Did anyone carry out an experiment and observe that the contraction of space is only in the direction of movement?
For anyone reading this who isn't anti-science. This is how science works.
1) You start with a hypothesis, in this example we posit that a wave function will describe the behvior of light from the double slit experiment.
2) You set up the experiment, and the mathematical model. Then you calculate what results you would expect should your model be correct. You also calculate what results would disprove
your hypothesis (which is an important part of the experiment).
3) Then you run the experiment and verify the results. When you verify the result, and other people sonfirm the results, and no one rejects it then model is accepted as scientific.
4) Then scientists try to explain the result (which they understand because that is their expertise) to laypeople.
5) The Philosopers who don't belive in science and don't have any expertise (since they haven't taken the time to learn) read the scientists explanation.
So scientists continue doing science, and so-called "philsophers" keep rejecting it.
Of course, scientists do try to take the time to explain to these "philosophers" what they are getting wrong, but it generally doesn't work. I don't know who is more foolish in this interaction... the philsophers for being stubbornly ignorant, or the scientists for not just giving up and going on to doing more science.
Scientists (i.e. people with science degrees who accept science as taught in universities) are landing robots on mars and developing vaccines to end global pandemics. The philosophers, when they are not rejecting science, spend their time twiddling their thumbs about whether good is bad or bad is good.
