Ask Ethan: If Mass Curves Spacetime, How Does It Un-Curve Again?

Matter tells space how to curve, and curved space tells matter how to move. That’s the basic principle behind Einstein’s General Relativity, which linked, for the first time, the phenomenon of gravity with that of spacetime and relativity. Place a mass down anywhere in the Universe, and the space …
