I am trying to model a star using the old shooting method technique. I've encountered problems after my very first pass of integration. I know that I need to use a multi-dimensional Newton-Raphson technique and i think that I've not done this correctly. Could anybody please try and explain...
I am trying to write some code to produce a model of a star. I've done loads of research and come to the conclusion that for ease i want to represent the opacity in my model with the power law.
k=k(0)*(rho^alpha)*(T^beta)
this seems very straight forward apart from the fact that in every...
A tachyon can travel faster than the speed of light where the E-L equation of motion for a spacetime metric is equal to -1 (I think).
In a nuclear reactor you see Cherenkov radiation as a result of the emitted particle traveling faster than the speed of light in the medium.
Gravity well is a phrase coined by some jumped up hippy in the science fiction world.
A black hole is a consequence of the Schwarzschild metric. In GR the Schwarzschild metric is a solution to the Einstein equation. Where R=2GM a black hole occurs. It has this name as one cannot observe...
