It is true that Riemann space is incomplete and misleading.
There are many arguments to prove this dilemma, but here we focus on the fact put forward by Google and Wikipedia:
(No, the Riemann tensor cannot "solve" special relativity; it is a tool of general relativity used to describe the curvature of spacetime, which does not exist in the flat, uncurved spacetime of special relativity. The components of the Riemann tensor are all zero in flat spacetime.)
The above justification is laughable!
Imagine, just imagine, that a certain space is fabricated to solve a single problem.
However, the author believes that the Riemann tensor is a satanic trap.
One may wonder how the great Einstein fell into such a trap when proving his theory of general relativity, which thus proved to be incomplete and misleading.
