I had this alien physics revelation last night that all planets, stars galaxies, etc have net kinetic energy of motion inherent in their existence. Space is incapable of having any metrics for these objects in space or for their potential kinetic force in collision. Collision of objects with kinetic energy of motion , like water above a dam, is something that only is realized and indicated/ measured by an actual interaction with other massive objects, So we can calculate ... the speed of the earth by crashing an asteroid into the earth and finding out out much energy is released to determine that kinetic energy of motion of both objects . We can see our frames of reference speed of the asteroid coming in and record that and then figure out the total number of meters per second the earth is traveling in the cosmos , of the sun for that mater too. traveling in empty space that is.. So then I go an inventory all the massive objects in the universe and they all have kinetic energy ...
