WebMay 10, 2024 · We consider flat FLWR metric (6) d s 2 = d t 2 − a 2 d x 2 Einstein equations are written in the form (7) R μ ν − 1 2 g μ ν R = 8 π G T t o t μ ν, where G is the Newton constant. The Friedman equation in the FRLW flat metric has the form (8) H 2 = 8 π G 3 (ρ + ρ d e). 3. Expansion around the homogeneous solution Weba flat FLWR metric indicates that the obtained solution can mainly describe the evolution of the late Univesre, it may also fit an early Universe. Hopefully, the present method when applied to the case with a more general FLRW metric can describe more precisely different stages of the evolution of the Universe. 1 Introduction

The FLRW metric starts with the assumption of homogeneity and isotropy of space. It also assumes that the spatial component of the metric can be time-dependent. The generic metric which meets these conditions is $${\displaystyle -c^{2}\mathrm {d} \tau ^{2}=-c^{2}\mathrm {d} … See more The Friedmann–Lemaître–Robertson–Walker metric is a metric based on the exact solution of Einstein's field equations of general relativity; it describes a homogeneous See more The Soviet mathematician Alexander Friedmann first derived the main results of the FLRW model in 1922 and 1924.

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. my time at portia ps5WebFLWR is an overdrive, distortion and sometimes fuzz!
