Invisible Vortices of Dark Matter ⚡ экспресс
Original: "BEC vortices as an observational signature of ultra-light bosonic dark matter"
Giant vortices of ultralight dark matter might betray themselves by a regular pattern of bright spots in the sky.

If dark matter is a superfluid condensate, each galaxy might harbor giant invisible vortices. They can be spotted by the distortion of light from distant stars — just as ripples on water reveal underwater currents.
🎯 Vortices in superfluid helium can exist indefinitely; analogous dark matter vortices can persist for billions of years.
