Le paradoxe des jumeaux

The twin paradox is one of the most beautiful paradoxes in physics. It stems from Einstein's special relativity, also known as special relativity. The twin paradox isn't that complicated to understand, even with just a few simple equations. Just enough to spice things up.

ADDITION FOR THE ASTOUND INTERNET USER TO READ AFTER WATCHING THE VIDEO The astute internet user will have noticed a paradox within the paradox. According to the twin on Earth, it's the twin in the rocket who is moving away, and according to the twin in the rocket, it's the twin on Earth who is moving away. This is the principle of relativity of frames of reference; there is no absolute frame of reference. How do we know which twin should be younger? It's the twin in the rocket, because he makes a U-turn when he arrives at Proxima Centauri. It's this U-turn that changes his frame of reference and throws everything into disarray. At the moment of the U-turn, the twin in the rocket falls behind the twin on Earth. A detailed analysis of the U-turn would have complicated the video. Perhaps we'll talk about it another time...
