1 - The speed of propagation of gravity is finite.
2 - The speed of light is constant (in vacuum).
3 - Time is relative.
4 - The speed of light is the maximum value. (So far registered).
5 - The energy and mass are equivalent.
6 - All reference frames are equally valid.
I don't agree with (WEAKNESSES) :
1 - The curvature of space-time.
2 - Gravity is not a force.
Light curve is the result of gravity, and not by the space-time. Space-time is a mathematical model to place objects and events in the reality. Space and time are related, but not mixed.
