I merged some theory of relativity type stuff with people themselves as the subject.

A way of changing the context towards people and their relativity more than the absolute original concept

1- "all frames [or people] related to one another by such a transformation are inertial..."

2- "Newtonian mechanics added to the special principle several other concepts, including laws of motion, gravitation" [to each other or around each other]

[Newtonian relativity in this people way with the physics gravitation towards each other]

ADDED COMMENTS:

TIME IS ALSO A MAN-MADE COMPARTMENTALISED THING FOR PLANNED MATRICES

The whole idea that we 'lose' perception of time around good people or while we are doing good things (so time might be compartmentalised more due to inventions everywhere as a man-made matrix design then us always wanting to know the time
... i.e from 8am-5pm I must work and from 9pm-7am I sleep etc
In older days many things were synchronised by people and when they feel for it, when the arrive or to cut the long grass whenever!
