It is said that there is neither an absolute stationary coordinate system nor a global inertial frame.
So where do inertial frames come from in the first place?
After accelerating at 1G (9.8m/s²) inside the spacecraft, what is the speed after one year and the speed of the spacecraft as seen from the starting point earth?

1. If one of the twin brothers rides on a rocket, makes a U-turn while moving at sub-light speed, and returns to meet again, the time progress of the one who moved by rocket will be delayed. 2....

ChatGPT Yes, indeed from a mechanics point of view, you don't need a Lorentz transformation (LT) if you have a relative rate transformation. A relative rate transformation is a transformation that...
