| Jan 13, 2020 at 14:24 | comment | added | ralfcis | I realize I made a mistake using the word "reciprocal". Using my math, Alice and Bob's perspectives of each others proper time is agreed to by both so it's the opposite of reciprocal. Now we know by the formula (ct')^2=(ct)^2-x^2 that all other perspectives of velocities from the origin share the same proper times as Bob. But will they also share the same proper time relationship to Alice as she shares with Bob? I'm going to need to investigate this when I have time. | |

| Jan 13, 2020 at 1:23 | comment | added | ralfcis | Ok I have a fix for this. I will write my questions on my other forum first instead of vice versa. This will give the question time to percolate before I put it here. Oh while you're here, could you upvote the question as well? Just kidding. | |
| Jan 13, 2020 at 1:16 | comment | added | Dale | When you know how to write a good question and don’t do it (as is the case with you) then it seems that you want your questions to be closed. Since that seems to be the case now I will let you know in advance that this is the last question of yours that I will ever vote to reopen. I think this is the third or fourth, and I tire of the drama | |
| Jan 13, 2020 at 0:56 | comment | added | ralfcis | I don't possess the terms I need to communicate clearly so I over-compensate with too much explanation. Old people tend to babble. My friend even told me, before she called it quits, no one needs to hear your life story ordering a coffee. And then there was the time . . . | |
| Jan 13, 2020 at 0:49 | comment | added | Dale | @ralfcis that it why it is important to write a question well the first time! You have been at this long enough to know what is expected. I have advised you on clarity and focus multiple times, and you have shown multiple times that you can do it. Just do it right first and let’s skip the perpetual drama | |

| Jan 12, 2020 at 23:40 | comment | added | sammy gerbil | Good. That looks much clearer. But please note that when a diagram is crucial to understanding your question, you should upload it here rather than provide a link to it. | |
| Jan 12, 2020 at 23:27 | comment | added | ralfcis | I've clarified and focused my question but it won't matter because I've never had a question reopened once it's closed. | |
