Thank you for pointing that out. You are correct. The fact that one twin changes from one inertial frame to another is the important...

Yes, absolutely right. Inertia force of acceleration can be regarded as a gravitational force. Just like fictitious centrifugal and...

When the astronaut is moving at a constant speed, he is in an inertial frame, so he can consider himself to be at rest. But during his...

Fascinating! I like your generalization of Collatz. It is a perfect analogy of Collatz for different a values. I would like to point out...
