"Unbalanced Galaxies Illuminate Dark Matter's Velocity"
Researchers have developed a method to calculate the forces affecting galaxies in tidal cycles, aiming to find lopsided galaxies in the universe to study the velocity of dark matter relative to the galaxies. The speed of dark matter can be measured by observing how galaxies affect the trajectory of dark matter particles as they pass by, causing a phenomenon called dynamical friction. Identifying lopsided galaxies isolated from other influences is crucial for accurately measuring the velocities of dark matter, which could provide valuable insights for testing new dark matter models and understanding the nature of dark matter.
