- TL;DR Summary
- If the table (with the mirrors, beamsplitter, etc.) is rotated 90 degrees, one arm will get shorter (due to lengthcontraction) because its longitudinal speed goes from zero to 30 km/s (our speed around the sun) and the other arm will get longer as its speed goes from 30 km/s to zero. So with a total 'armlength' of 11 meter, the difference in lenghts of the lightpaths will be around 55 nanometer, to be messured as appr. 0,1 wavelength. They messured no differences more than 0,02 wavelength.
