I think you might have answered this question yourself:

Actually "the second has been defined as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom", we're no-longer using astronomical measurements. I just wanted to point that out, as it's way cooler.

Isn't that definition of a second based on change, given that is is the measurement of transition (aka change) of levels of the ground state of an atom? I think you've noted that change does indeed exist with just about the purest, indeed elemental, of examples.

Just a thought; I could be wrong about this...

I suppose you could look at it that way, that's fine really.

It's this bit that's too much for me

How so? Doesn't the transition of the ground state of an atom show real change, at a truly unequivocal level? If not, then what does it represent?
