Gravitational Waves - How the Bits of Quantum Gravity Can Buzz - Quanta Magazine

New calculations show how hypothetical particles called gravitons would give rise to a special kind of noise.

“There’s a kind of default consensus that it’s a waste of time to think about quantum effects and gravitational radiation,” said Frank Wilczek, a Nobel Prize-winning physicist at the Massachusetts Institute of Technology who was a co-author with Parikh on the new paper. Indeed, neither Wilczek, Parikh nor George Zahariade, a cosmologist at Arizona State and the third co-author, took the possibility seriously until after the 2015 discovery of gravitational waves by LIGO. “There’s nothing like actual experimental results to focus the attention,” said Wilczek.
