Dark matter behavior may conflict with our best theory of the universe

New research shows a direct interaction between dark matter particles and those that make up ordinary matter.

A new paper, published in the Astronomy and Astrophysics journal, discovered unexpected characteristics for the elusive dark matter that likely goes against our best theory of the universe – the Lambda-Cold Dark Matter model. 

What is dark matter?

Dark matter is a hypothetical form of matter that scientists believe makes up about 27 percent of all matter in the universe and accounts for about 84 percent of its mass, according to NASA. We haven’t been able to detect this type of matter directly yet as it does not emit electromagnetic radiation or scatter light. Still, scientists have inferred its existence from its gravitational effects.
