a) There is only one kind of ''time'' and it is gravity-time.
We live on/in Earth gravity-time.
For us this gravity-time is absolute, but from cosmological view and GRT
this gravity-time is relative, because every planet has its own gravity-time.
b) All laws of physics are the same on every gravity- planet.
c) The opposite ''face'' of gravity -time is an eternal -infinite -absolute vacuum.
Every gravity- planet-time exists in this eternal vacuum continuum: T=0K.
The laws of physics are changed from gravity-reference frame to vacuum continuum
and vice versa. These two systems have different physical laws.
Until today the connections between these two system is unknown.
