Predicted by Albert Einstein in 1916 as part of his general theory of relativity, these waves could help scientists solve many mysteries about the origin of the universe – if they could detect them. In an attempt to do this, researchers at Stanford University and NASA’s Goddard Space Flight Center are developing a new atomic interferometry technique that may be sensitive enough to record gravity waves for the first time.
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
