MeJennifer said:I would be interested to know how the author thinks that all observers agree on rest length in general relativity.
Is it the case, that in general relativity the rest length is not absolute?
How is the rest length defined?
Is it the problem, that it is not clear how one should choose the rest frame of some object, if the object is large?
