Is the curved spacetime of General Relativity possible to be described by Minkowskian space which is flat, or do one need some other geometry?

General Relativity is a theory developed by Albert Einstein in the early 20th century to explain the force of gravity. It proposes that gravity is not a force between masses, but rather a curvature of space and time caused by the presence of mass and energy.
Minkowski space is a mathematical model of space and time developed by Hermann Minkowski. It is a four-dimensional space where the three dimensions represent space and the fourth dimension represents time. This model forms the basis of Einstein's theory of General Relativity.
Unlike Newton's theory, General Relativity does not consider gravity as a force between objects. Instead, it describes gravity as a result of the curvature of space and time caused by the presence of mass and energy. This theory also accounts for the effects of gravity on the trajectory of light and the bending of space and time.
One of the most famous observations that support General Relativity is the bending of light near massive objects, such as stars. This was first observed during a solar eclipse in 1919. Other experiments, such as the Shapiro delay and the Pound-Rebka experiment, have also provided evidence for the theory.
Yes, General Relativity can be unified with other theories, such as quantum mechanics, to form a more comprehensive theory of physics. Many scientists are currently working on theories that attempt to unify General Relativity with quantum mechanics, such as string theory and loop quantum gravity.
