This is one thing that always got me. Isn’t this all based on movement? When we talk about time in warped spacetime being different from time “elsewhere” isn’t it usually based on how we track time? (physical clocks, atom vibration, etc…) An example I remember reading about was the light clock on a moving object. The faster you move the “longer” it takes the light to bounce from mirror to mirror, but that shouldn’t change what one bounce was initially defined as.

We defined time as a measurement between two points of “existence” to relate to changes within that period at what I’d call “standard spacetime.” I’ve always felt like one second is one second, it’s just your clock that was affected.

I guess it’s the relative part that gets me. If it’s all down to movement, down to the atom, everything that could happen in 1 earth second on earth happens in the ticking of 3 seconds in altered spacetime does it actually mean anything significant?

…idk now after writing it out I’m more confused about why I was confused. It makes sense, it just feels like it shouldn’t make sense lol
