Hello everyone,
Reminder: The key of the explanation of the "twin paradox" resides in the acceleration. We know that the time runs slower for the twin in the spaceship (since it was accelerated).
---------------------------------------------------------------------------------------------------
Now I would like to share with you a thought experiment.
Let's imagine that we have triplets on Earth. Now we put two of the them into the spaceship and send them away with speed V1 relative to Earth. After some time one of the spaceship-triplets is send back to Earth in the space-capsule (in the opposite direction with the speed -V2 relative to Earth).
Let's take |V1| > |V2| in the Earth's frame. This means that in the Earth-triplet perspective the time dilation rate of the spaceship is higher than for the returning space-capsule.
Now let's look into this from the perspective of the spaceship. In this frame it was actually the capsule which was accelerated; so time must run slower in the capsule from the spaceships perspective.
So who is right? Time runs slower in the spaceship or in the capsule?
