Time is a dimension, but not like space

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.
