WebApr 8, 2024 · We present analytical solutions for two different relativistic generalizations of our recently introduced nonrelativistic cosmological model with dynamical curvature (NRCM). These relativistic... In general relativity, the metric tensor (in this context often abbreviated to simply the metric) is the fundamental object of study. It may loosely be thought of as a generalization of the gravitational potential of Newtonian gravitation. The metric captures all the geometric and causal structure of spacetime, being used to define notions such as time, distance, volume, curvature, angle, and separation of the future and the past.
WebAug 12, 2024 · FLRW metric invoked is just a framework whose consistency is being checked. From the location of multiple images of a strong lensing system, one is able to … Webequations or over background FLWR space-time with the metric: ds 2 F = dt 2 − a(t)δ ijdx idxj, (8) In what follows we assume for simplicity that the FLWR metric is spatially flat. Transition from this metric to conformal one (6) is given by the linear transformation between time components of the coordinates, dt= a(τ)dτ.
