All women are invited to attend Savvy Women Exchanging Relevant Views (SWERV) to hear professional engineers Frank Petrie and Jim Thrash explain the recently detected disturbance in the space-time continuum caused by two neutron stars crashing together as detected by the Laser Interferometer Gravitational Wave Observatory (LIGO).

The presentation is called “LIGO: How to Catch a Gravity Wave.”

Petrie is active in the Battle Point Astronomical Association and Thrash helped procure the LIGO construction project for his former employer.

So what is LIGO? What did it find? Why is this important? Learn how LIGO provides a glimpse into the strange world of Einstein’s general relativity, confirms a 100-year-old prediction of gravitational waves, and opens the door to the new field of gravitational-wave astrophysics.

SWERV meets from 10:30 a.m. to noon Tuesday, Oct. 9 at Filipino American Hall, 7566 High School Road.
