"Study Reveals Dark Matter's Potential Collisional Properties"
A new study published in Astronomy & Astrophysics suggests that dark matter may have collisional properties, challenging the standard model. Using numerical simulations of the galaxy cluster "El Gordo," researchers found that the observed separation between dark matter and other mass components can be explained by the Self-Interacting Dark Matter (SIDM) model, indicating that dark matter particles might exchange energy through collisions.
