Dark matter, which makes up approximately 85% of the universe's matter, is invisible to telescopes as it neither emits nor absorbs light.
Recent research suggests that dark matter may behave like a cosmic superfluid, forming vortex lines and stable rotating cores, known as solitons, within galaxies.
It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid.
This theory draws parallels between the quantum world of Bose–Einstein condensates and the grand cosmic scales of dark matter, potentially reshaping our understanding of the cosmos.
Author's summary: Dark matter may be a cosmic superfluid.
