Special Relativity Part 3: Length Contraction

from Professor Dave Explains Hosted by Professor Dave Explains

Time dilation was pretty weird, huh? Well we aren't done yet! Time is relative, and so is space! Different observers measure different lengths for objects and journeys. It's called length contraction, and it's another important part of special relativity.
