Can anybody explain me those contradictions.
1.If gravitation has speed = c and spread in form of gravitation wave. How it can escape Schwarzschild radius in black hole?
2. Magnetic field for black hole - how it can be possible? What create magnetic field?
3. Electrically charged black hole - the same as first one - How electrical field can escape?
4. Rotating black hole. Formula for time:
The equation is:
t_0 = t_f \sqrt{1 - \frac{2GM}{rc^2}} = t_f \sqrt{1 - \frac{r_0}{r}} , where
t_0 is the proper time between events A and B for a slow-ticking observer within the gravitational field,
t_f is the coordinate time between events A and B for a fast-ticking observer at an arbitrarily large distance from the massive object (this assumes the fast-ticking observer is using Schwarzschild coordinates, a coordinate system where a clock at infinite distance from the massive sphere would tick at one second per second of coordinate time, while closer clocks would tick at less than that rate),
G is the gravitational constant,
M is the mass of the object creating the gravitational field,
r is the radial coordinate of the observer (which is analogous to the classical distance from the center of the object, but is actually a Schwarzschild coordinate),
c is the speed of light, and
r_0 = 2GM/c^2 is the Schwarzschild radius of M.
What speed random point on Schwarzschild radius should have for observer outside of black hole to see any movement of it?
