In other words, and contrary to popular simplifications, it says that what is true will be true for all observers. — Banno

The length of a moving rod? The time on a clock? The velocity of a moving body? These are all observables; they are not invariant. — Kenosha Kid
Observer A will see a rod of length l. Observer B will see a rod of length l'. But observer A will also see that observer B will see a rod of length l'; and observer B will see that observer A will see a rod of length l. They do not disagree as to the facts. — Banno
Yep. And A wold be wrong. — Banno
What they agree or disagree to is irrelevant. — Banno
What philosophy could learn from relativity is not to impose human psychological frameworks for understanding the world on the world itself, that the ways we think and what we think important are not objectively useful. It should learn that what is true for me is not necessarily true for you, that while there might be a direct map from my experience to yours, one is not necessarily true and the other false. — Kenosha Kid
For instance, I think that most physicists would probably reject moral objectivism, whereas most philosophers I've spoken to believe it is true, and I do think that relativity, while having nothing to do with morality, did impact how we think generally about objective frameworks. — Kenosha Kid
Crazy religious nuts object to relativity in physics because they think it will lead to moral relativism. Don’t give them any ammo. — Pfhorrest
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
