ELIF: What are the 5th to 9th dimensions?

So my understanding of the spacial and temporal dimensions is limited to the following but I'd like to have a vague understanding of the rest:

1st = x-axis,

2nd = y-axis,

3rd = z-axis, and

4th = time.


Edit: Thank you for the material reddit, continue to post resources if you'd like but I have enough to tide me over for a week of reading/watching here.

There is no way to explain it except by analogy, and no analogy is perfect. For the real explanation you have to do the math.

To see why an analogy is needed, let's consider another analogy. Suppose our world was confined to a table top. We had x and y, but no z. And someone asked "what is this other dimension z?"

Well, there would be no way to point in that direction for them, since they are only table top people, but one of them might say "imagine we lived in a line and only had an x-axis. And someone ask, what is this y-axis?. Well, it would be a direction they could not see."

The point is, the extra dimensions are in directions we cannot see. We cannot even imagine them. They only exist mathematically for us, but we can sort of imagine them by analogy.

Back to your 5^th thru 9^th . In those cases, the dimensions are a little different. They are "curled up, not long". For this analogy, imagine you are looking at a cable or wire from a distance. It looks like it only has an x-axis. If you see a bird on a wire you say it is at x = 5 or something like that.

Now if you focus in real close to wire you see something strange at x = 5, you see the cable has thickness. There is a tiny little curled up circular dimension at x = 5 where little bacteria could be living. You could have a whole ring of tiny bacteria at x = 5. For big things like birds, there is only one dimension, but for very tiny things there is another dimension. That is what the extra dimension are like.
