Limits of Reality: Time and Space on the Largest and Smallest Scales
Listen now
We all learn about space and time as children, yet they are still profound mysteries at the cutting edge of physics research. This session surveys several current experiments that probe exotic behavior of space and time: a "Dark Energy Camera" to study the accelerating expansion of cosmic space; laser interferometers that listen for gravitational waves from black holes; and the Fermilab Holometer, an experiment to search for universal "holographic noise" from the quantum nature of space-time — the bandwidth limit of reality. Craig Hogan is the speaker here.
