In general relativity, time is baked into the fabric of the universe ?" our physical reality is set in space-time. Under this theory, time can warp and dilate in the presence of gravity. But quantum theory treats time as something that is not malleable and does not change like other properties of a quantum object ?" recording its passage requires an observer to consult a clock external to this object. General relativity and quantum theory describe objects at vastly different scales, such as stars and atoms, but because these all exist within the same universe, many physicists believe that the conception of time shoul
