Later in the thread I amended the scenario so that the probe launches occur when the two ships measure an agreed upon distance between themselves after they pass. After seeing the spacetime diagram Ibix provided I understand it doesn't matter, if motion is regarded as relative the proper time...

Thanks, and the diagram with accompanying explanation of it you provided is really helpful. I've downloaded a screenshot of your comment for future reference. Edit: am I reading it wrong, or did you accidentally put the probe return at 11 instead of 12? Edit: nevermind it's my bad eyes!

Thanks pervect, I'll read up about relative simultaneity some more. I don't think the video was wrong I probably just misunderstood it. I'll have another go at trying to find it. It was depicting a minkowski diagram of the twin paradox and showed the traveling twin moving away on an angle then...

I'm not insisting on anything, this is just the scenario that popped in my head after learning of the odometer analogy. I get that, and I'm not trying to be obstinate or anything. Nor am I trying to say relativity is wrong, this is just what I thought about after the odometer thing.

I appreciate everyone trying to help me, I'm a bit overwhelmed as I'm twenty years removed from any algebra or geometry lessons and it was never my strength to begin with. Okay, if you'll permit to try and clarify through written explanation you may be able to help me find where I've taken a...

(Later! Not late lol.)Well once they sync their clocks, I'm assuming as long as the probes are launched at the same clock reading it would be a symmetrical launch. The wait is to allow linear motion through spacetime to accumulate on the probe clock before sending it to the other craft. Then the...

Sorry I tried to clarify in an edit but you started responding before I made it. So if the ships and probes all sync at the passing, from that moment I would expect there to be a linear component of "motion through spacetime" plus the arc trajectory for the clock to read. That's why I thought...

I'm trying to find it again, I must not have been logged in on YouTube because I'm not seeing it in my history. Hmm, I'm afraid I don't understand why "distance through spacetime" precludes the horizonal motion in my example. Or the linear component rather. I should also have been more clear...

Hey again physics forums! I'm just a lug who likes watching science videos and appreciates the occasional answer to questions that pop up as I watch them. This morning I came across a video that explained time dilation really well by using an odometer analogy, that a clock is like an odometer...

Yeah that makes sense. There's a lot to keep track of when you first learn about this stuff. Thanks for your time

Okay sorry one follow up question. If the ladder is 90ft and barn is 30ft long, the ladder frame sees the barn as contracted right? And the photon from the left door can't be sent until it closes. So wouldn't that result in only like the last 5ft of the ladder getting scorched, but perhaps more...

Ohh nevermind it's the right most door. I think I got it now

Hey thanks, just to be clear if the ladder is moving from left to right, the back door is the first door it encounters?

Thanks for moving my comment, sorry about that [Mentor replies “no problem, no apology needed”]

[mentors’ note: moved from another thread because it’s a different question] Preface: I'm an idiot who occasionally watches science videos and has questions. If it's not inappropriate to tag on to this post, as I too have questions regarding relative simultaneity and apparent contradictions...
