Could an object, assuming possible, escape black hole by travelling above constant speed? [closed]
I am always hearing that after travelling inside a given BH's event horizon, the escape velocity is greater than c, which makes it impossible to escape.
Suppose an ship is inside a BH. Assume it is ...

Does matter accelerate to the speed of light as it approaches the singularity?
$$v_\mathrm e=\sqrt{\frac{2GM}r}$$
If we understand the escape velocity to be the speed needed to escape from the 'surface' of a gravitational object described by the above equation.
It is equally ...

Why are the high density regions in outer space black holes?
The escape velocity of an object is given by the following formula.
$$v_e=\sqrt{\frac{2GM}{r}}=\sqrt{\frac{2 \mu}{r}}= \sqrt{2gr}$$
As far as I am aware, the mass of the star which formed the black ...
