And if one were to come up such a fictional force to explain length contraction, one would be completely and utterly contradicted by observations. You see, you and I and everyone on Earth are right now moving at a large fraction of the speed of light with respect to a number of reference points. Do you feel squashed? Which reference point would you feel squashed with respect to? The one to the West of us? Or the one to the North of us? How can we be squashed along two different axes at the same time? Do we shrink?? The Newtonian model can not - and does not - explain observed phenomena resulting from relative velocities approaching the speed of light. Now that we can observe such things in detail, the Newtonian model must be replaced, because it is actually wrong on many things. Full stop. I'm sorry to say, you are demonstrating a lack of knowledge of 20th century physics. If there were any question whether your papers on physics were in error, that doubt has been erased.
