- What is time dilation really? 8 answers
In many textbooks and online answers I have heard people go on about how time dilation accounts for the gap of time experienced between two observers. However, they continue that in reality this is not enough and we must have length contraction as well to truly close the gap.
From an intuitive perspective, can't time just slow down a lot and then this can cover the gap in time all by itself? Why must there also be length contraction to help cover the gap? Can't time just slow down more? I would really like to understand this on both the intuitive and mathematical level.
