For many years, nobody has known what gravity is, a force, or a wave. A century after being theorized by Albert Einstein, scientists have discovered gravitational waves (D news). This detection was by the twin LIGO interferometers on September 14, 2015. After over 100 years of searching, it has been confirmed. Gravity is a wave!
Gravitational waves are alike to sound waves (Science Alert). Gravitational waves are believed to travel at the speed of light. These waves are rumored to be the result of black hole collision. Because of all the variables (such as traffic) it is difficult for detectors to confirm the prescence of gravitational waves.
Experts are already saying that this discovery is a shoo-in for the Nobel Peace Prize, and this breakthrough is sure to change scientific research forever.
