What's dark matter?
Dark matter is one of the most important mysteries of physics. Scientists believe in its existence based on the law of universal gravitation, but have never directly detected it.
Accounting for over a quarter of the universe's mass-energy balance, it can only be observed indirectly through its interaction with visible matter.
