The straight lines, but they're backwards - they should be small on the left, large on the rigth (i.e. we grow in knowledge with increasing truth) 

 You think time moves from left to right only? Just curious where this comes from. 

 Ah...I do indeed support the concept of non-linear time. (Physics is a hobby 😉 ) 

 Looking at it again, I think I'd answer number 2, My smooth brain didn't realize they're all the same just different view point.
