Why does the distance between two distant objects increase, which we know as the expansion of space? Answered:

Dark energy has no effect within the influence of gravity, and gravity will have no effect where dark energy dominates.

The effective mass of dark energy <0 causes anti-gravity.

Beyond the gravitational effect of any object, there is a tug-of-war between gravity and anti-gravity. 

The effective mass of dark energy is heavier than the combined mass of ordinary matter and effective mass of dark matter. So antigravity caused by dark energy overcomes gravity.

Therefore, galaxies move away, as if the space between galaxies is expanding.
