“Star Wars” Test of Einstein’s Prediction of Gravity Waves Using Three Spaceships and Lasers

Starfire-optical-range-laser3 Fifty-five years after Albert Einstein's death, physicists will be testing his prediction of gravity waves in his general relativity theory. Three spacecraft flying 3million miles apart will fire lasers at each other, overseen by Nasa and the European Space Agency.

Using the largest scientific apparatus to ever be built, we'll finally discover if gravitational waves actually exist. The laser beams won't harm the spacecraft, which will be carrying floating cubes of gold platinum, instead they'll be used to measure the changes.

A Glasgow University professor by the name of Jim Hough told The Telegraph that gravitational waves "are produced when massive objects like black holes or collapsed stars accelerate through space, perhaps because they being pulled towards another object with greater gravitational pull like a massive black hole."

So, why bother with all this time and expense? Apparently once we learn more about gravitational waves, we learn more about space and the universe around us—giving us insight into collapsed stars' matter and black holes.

Unfortunately we've got to cool our heals until 2020 before the Laser Interferometer Space Antenna (or LISA as it's known) is able to proceed and unlocks the last piece of Einstein's puzzle.
