Spacetime Symphony: Gravitational Waves from Merging Black Holes
Spacetime Symphony: Gravitational Waves from Merging Black Holes
Δημοσιεύτηκε στις 11 Δεκ 2016
Nov. 2, 2016 Dr. Lynn Cominsky (Sonoma State University) Gravitational
waves are predicted by Einstein's General Theory of Relativity. They
travel at the speed of light, but are much harder to detect than light
waves. On September 14, 2015, the Laser Interferometer
Gravitational-wave Observatory (LIGO) received the first direct
gravitational wave signals. The event that produced them was the merger
of two distant and massive black holes that were in mutual orbit. Prof.
Cominsky presents an introduction to LIGO, to gravitational waves and
how they were detected, and to the kinds of black holes that "make
waves."
