Right now it's space x matter x time = X and was having a problem with time. Space has three directions, matter has three dimensions, and time has three aspects, (future, present, and past). Now if I can come up with the three aspects of causality I can continue.
The past and the future don't exist. Only the present.
But what is contiguous to the effect in the same way that the present is contiguous to the past? Looking for the third aspect of causality. Any suggestions?
