Gravity Unveiled In a four-dimensional Minkowski spacetime with the metric signature , the Minkowski metric tensor can describe the curvature of spacetime caused by a massive object.
Explanation: The Minkowski metric is the metric tensor of flat spacetime in special relativity and does not account for spacetime curvature caused by massive objects. Curved spacetime, as described in general relativity, requires a general metric , which incorporates the effects of the energy-momentum tensor via Einstein's field equations. The Minkowski metric is only valid in the absence of gravitational fields.
