Derivation of schwarzschild radius
Webdiscovered by Schwarzschild, which describes spherically symmetric vacuum spacetimes. Since we are in vacuum, Einstein's equations become R= 0. Of course, if we have a proposed solution to a set of differential equations such as this, it would suffice to plug in the proposed solution in order to verify it; we would like WebMar 28, 2016 · It is a coincidental consequence of the way the Schwarzschild radial coordinate is defined.
