Of course the math check out, they are correct, but in my opinion, time is not a dimension, it's the 'refresh rate' of matter.

To me, there are only 3 dimensions, that of space.

That does not mean the relativity math is useless. On the contrary, what they describe is real and we can experimentally verify it.

But that does not mean we can 'move' into time, as we 'move' into space. That's why time is not a dimension.

I don't believe refresh rate captures the transmission of time onto other objects it would only capture individual time, they have to sync up somehow and gravity affects it so its not just matter, its the impression of matter onto the fabric of space

Space has no 'fabric'. Space is not a physical entity, but a set of coordinates.
