WebMar 24, 2024 · In Section 2.2, we define the Euclidean FLRW metric by g μ ν = diag ( − 1, a 2, a 2, a 2) where a = a ( t) is the scale factor. At the end of the subsection, the book has the following passage. One final comment about the relation between energy and momentum for a massless particle as expressed in Eq. (2.29). If we define p i = a P i, 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. Webmetric and t = 0 in the Friedmann-Lemaˆıtre-Robertson-Walker (FLWR) metric, but it was thought that this was a consequence of the excessive symmetry of the solutions, as it occurs in many situations in classical mechanics or electromagnetism.

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. 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
