👉 In physics and related fields, "spacetime" refers to a three-dimensional space-time continuum that describes the motion of objects in an accelerated gravitational field. It is the framework through which scientists study phenomena such as gravity, time dilation, and relativity. The term "spacetime" can also be used to refer to the concept of a temporal dimension in the context of special relativity, where time is treated as a four-dimensional space-time continuum that is observed from a stationary reference frame.
