In 1915 Albert Einstein’s General Theory of Relativity predicted there would be measurable gravity waves. One hundred years later they have been detected. This opens the door to new ways of studying gravity and the universe.
Quoiting news releases:
The gravitational waves were detected on Sept. 14, 2015 at 5:51 a.m. Eastern Daylight Time (9:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA.
My first question is what’s a LIGO? (lī•gō)We know what a laser is, a device that produces collimated, monochromatic, and synchronized light, synchronized with itself. The meaning is each light wave is in step with all its sister waves, all waves are the same length, and all are going in the same direction, parallel. (Reference)
