Gravity is a weak force, and is attraction mode. the speed of the mass, is an intesely strong force. The doistance filled with dark energy/mattaer does nothing to slow down the ac celeration. therefore in the absence of a strong force, the force applied is immensely inneffective., until proximity, (distance) is in a small number. This only occurs in natural disasters. (collisins, devastating near misses of massive objects etc. Even black holes can be defeated by distance, mass, speeed, and time, Without this fact being true, material space would collapse onto itself ina pinpoint of massive pont of material energy. After matter reachs a cerain mass, it's gravity and densit turns matter to energy and the energy is actrted upon by gravity due to strong gravitational proximity. The strength of gravity increses with nearness.
