantum computer". Majorana fermions would be far less susceptible to quantum decoherence than normal particles and thus allow the construction of Topological Quantum Computers which, because of their much lower error rate, could be scaled up to arbitrary size.

In a sense with this superfluid an object moving through it does not bump into a lot of atoms. Since all the atoms are in an identical state, this object in effect only runs through one atom.
