Kerr Black Holes

The Schwarzschild reference frame is static outside the Black Hole, so even though space is curved, and time is slowed down close to the Black Hole, it is much like the absolute space of Newton. But we will need a generalized reference frame in the case of rotating Black Holes. Roy Kerr generalized the Schwarzschild geometry to include rotating stars, and especially rotating Black Holes. Most stars are rotating, so it is natural to expect newly formed Black Holes to process significant rotation too.

Euclidean Relativity’s Take On Space And Time

You know how space time are intermingled? Euclidean relativity is another theory which explain our current perceptions regarding space and time. It is just a transformation of minkowskian invariant….below is space time metric in Minkowskian invariant
