All you know about time is wrong.

Time exists, and the unit of measure fortime also exists.

This is how we see time.

Now that time does not exist as we measure it, this is another kind of fish meal, our way of measuring the passage of time is a human construct based on the cycles of the stars and the planets with their satellites.

That is our perception, but it is not Time.

And time it's not even the fourth dimension, as I keep hearing about it.

Just as space has (for now according to our academical educated guess) 17 dimensions, of which 11 seem to me to have been demonstrated mathematically, but only 5 have been physically experienced concretely and repeatedly, of which in our blindness from the way mother nature made us in the cosmos we perceive only 3 naturally, and time is another set of dimensions that are not space, how many are them?

It is not known, but we naturally perceive only one, and that in a unique sense.
