Most evidence I have seen for the existence of ‘dark matter' can be interpreted as evidence that momentum is relative.

It has also been suggested that galaxies are ‘accelerating' when we would expect gravitational attraction to cause deceleration, and this, it has been suggested, indicates the existence of some kind of ‘dark energy' which possesses a repulsive force, and somehow has managed to elude even our most sensitive detectors.

Let's assume that space and energy are equivalent, and that therefore a three dimensional space field is just one more manifestation of that chameleon known as energy, and that a space field is an energy field. Now let's also assume that a black hole were to eat some mass or another. Would it also not be true that at the same time the black hole would also be eating the momentum field energy of that mass. Would not all this eating cause a black hole to gain momentum energy (‘dark energy' as its called) at the same time as that black hole was gaining mass. Would not the result be acceleration of that black hole and therefore continuous acceleration of the galaxy which is in the orbit of that blackhole?
