Thank you (all) for your assistance on this issue. The purpose my current interest is that I'm writing an article for a few people that expressed interest in this, but they are much more "science challenged" than I am. I'm not trying to get a degree in astro-physics. I wrote something I called...

Thank you.

No offence, PeroK, but you seem to me to be ignoring my question. Let me try to be more precise. In the situation where person A observes person B moving at great velocity (from person A's perspective), person A needs to use the dilation equations to assess what they, person A, "sees" as the...

Every time I think I get it; I don't get it. Let me first see if I understand this now and, if I do, then I'll have another question. The time dilation equations attributed to Special Relativity are merely a phenomenon of the "at rest" observer of something moving at great velocity. They have...

Ah HA. Thank you.

I get that, but it is not my point. In your example, of course there's no differential, but, ah hah, when they return to Earth, they meet for the first time their long lost, forgotten, brother, who, as it happens is their triplet brother and now this triplet brother is older than the traveling...

(I'm beginning to think I should change my level from Intermediate to Basic). What I said, "The observer also measured his mass and length..." was badly worded, by "his" I meant his brother's (the observed twin) mass and length. And you said: No. The evidence is not of "time dilation". It's...

Okay, I get that. But, as I understand it, the twin that returns to his at rest, observer brother and IS now younger of the two twins. This is a real, tangible, lasting attribute (for the lack of a better word) of a person that traveled at high velocity to include near light speed. However, the...

Great! That's what I was looking for. Thank you for your time (and patience).

My name is Jeff. My interest is in the Cosmos. I received an AA in Physics (with Transfer) and then moved on to computer science. I spent 35 years in the computer science field. I've always been intrigued by the planets and the solar system. My interest was rekindled with the Carl Sagan's...

I get it that when traveling at relativistic speeds lengths and masses will dilate. Upon return, however, there is no longer any dilation. For time, the returnee is younger than his twin. Is there any such indication that the returned twin had experienced dilation of mass or length?

Thank you, but I'm not sure I understand what you're saying. I'm envisioning twins, identical weight, shape, etc. Both have a rule of the same weight and length. One stays home, the other goes on a trip at relativistic speeds and returns. I already know when the traveler twin returns home, he's...

We know that time dilation is "real" in the sense that a subject at relativistic speeds or gravitational changes are measurable even when the subject returns to an "at rest" state. But are there lasting effects with mass and distance dilation under the same circumstances?
