Formula for schwarzschild radius
WebMar 29, 2016 · It is a coincidental consequence of the way the Schwarzschild radial coordinate is defined. There is no physical insight to be gained from attempting to derive the Schwarzschild radius this way. If we start with flat spacetime then the metric is: $$ ds^2 = -c^2dt^2 + dx^2 + dy^2 + dz^2 $$

WebUsing the expression for the Schwarzschild radius, the entropy of a black hole of event-horizon area A= R2can be written in terms of its mass using Eq. (1) as S= 4 k c G M2. As mass is lost, the change in entropy will be dS= 8 k c G mdm. Multiplying by both sides of Eq. (2) gives Tds= c2dm. Integrating from the greater initial mass Mto WebJan 15, 2024 · 1. The gravitational redshift in Schwarzschild relates the photon energy (frequency) measured by stationary observers at different radial coordinates. It refers to a free falling or free ascending light. The formula in the post assumes the farther observer to be at infinity (far away from the Schwarzschild radius).
