Thank you Peter, I did say to Ibix earlier that I was giving up, as I clearly do not and cannot understand the concept of relativity. Also, I am clearly not expressing myself very well, but since you have been kind enough to try to help, I shall make this my final attempt, and if it makes you...

This will be my last epistle on this subject, as I am clearly unable to follow your logic. I can understand that different frames do not agree about what "at the same time" means, however, I was not suggesting any measuring being made across frames. In each case, the traveller had stepped back...

You have been most helpful again Ibix, actually I think I am running the experiment three times; the first part establishes the ratio of lapsing time for those involved, with one of them going from zero to 0.6. The second part involves a number of them, going from zero to 0.6, and third one...

Thanks again Ibix. Please let me sleep on this (in Australia, we sleep while everyone else is up and active). I think you have almost understood me, but I still am confused (don't worry, by the time I am finished, you will be tearing your hair out) by your reply, as indeed you are by mine. I...

Still struggling a bit here. But, if a large arm comes out of High-speed, and catches everyone required, especially Tim and Tom, and takes them onto High-speed. They will then be together on High-speed, in a fairly small space. Their watches should still be ticking at the same rate, and they...

OK,I am being thick here. Some time after Bob has found out that Bill has 'lost' a minute, the relevant population on 'Normal' are scooped up and land on 'High-speed'. Bill is no longer of any concern. Some time after this event, hours, days, weeks possibly, Tim and Tom perform their experiment...

Some time after Bill and Bob, and before Tim and Tom do their experiment. Is that important, and is that what I am failing to grasp? Thanks again.

Thanks Ibix. I replied to jbriggs444, explaining my real problem, so if you don't mind, could you please look there? If the real problem is just that I am dense and shall never understand relativity, I can accept it. But if you can point out the flaws in my logic, I shall be grateful. Thanks...

Thanks for that, however, I said that was the easy bit. Where I get a problem is as follows. Applying your logic to another situation: Bill and Bob live on a long, flat planet called 'Normal', adjacent to which is another long, flat planet called 'High-speed', passing Normal at 3c/5. They have...

I have always had an interest in relativity theory, though have struggled to wrap my head around it. But, now that I have retired, I thought I should try once again to understand its intricacies. Following the discussions in 'One Way Twin', initiated by Buckethead on 16th June last year, has...

Thank for replying. As you can see, I am struggling somewhat with this concept, and thanks for your assistance. I have had a short period of thinking about it, and your direction has helped a bit. I shall do some deeper thinking, and see if I can get it straight in my mind.

I am a new user of this site, and have not studied physics in forty years. However, I was reading Janus' Special Relativity Primer at http://www.thephysicsforum.com/special-general-relativity/25-special-relativity-primer.html , with its excellent animated diagrams, but am having considerable...
