Phys.org / Light beam 'swims' upstream through a quantum fluid by violating Newton's third law

Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
