Thank you! This clarifies the equivalence principle. For some reason it encourages many people to equate the effect of gravity with the effect of acceleration.

Thank you! That's the explanation I was looking for. So what you are saying is this: If you have a rocket accelerating in empty space with ##a=g ##, then all the experiments inside the rocket will match the experiments on Earth (locally at least). A clock at the end of the rocket and one at...

My question is about comparing the time dilation of a clock on a spinning disk versus a clock in the vicinity of a massive object. It seems there should be a connection between the two, because of the equivalence principle, but I'm missing something because I don't quite get the answer I would...
