Going back to the twins example i,ll change that to the 2 special accurate clocks test.
If one was on earth , the other orbiting earth , they will read differently . Why? .
all i can at the moment think is gravity warps spacetime, can this be briefly explained in laymans terms ?
I really should go to bed ,
i shouldn,t of said in OP 'as sad as it seems' sorry guys bad comment !
