I thought I understood it as well but it seems a little more confusing than I thought originally especially because of this response by DaleSpam:
So, if I understand this correctly, it's the frame that isn't accelerating - any objects within it can accelerate at will. This may have been...
So, if I understand you correctly, an Inertial Reference Frame means that the object remains in inertia throughout the problem? I think I misunderstood that part. I thought that it had start in inertia - but I honestly, now that I think about it I don't know why I thought that.
Are you referring to the Equivalence Principle Analysis? I don't see how that entirely applies to scenario 2.
And, even with regards to the traditional straight line Twins Paradox, I didn't entirely understand why "Stella is far 'down' in the potential well; Terence higher up" in the...
You are right of course - I should have started with the straight line case. And, FYI, I did go through the FAQ you suggested. And, although it didn't directly address the issues I raised, it was informative.
Well, I put Alan and Bob in orbit, but what if you put them in a straight line at a constant velocity - it would work as an IRF and my setup would still work.
I am deliberately trying to bring up the multiple frames of reference. I understand the concepts behind single frame of reference (independent of the two twins) but I want to know how it would affect the scenario if I treated the accelerating twin as the frame of reference (I realize that it is...
Before people start bashing me for not reading up on other threads, I did try and perhaps I am not physics-savvy enough to understand but I just found the answers to be contradictory and confusing.
So, here are two scenarios that confuse me:
Scenario 1: Two twins start off on earth. One...
