1. Firstly, we examine the properties of circular orbits and find that circular orbits could disappear when the deformation is large enough. This video is the first part of a three-part series that looks at how the form of the Schwarzschild metric is determined using symmetry arguments. (2021); Lobo et al. Orienting the coordinates so that the orbital plane of the photon is equatorial and defining results in d 2 u d ϕ 2 − 3 G M c 2 u 2 + u = 0 {\displaystyle {\frac {d^ {2}u} {d\phi ^ {2}}}-3 {\frac {GM The Schwarzschild metric tensor is both fundamental and useful, as it describes the curved spacetime around a black hole singularity, and is a good approximation to spacetime in the vicinity of gravitating bodies such as the Sun and the Earth. , the radial coordinate at which photons orbit M. Remember that the Schwarzschild metric is the unique metric around stationary, spherically symmetric, uncharged objects, so what these geodesics do is tell us how thing move around the Earth, around the Sun, and around uncharged, non-spinning black holes. It was found by Karl Schwarzschild and independently of him by Johannes Droste in 1916. A quick calculation in Maxima demonstrates that it is an exact solution for all r, i. In other words, r=0 is a bonafide singularity in the metric. with constant are parallel to one of the lines . Both t and tff are “far away time” in the sense that they tick at the rate you’d actually see time flow on a far-away clock at r ≈ ∞ if you had a good enough telescope to see it. The Schwarzschild metric goes beyond a theoretical exercise; it is a vital tool in modern science, facilitating advances in astrophysics, cosmology, and practical technologies. It's easier in situations that exhibit symmetries. 1916: Karl Schwarzschild sought the metric describing the static, spherically symmetric spacetime surrounding a spherically symmetric mass distribution. 3 Classification of surfaces with the symmetry of Schwarzschild metric ion in order to find various embeddings of the Schwarzschild metric. It is interesting to note that the result is a static metric. It is an exact vacuum solution to General relativity/Einstein equations, and according to the Birkoff theorem, all spherically symmetric exact vacuum solutions are equivalent to this solution, related through mere frame transformation. e. The Schwarzschild metric represents a spherically s mmetric solution of the Einstein equations in t dr2 ds2 = 1 − We would like to show you a description here but the site won’t allow us. In simple terms, the Schwarzschild Metric provides a mathematical description of the curvature of spacetime caused by a massive object, such as a star or a planet. Mar 5, 2022 · (This is generalized in section 7. In Einstein 's theory of general relativity, the interior Schwarzschild metric (also interior Schwarzschild solution or Schwarzschild fluid solution) is an exact solution for the gravitational field in the interior of a non-rotating spherical body which consists of an incompressible fluid (implying that density is constant throughout the body The only difference between the two forms of the Schwarzschild metric is the choice of time coordinate. Jul 13, 2025 · In Schwarzschild coordinates, the Schwarzschild solution is. Yet, analogy with Newtonian gravity and electrodynamics suggests that a more constructive way towards the Nov 3, 2019 · After introducing the metric as a tool to measure space-time geometry in our previous post, here we focus on the metric of a Black Hole (BH). , the Ricci tensor vanishes everywhere, even at r < 2m, which is outside the radius of convergence of the geometric series. The most obvious spherically symmetric problem is that of a point mass. Apr 1, 2014 · We review the standard textbook derivation, Schwarzschild's original 1916 derivation, and a derivation using the Landau-Lifshitz formulation of the Einstein field equations. In this fi Schwarzschild metric in General Relativity In this worksheet the Schwarzschild metric is used to generate the components of different tensors used in general relativity. The line element is given by: $$ ds^2 = The exterior solution for such a black hole is known as the Schwarzschild solution (or Schwarzschild metric), and is an exact unique solution to the Einstein field equations of general relativity for the general static isotropic metric (i. To summarize, we have found that the metric of a vacuum spherically symmetric spacetime must take the Schwarzschild form (up to coordinate rede nitions of ocurse). Expressing the metric in this form shows clearly that radial null geodesics i. The standard way to derive it is to employ Einstein’s field equations. 1 Derivation of the Schwarzschild Metric We want to derive a spherical symmetric metric. ) In particular, the Schwarzschild metric’s components are independent of ϕ as well as t, so we have a second conserved quantity p ϕ, which is interpreted as angular momentum.
