It has always bothered me that although time dilation has been verified that length contraction remains elusive. Why is that?
If we consider the fact that in our local frame of reference we will always record the speed of light to be c in a vacuum. In other media we have the data available to correct for changes in light speed. So we should always be able to tell locally how far light has traveled and how long it took.

Why is that?Simply because its too difficult to directly measure changes in length of objects moving that fast.Quote from: jeffreyH If we consider the fact that in our local frame of reference we will always record the speed of light to be c in a vacuum.
