Unveiling Dark Matter's Identity Through Distorted Einstein Rings.

Researchers have analyzed several gravitationally lensed objects to determine the true identity of dark matter. By studying how light gets bent out of shape in warped Einstein rings, scientists have found that axions are a more probable candidate for dark matter than weakly interacting massive particles (WIMPs). Axions are minute particles that behave like waves due to quantum interference. Dark matter makes up around 85% of the universe, but scientists still have no idea what it really is.
