6. Dark Matter in the Bullet Cluster
Year Found: Mid 2000s
Who Found It: A group of astronomers from NASA
Location: The galaxy cluster 1E 0657-56
Alternative explanations are beginning to look more appealing, as there is currently no specific and convincing experimental evidence to support what kind of particle is responsible for dark matter. But over the past 16 years or so, it has become way clearer, though, how dark matter could possibly affect the motion of stars and galaxies.

It should be noted, though, that a group of astronomers measured the mass of the Bullet Cluster in the middle of the 2000s and discovered that, even when using a different theory of gravity, the distribution was somewhat different from what was originally predicted with only the basic and normal matter. This result confirms in this case that dark matter is real.
