WHAT IS THE SHAPE OF SPACE?We’re used to thinking of space as the emptiness in which things happen, like an empty warehouseready to be filled, or a theater stage on which the events of the Universe play out.But General Relativity predicts that space is not just emptiness, it’s a physical,dynamic thing, and that prediction has been borne out by many, many experiments.Space can bend because of matter and energy, curving the paths of objects that move insideof it.It can ripple with gravitational waves And it can expand, creating more and more spacebetween two objects.All of these phenomena can be described by one idea: curvature of space (or spacetime).In flat regions of spacetime (like, if there’s no energy or matter nearby), objects travelingalong parallel paths stay ...
