Postulates

There is no such thing as ‘dark matter’.

A big mystery in modern physics: why do galaxies rotate as if there must be more matter than we actually see? Why is the universe said to expand faster than it should given the matter (stars and galaxies) we can observe? This ‘phantom’ unknown source of gravity is called ‘dark matter’.

Black holes

Why does gravity escape a black hole? Generally it does not, but.

This would be the classical view: Because this is a static property of space-time. It is called energy-density. So fields can not be faster than light, but gravity can? Yes, this is how Einstein calculated as well.
