Dark matter, which makes up about 85 percent of all matter in the universe, is invisible to telescopes as it neither emits nor absorbs light.
Recent research suggests that dark matter could behave like a cosmic superfluid, forming swirling vortex lines and stable rotating cores known as solitons inside galaxies.
It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid.
The study draws parallels between the quantum world of Bose–Einstein condensates (BECs) and the grand cosmic scales of dark matter, potentially reshaping the understanding of the cosmos.
Traditionally, scientists have described dark matter as a collisionless fluid of particles, non-interacting and cold, known as cold dark matter (CDM).
Author's summary: Dark matter may behave like a cosmic superfluid.
