Twins Aged Differently: A Relativity Paradox Explained

[Al68]

Hello Al68.

But what you have described is not the twin paradox without acceleration. For the apparent paradox to be present they must be reunited.

Why does the twins reunion cause an apparent paradox? To anyone familiar with SR.

Also in your scenario they cannot have started life as twins and pass each other at the start as twins.

Yeah, you're right, I wondered when someone would notice that. Of course it doesn't really matter here.

I do understand what you are trying to do but twins are irrelevant in your scenario as you are only showing that an accumulated time difference appears without acceleration which we already knew. The lack of need of acceleration is removed by the twins never starting/passing as twins and not being reunited.

Well, for something we already knew, it sure seems controversial.

Thanks,
Al

Hello Al168

I said apparent paradox because it is not a real paradox. I have no problem with it. Others do have a problem. I see nothing controversial.
