It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid, forming swirling vortex lines and stable rotating ...

Recent studies have suggested that vortices in ultralight dark matter halos could provide new insights into the formation of cosmic structures, challenging traditional models of galaxy evolution. A ...

(Nanowerk News) Lord Kelvin theorized in 1880 that stimulating a thin vortex line would produce a helical deformation, later known as a Kelvin wave. While these waves have been observed in classical ...

These are tiny, discrete whirlpools that each carry a fixed amount of angular momentum. The scientists used the nanoparticle "stones" to study the process of vortex reconnection, in which lines of ...

Researchers formed stable vortex knots in chiral nematic liquid crystals and used electric pulses to reversibly fuse and split them into different knotted forms. (Nanowerk News) The knots in your ...
