100 Years of Quantum Space-time: from Theory to Experiment

More than 100 years ago, the basic laws of quantum mechanics and Einstein’s theory of general relativity were discovered almost simultaneously. It was quickly recognized that combining these theories implied that space and time itself should also follow the laws of quantum mechanics. Yet, for much of the past century, testing this idea experimentally was considered science fiction.

In this talk, Dan Carney will explore three transformative developments in the past two decades that have dramatically shifted this perspective. First, the 1997 discovery of the accelerated expansion of the universe, which has forced theorists to re-think what quantities can be observed even in principle, due to the presence of cosmological horizons. Second, the development of the quantum computer, which may allow us to perform simulations of our only self-consistent, detailed model of quantum gravity: string theory. And finally, the advent of advanced quantum detectors, which are now so sensitive that they will soon be capable of directly observing quantum states of the gravitational field itself.

This winter, we will host our public physics talks in Flug Forum at Aspen Center for Physics. Join us starting at 5:00pm for tea and cookies before each talk. The talks will begin at 5:30pm sharp. There is free parking at the Center and in the neighborhood. We also recommend taking the Downtowner or the free RFTA Crosstown Shuttle.
