Science on Screen!
Let's do the timewarp again at the Oriental Theatre - join us for a screening of Primer preceeded by a fascinating talk from Joseph Swiggum, a Postdoctoral Research Associate at the Center for Gravitation, Cosmology, and Astrophysics at UWM. He will delve into the fascinating topic of Spacetime and how detecting gravitational waves helps us understand the way galaxies form, interact, and evolve.
Primer - When two small time engineers accidentally create a time machine, their friendship is put to the test as they attempt to use their discovery to change their lives.
An initiative of the Coolidge Corner Theatre. With major support from the Alfred P. Sloan Foundation.
More from Joseph Wiggum:
"Measuring the passage of time depends on the circumstances in which the measurement is made. A clock in motion is observed to tick more slowly than another at rest; clocks in strong gravitational fields also run slow. These are consequences of Special Relativity and General Relativity, theories first proposed by Albert Einstein in the early 1900s. A century later, a key prediction of General Relativity was confirmed when LIGO (the Laser Interferometer Gravitational Wave Observatory) detected gravitational waves - ripples in spacetime - generated in the final moments of two black holes' merger. A complimentary experiment, NANOGrav (the North American Nanohertz Observatory for Gravitational Waves), uses cosmic clocks, pulsars, scattered all over the Milky Way to detect gravitational waves from colliding galaxies. These detections will enhance our understanding of how galaxies form, interact, and evolve."
