Einstein's field equations explained
In the general theory of relativity, the Einstein field equations (EFE; also known as Einstein's equations) relate the geometry of spacetime to the distribution of matter within it. The equations were published by Einstein in 1915 in the form of a tensor equation which related the local spacetime curvature … See more The Einstein field equations (EFE) may be written in the form: $${\displaystyle G_{\mu \nu }+\Lambda g_{\mu \nu }=\kappa T_{\mu \nu }}$$ where $${\displaystyle G_{\mu \nu }}$$ is the See more If the energy–momentum tensor Tμν is zero in the region under consideration, then the field equations are also referred to as the vacuum field equations. By setting Tμν = 0 in the trace-reversed field equations, the vacuum equations can be written as See more The nonlinearity of the EFE makes finding exact solutions difficult. One way of solving the field equations is to make an approximation, namely, that far from the source(s) of gravitating matter, the gravitational field is very weak and the spacetime approximates … See more In the Einstein field equations • any desired steady state solution described by this equation is unstable, and • observations by Edwin Hubble showed that our universe is expanding. Einstein then … See more If the energy–momentum tensor Tμν is that of an electromagnetic field in free space, i.e. if the electromagnetic stress–energy tensor See more The solutions of the Einstein field equations are metrics of spacetime. These metrics describe the structure of the spacetime including … See more Despite the EFE as written containing the inverse of the metric tensor, they can be arranged in a form that contains the metric tensor in polynomial form and without its inverse. First, the determinant of the metric in 4 dimensions can be written Substituting this … See more
