Seeing Light, Hearing Gravity: Searching for Gravitational Waves with Joel Franklin, PhD, Assistant Professor of Physics at Reed College

If you take an electric charge and move it around, electromagnetic radiation (“light”) is generated. Similarly, if you take a massive object and move it around, gravitational radiation is generated. While electromagnetic radiation is ubiquitous, occurring both naturally and from human sources, gravitational radiation has only recently been detected directly by the Laser Interferometer Gravitational-Wave Observatory (LIGO). I will discuss the LIGO experiment and its target sources, in addition to the difficulties that plague direct gravitational wave detection.

More generally, Joel will talk about the nature of electromagnetic vs. gravitational radiation, focusing on their similarities and differences, and the broader predictions about gravity that can be made by exploiting its structural similarity with electromagnetic interactions.
