    Basically all of astronomy, we have no “why” for any of it.

    “Ah, we’ve deduced that about 27% of the universe is made of… Dark matter. Don’t ask. But more importantly…68% is made of dark energy. Also do not ask.”

      Also, gravity. It’s very well understood. Mass exerts gravitational force. Like other things, it moves at the speed of light, and works in waves.

      But why does mass exert gravity? NO FUCKING CLUE. Other forces work though electrical charge. But even antimatter exerts positive gravity.
