We Thought This Particle Was Impossible To Measure!

The #1 most-wanted particle in physics is the graviton, a quantum of gravity. If physicists were to prove that gravitons exist, they would unambiguously prove that Einstein’s theory is ultimately wrong and must be replaced by a more complete theory that gives quantum properties to space and time. In a recent paper, a physicist came up with an ingenious experiment that could prove that gravitons do exist. Let’s take a look.
