ROTFLOL....You don't even understand what length contraction means in SR. In
SR the length contraction is not physical. It is an apparent geometric
effect. It is the geometric projection of the moving rod onto the observer's
frame. From the moving rod point of view the space in the direction of
motion is contracted but the physical length of the rod remains the same.
BTW your bogus premise of physical rod contraction has the following
problem:
1. Two identical rods A and B and B accelerated away and becomes initial
again.
2. A sees B is physically contracted during B journey.
3. B turns around and rejoins A. B's physical rod length returns to the same
length as A.
4. That means that during the return trip B's physical length is physically
expanded.
5. That means that we will have both physical length contraction and
expansion. Questions: How is B know when to physically contract and when to
physically expand??
