abstract
General relativity can be presented in terms of other geometries besides Riemannian. In particular, teleparallel geometry (i.e., curvature vanishes) has some advantages, especially concerning energy-momentum localization and its ``translational gauge theory'' nature. The standard version is metric compatible, with torsion representing the gravitational ``force''. However there are many other possibilities. Here we focus on an interesting alternate extreme: curvature and torsion vanish but the nonmetricity $\nabla g$ does not---it carries the ``gravitational force''. This {\it symmetric teleparallel} representation of general relativity covariantizes (and hence legitimizes) the usual coordinate calculations. The associated energy-momentum density is essentially the Einstein pseudotensor, but in this novel geometric representation it is a true tensor.

Background-inert modified-gravity couplings create a σ80–λ degeneracy under compressed CMB priors, inflating σ80 and producing spurious model preference, which an implied-A_s diagnostic exposes.
A residue-based approach in f(Q) gravity claims that thermodynamic Hessian degeneracy in the extended state space produces corresponding shifts in quasinormal-mode frequencies, Lyapunov exponents, damping times, and near-horizon monodromy.
In symmetric teleparallel f(Q) gravity with nonminimal EM-nonmetricity coupling, the distance duality relation is dynamically violated, yielding a generalized formula relating observational distances to the Hubble rate.
f(Q) gravity yields Taub-de Sitter-like plane symmetric vacuum solutions, and quadratic models support isotropic slabs where maximum pressure is offset from the center with thickness and pressure increasing for negative α.
The scalar-tensor representation of f(Q) gravity reproduces the known ghost/strong-coupling obstruction, so the pathology is not an artifact of the original variables.
A single f(Q, L_m) gravity model with HRDE produces Starobinsky-like inflation at high curvature and late-time acceleration, with RGUP corrections keeping n_s and r consistent with Planck while shifting the running of the spectral index.
Derives background solutions for linear f(Q,T)=αQ+βT plus DBI field and reports MCMC posteriors from Hubble, BAO, and SNIa data that are consistent with late-time constraints.
Applies f(Q) gravity with linear nonmetricity and Krori-Barua metric to four pulsars, finding positive anisotropy, compactness inside Buchdahl limit, and Chi-square agreement for model masses across 30 values of parameter a.
