Now if the scientific community came along and said dark energy was a force, and said it has more in common with gravity that the other forces, that would sit right with me. It would be like those 2 ...

Time for a physics lesson. We only feel gravity’s effect on us when we fall but gravity is always working on us- pulling us down at a force equal to our mass times a constant of 32 feet per second ...
