i have wood -2 feet long: make a mark on the ground that is 0, then on each side make marks every foot, since our mathematical brains use common sense that to the left of 0 is negative, put the board to the left of the 0 marker! whoo... i am such ... an idiot
anyway time is a concept of man, therefor i believe it has no real connections to the universe and all that, and cant be travelled in, as a concept of man we stupidly follow what has been said for many years and believe there is actually time... HAH! ... so much stupider...
