Describe the twin paradox using your own name and a twin (your name backwards) to explain the paradox and why both of you cannot be the youngest if your lucky twin went exploring the Universe in a space rocket
If Yalee and Eelay are moving relative to each other,Yalee wit see Eelay's clock moving slower than her own clock and Eelay will see that Yalee's clock is moving slower than her own. This is because they are in a different frame of reference.
If Eelay was to go on a journey into space, Yalee will expect Eelay to be younger since she sees Eelay's clock moving slower. However, according to Yalee, she would think that Eelay is aging much more slower than she is since she sees that Eelay's clock is moving much more slower than her own.
BUT they cannot both be younger.
This is called TWIN PARADOX.
Who will be the youngest?
Eelay will appear younger since she is the one that is accelerating. General relativity shows that during acceleration, clocks tick slower than when you are at rest. Therefore, Eelay will appear to be younger.
What was developed to satisfy the twin paradox?
The Hafele-Keating experiment was developed.
