You can measure acceleration without needing a special frame. More significantly, you can measure rotational motion without something to measure against. See

You can measure acceleration without needing a special frame. More significantly, you can measure rotational motion without something to measure against.
See that Feynman quote I linked in my original post; he discusses exactly this point.

- shardling 13y agoBut the argument you used would seem to apply to both of those thing. That's what makes it flawed -- you claim it is obvious, when in fact this line of argument is very subtle and often misleads laymen. (Notice that in this very thread there seem to be people who think you couldn't detect acceleration.)
