A quantum origin for spacetime
Newton’s apparent force of attraction became an illusion perpetrated by spacetime geometry. But as a laboratory for studying theories of quantum gravity, it has a lot to offer. In a similar way, perhaps the four-dimensional geometry of spacetime could be encoded in the math of quantum physics operating in three-dimensions. In any case, investigations along these lines have revealed a surprising possibility: Spacetime itself may be generated by quantum physics, specifically by the baffling phenomenon known as quantum entanglement. Vigorous effort by several top-flight physicists has produced theoretical evidence that networks of entangled quantum states weave the spacetime fabric.
