Hillsdale College Physics Alumni, Professor Participate in Groundbreaking International Research Work on Gravitational Waves

HILLSDALE, Mich.--(BUSINESS WIRE)--Hillsdale College Associate Professor of Physics Timothy Dolch and two physics alumni co-authored a study that discovered the existence of gravitational waves that oscillate slowly — some with a frequency of years or even decades. These gravitational waves, which were first hypothesized by Albert Einstein in his general theory of relativity, were observed in data acquired by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
