Mixing Time into Space: Not Physics!

Modern physics is based on Einstein's Special and General Theory of Relativity SR and GR based on concept of spacetime where time is mixed into space as expressed in particular by the Lorentz Transformation LT as the essence of SR. This makes modern physics counter-intuitive with surprising strange effects of time dilation, space contraction and relativistic mass.

Let us take a fresh look at the idea of mixing time into space and ask if it can be possible from physical point of view. Consider a physical world composed of physical bodies with the following characteristics:

1. A physical body has extension in space coming with positive mass. 
2. Extension in space is manifested as existence of the body as the collection of its parts at the same time, that is simultaneous spatial existence/configuration. 
3. It is not meaningful to consider spatial existence of an extended body without simultaneity.  
4. Change of spatial configuration of a body can be seen as a body clock measuring progression of object time in terms of spatial change.
5. Two objects can interact by spatial contact, which synchronises object clocks to read the same.
6. Spatial contact between the parts of a body establishes simultaneity over the body.
7. A physical world does not carry a coordinate system to monitor its changing state. Object configurations change by simultaneous contact, which is represented by changing object configurations without need of representation in human made coordinate systems.
8. A human made spatial coordinate system can be a 3d Euclidean coordinate system fixed to the Earth, Sun or distant galaxy. 
9. Simultaneity of contact respects causality between two objects in the sense that agreement of order in time is possible.  

Notice that SR breaks 2-3. Spatial existence in SR has no extension in space and does not include simultaneity, which means that causality as order in time cannot be secured. Physics without causality cannot work.

So far this is a mechanical world without gravitation, governed by contact. Gravitation can be added by introducing a gravitational potential which depends on simultaneous spatial existence of all the physical bodies of the world asking for complete object time synchronisation (OS). 

Is (OS) possible? How can two far away bodies synchronise time without contact? Is it possible that  the gravitational potential as a massless field carries a master clock and gives birth to object/mass configurations along with object clocks synchronized to the master clock? This connects to the need of "absolute time" in Newtonian mechanics. It represents a non-standard form of causality where the gravitational potential is primary and mass distribution secondary, or possibly have equal roles in a perfect harmony in the sense of Leibniz. 

The gravitational potential of the Universe would thus as extended field carry a simultaneity of presence like that of an extended material body, a simultaneity instantly transmitted to material bodies as gravitational force synchronising all object clocks.

We thus arrive at a material world connected by simultaneity carried by changing spatial configurations connected to a master gravitational potential. 

In any case there will be no mixing of space into time upsetting simultaneity. This is fundamentally the view of Leibniz.  

Summary: In world without gravitation simultaneity is established by spatial  contact, and serves no role without contact. In a world with gravitation, a master gravitational potential can establish global simultaneity, to be used in electromagnetics.
