Description
Speaker: Brett Bolen, Dept. of Physics, GVSU
On September 14, 2015, physicists at LIGO (the Laser Interferometer Gravitational-Wave Observatory) were able to directly detect the collision of two black holes, which occurred billions of light years away but just reached Earth at that instant. They did not use light in a traditional telescope but detected tiny vibrations in spacetime itself called gravitational waves, which were first predicted by Einstein in his Theory of General Relativity. In this talk, I will explain what gravitational waves are, how we can measure them, and most importantly how they will revolutionize our knowledge of astronomy.
