Einstein’s theory of relativity is really a theory of gravity. The idea is that gravity isn’t an invisible force that attracts objects to each other, rather gravity is warping space. And the more massive the object, the more it warps space around it.
Think of the sci-fi movie Interstellar where Cooper, Amelia, Doyle, and their weird-looking robot, went down to the water (Miller) planet. They left poor Romilly behind to care for the ship. Romilly knew that time moved very slow relative to Earth time. So slow, that one hour equaled 7 years on the planet. And we all know how that turned out when they couldn’t get their ship started after getting hit with a wave. Romilly was alone for a very very long time.
So now, scientists from the International Centre for Radio Astronomy Research (ICRAR) and the University of Western Australia (UWA) want to test the theory out after having set a world record for creating a stable laser that can penetrate the atmosphere.
Testing the Relativity Theory and Tele-Communications
Scientists can put a terminal on the ground and one is space and test Einstein’s relativity theory.
According to the lead author, Benjamin Dix-Matthews, the technique they use will eliminate atmospheric turbulence. “We can correct for atmospheric turbulence in 3-D, that is, left-right, up-down, and, critically, along the line of flight,” he said. “It’s as if the moving atmosphere has been removed and doesn’t exist. It allows us to send highly stable laser signals through the atmosphere while retaining the quality of the original signal.”
The other plus is the technology can increase the data rate from satellites to the ground much faster. This could mean a major breakthrough for telecommunications on Earth, as I imagine signals from satellites, the internet, and pretty much any other space-to-ground transmissions would be lightning fast.
