Hm. It's all getting a bit complex for me, having zero physics background yet and barely even remembering trigonometry at the moment. And then I get obsessed with perceived paradoxes and misunderstood concepts that are difficult to resolve when I don't have the necessary foundations and it...

sylas: Also, if, when the ship leaves Earth the alien star suddenly appears closer and bigger, wouldn't the Earth similarly appear bigger and closer when departing the alien star, instead of smaller and farther? I don't really understand why there's any size or distant shift of that sort at...

Re. 1 and 2: Ah, I was misinterpreting your (correct) definition of size. Got it. Re. 3 But now...returning to the format of the standard twin paradox...and if I take what you say to be correct: *On the first leg of the trip, the ship twin experiences the trip to take x amount of time (I'm not...

No, ryuunoseika, I'm new at this but I know that's not correct.

PS...when I say "she goes back"in #5, I mean "she is in"...to prevent any confusion there. She does not return to her other twin spatially, it's just that she's now in the same inertial reference frame.

Actually, maybe I know the answer to that last question...since the time at the "turnaround point" is perceived by the ship twin as being ahead of the un-synchronized home-bound-twin's time, then maybe the line of simultaneity between the "turnaround point" and the home twin is such that the...

Thank you so much, Sylas! I was already starting to get it with Minkowski diagrams, but you helped alot. It makes a lot of sense, particularly, on a basic level, the part about determining whether or not you were the one that switched frames. A few questions: "From the point of view of...

But from Clock C's perspective, where Clock C is stationary, isn't the A/B frame seen to be the one accelerating? Actually, that's confusing for me in the twins paradox as well...doesn't the ship twin see the origin planet decelerate, switch frames, and accelerate? Aghhhhh.

My apologies if this should be in the homework section, but it's more just a basic conceptual wall I've come up against as I think independently (with little math---just trying to get a very basic conceptual grasp of relativity). That said: Say there is a Clock A at Point A and a Clock B at...
