Dark matter avoids collapsing into a single point due to its non-zero velocity dispersion and pressure
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Astrophysical studies examining dark matter dynamics confirm that velocity dispersion, quantum pressure, and self-interaction effects counteract gravitational attraction, preventing dark matter from collapsing into a single point.
