screen-shot-2016-10-07-at-10-09-15-amThe Winona State University Geoscience Department Earth Talks Speaker Series will host Demian Cho to present “Gravitational Wave Astronomy: Hearing Wiggles of Spacetime” at 4 p.m. Monday, Oct. 10, in the Science Laboratory Center Auditorium, room 120.

Cho will speak about the detection of the first gravitational wave signal from a system of binary black holes known as GW150914. Cho will describe what a gravitational wave is, how it is detected and why many people find the discovery to be exciting.

Cho will also discuss how science explains gravity as curvature of space and time and the engineering feat that was required for the discovery.

Cho is an assistant professor of physics at Saint Mary’s University of Minnesota. Cho studies and researches relativistic astrophysics and spacetime physics.

This event is free and open to the public.

The Earth Talks series serves as a forum through which experts from academia, government and the private sector, as well as WSU students and faculty, share their experiences and research results with the WSU geoscience community. The series also provides a venue for discussions of professional, educational, employment issues related to geology, natural resources, Earth science teaching, and other related disciplines.
