Hi, I am doing my thesis on quantum entanglement and I don't seem to wrap my head around what really happens to an entangled system during a local measurement. I happen to know that information can't travel faster than light I could believe that the collapse of the wave function wouldn't allow...

I think that the error is in considering the Earth a rotating frame when it's just an accelerated one (due to sun attraction). If we choose the reference frame of Earth there is no Coriolis force caused by our rotation around the sun, at most a fictitious force balanced by the attraction of the...

Yeah sorry, I haven't chosen the tag quite accurately, maybe it's too simple for undergraduate. Actually I haven't done any kind of study on the subject yet, but I'm trying to. The question was only my own curiosity. If I'm too confused what kind of path would you suggest me to understand?

As far as I know, we can describe the universe as if every bodies uses to follow a straight path in a curved space-time. What kind of role does the electromagnetic field play in all of this? Can we associate a "space-like" field curved by the charge of the particle with it? Does the...

Yeah, that what I meant.

That's the point. Is there a reason for this behaviour? Why do two different objects accelerate the same with gravity? Is there a fundamental reason (coming from some kind of theory) or is that to be taken as granted from observation?

Thanks for the answer.

I've read about the equivalence between inertial mass and gravitational mass. But i can't undestand why is gravity more special then other kinds of force. I mean, why isn't charge equivalent to inertial mass? After all charge plays the same kind of role of gravitational mass in another context.
