The field of cosmology and general relativity is vast and intricate, with numerous potential areas for misconceptions and errors. Initial mistakes in tensor calculations are some common mistakes ?
Unlikely because of so many people reviewing models. The mistakes (inconsistency with observations) are in the postulates (assumptions).
THE number one mistake is to add parameters or dimensions which is the opposite of the primary goal of simpler explanations. For example, current theories hole 4 different forces. The goal is 1 force directing matter/bodies for both cosmology and the small (QM or to explain the double slit experiment with photons).
The STOE does this.
Tensor calculations form the backbone of general relativity, as they describe how matter and energy influence the curvature of spacetime.
One of the common issues in tensor calculations is ensuring the proper handling of indices (both covariant and contravariant). Errors can arise from incorrect summation conventions or from misapplying the metric tensor to raise or lower indices. Another area where mistakes frequently occur is in the calculation of the Ricci curvature tensor and the Einstein field equations, which require careful application of differential geometry principles.
