Phys.org / Tiny objects swimming in a superfluid of light move against the flow

Superfluids are intriguing states of matter in which particles behave like a giant collective wave, allowing them to flow without any friction. When this fluid flows past a fixed obstacle at a velocity below a specific threshold, ...
