Beyond the famous spatial separation between gas and lensing mass in the Bullet Cluster, detailed analyses have revealed subtle offsets and asymmetries in the mass distribution that are difficult to explain within the standard collision-less dark matter paradigm. Observations suggest that the lensing mass peaks are not perfectly aligned with the galaxy distributions, showing small but persistent offsets of a few to tens of kiloparsecs, and the mass-to-light ratios vary across different regions of the system in ways that are not fully predicted by simulations of colliding dark matter halos (Bradac 2006; Lage 2012). Lambda-CDM struggles with these fine-scale mass distribution features because while the model successfully predicts the gross separation between collisional gas and collision-less dark matter, it has difficulty explaining the detailed substructure, asymmetries, and slight misalignments between the collision-less components themselves—galaxies should trace dark matter very closely if both are collision-less, yet the observations hint at more complex dynamics than simple gravitational passage allows.
