According to general relativity, people in different reference frames are experiencing the same spacetime reality but from different perspectives. This is because time and space are not separate entities but are part of a unified spacetime that can be experienced differently depending on one's relative motion and gravitational field. This is the basis for the concept of time dilation in general relativity, where time appears to slow down for objects in motion or under the influence of stronger gravitational fields, as observed from a different reference frame.
