The main consequence of the Particular
Relativity Theory is shortening of moving objects.
It is quite clear ! The measurement
of the length is done by detecting the echo from the ray of light sent to the car. The ray reflected from
the front of the incoming car turns back quicker, and that reflected
from end of the car arrives later, and in the meantime this end is
closer. 1)
