You are right and I fully agree with you. I employed the
additional word 'most' as sort of safeguard to avoid
conceivable argumentation from people who 'believe' otherwise
that could give rise to inutile debates. BTW, I read a few
years ago that there was a project to send an apparatus to
the space to (once again) test the relativity theory. Does
anyone happen to know more of that?
