Electromagnetism is a very special case! In fact Einstein conceived Special Relativity starting from it (in his pioneer work "Zur Elektrodynamik bewegter Körper", "on the electrodynamics among bodies").
He also said that Special Relativity was already contained in Maxwell equations, for which...
You are trying to unify Special Relativity with Newtonian gravitation, I guess.
At the moment I have no idea about how doing that, but on one point I am quite sure. Newton's gravity has as framework the Euclidean space and three-vectors, while Special Relativity resides in the space-time...
No, there is no transition. The event horizon is not a real singularity, in fact it does not exist in Kruskal coordinates (I think). But a far-away observer sees the event horizon actually as a barrier (this is due to his reference frame).
So we actually see still forming black holes...
Hello! Can anyone help me with the following question about black holes?
Let us consider a massive star which at the end of its evolution collapses into a black hole (say a Schwarzschild black hole, for the sake of simplicity). An observer far away, in its coordinate time, will never see the...
Standard cosmology is based on the Robertson-Walker metric, which stems from the cosmological principle and is not rotating because of the homogeneity and isotropy. The cosmological principle seems to be true only on very large scales (over than 200 Mpc). So in this framework rotations are not...
Hello! This is a very interesting question! I remember that during my cosmology course I wondered if the Hubble flow could be alternatively explained by a rotating Universe theory based on some sort of centrifugal force! That would be amazing! However, a centrifugal force implies a centre, and...
