Astronomy

when a thing is not in a position where it should be, it is dragged towards its most probable place. I THINK they call it gravity. god knows. energy is intangible how can it be dark or light. anyway i think scientists have gone at an extent right in their way as far as describing energy. its self is not seen and its effects r prof of its existence. i think its untagibility causes one to call it dark. please clear ur question if i have not got it.
