With relativistic time, there is a possibility of time dilation. But in Newtonian Model, there is no such time dilation. Do you imply that the Nature has only four types of forces and no new types of forces can be discovered ? So a new type of force can be associated with the dark energy. So, Newtonian Model(NM) is not 100% wrong. This implies some hidden forces in NM. So, length contraction is not optical. Its real and physical. Good. You agree to this point. If "compressive force" is confirmed experimentally; will you accept this or not?
