Did We Just Solve Quantum Gravity?

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/1Nm0Qc8... On a quiet Sunday in October 2022, a detector beneath Mount Elbrus recorded one particle of light carrying 300 trillion electron volts, sent by the brightest gamma-ray burst ever seen. The ancient light filling space should have erased it before it reached us, and it arrived more than an hour after the burst had faded. What lets one photon do that? Tonight we follow it slowly, through a fog made of light, past the experiment that buried the aether, and down toward the grain that space itself might have. Get comfortable and let this slow walk through one impossible photon keep you company tonight. Subscribe to Nap Theory if you enjoy the long way around the universe.
