As suggested in post 6, Time, Space, Mass and Energy are properties of the world/decisive factors which shape the world endogenously, being generic and not independent, their proportions being fully interrelated, continuously changing each other’s proportions.

As suggested in post 29, gravity and the strong, weak and electromagnetic interactions are  bound endogenously by C=T/M x E/S.
For gravitational and strong interactions this means C=T+/M+ x E-/S- or C=T-/M- x E+/S+. For electromagnetic and weak interactions this means C=T+/M+ x E+/S+ or C=T-/M- x E-/S-.

The consequence of both suggestions is that any change of Time and/or Space and/or Mass and/or Energy  will have some effect on gravitational, strong, weak and electromagnetic interactions. This is a continuous process of changes in Time, Space, Mass and Energy and the ratios between them, continuously affecting results from the gravitational, strong, weak and electromagnetic interactions, causing Time, Space, Mass and Energy to change again etc. In general such changes are rather small, but in areas where they are (very) big, examples that spring to mind are Black Holes, their composite effects must be unmistakable.

Conclusion:
Gravitational , strong, weak and electromagnetic interactions are generic and not independent, their proportions being fully interrelated, continuously  changing each other’s proportions (see for instance post 12). This means that their effects are resultants, sharing the same agents Time, Space, Mass and Energy.

To be continued.
