Is anything on Earth--- 4 dimensional? 2 dimensional? 1 dimensional? As you can see now, I'm really confused. And I apologize for the question. I was always taught that I am living exclusively within a three dimensional Earth. Is there anything in or on Earth that is one dimensional? I think that I was taught that one dimension was simply directional lines that could only be preceived as a thought. I think that we learned that two dimensions were designs, figures, flat drawings but had zero depth and could only be preceived as a thought. The way I learned it was that the fourth dimension was basically a combination of two or more of the three dimensions; and that they were not tied to any location and that they could freely move through each other. I'm sure that all this is hopelessly simplified, but the only answer that I am trying to get is whether there are only three dimensions on Earth.
