About six months ago, scientists got excited about the potential detection of direct evidence for the event known as "cosmic inflation." Then team of scientists claimed to have detected an imprint in the cosmic microwave background that could have been created by gravity waves resulting from cosmic inflation.
If confirmed, the recently detected potential ripples from the Big Bang represent an imprint on the cosmic microwave background by gravitational waves. Those gravitational waves are produced through a quantum process, providing, for the first time (again, if confirmed), evidence that gravity is governed by quantum mechanics. This point cannot be overemphasized.
