Bullet Cluster
= Bullet Cluster
{c}
A merging <galaxy cluster> exhibiting the <bullet Cluster dark-matter separation>: peaks of <weak gravitational lensing> <mass> lie nearer the galaxies than the displaced <X-ray> gas. Combining the components supports a dominant less-collisional gravitating component under the usual gravitational model.<A direct empirical proof of the existence of dark matter by Douglas Clowe and others>[Abstract and spatial comparison of the observed components]{ref}
