If time did not exist in some fashion, then change would be impossible. Remove time and everything is simultaneous or eternal. What we say was or will be exists

If time did not exist in some fashion, then change would be impossible. Remove time and everything is simultaneous or eternal. What we say was or will be exists along with all we say presently is. Naturally, this leads to a contradiction. Imagine something moving along a trajectory that was at position p1, is at position p2, and will be at position p3 is now in all three positions. Add another object on an intersecting trajectory. A collision occurs when two objects are at the same position at the same time. Without time, these objects are both colliding and not colliding.
- SiempreViernes 9y agoDraw two crossing lines: the lines are mostly not touching except at the point they cross, so they are both touching and not touching depending on where you look. Is this a contradiction?
- bobthechef 9y agoAt the POINT of intersection. Those objects are both at the point of collision and not at the point of collision.
- SiempreViernes 9y agoThe same is true for the crossing lines: they are both at the point of crossing and at all the other points along their length.
