Hi, I'm new here. I've loved all the qualitative aspects of physics for a while now and I'm just starting to get into some of the more quantitative aspects of physics, the actual math. I'm such a complete amateur at all this and I'm only in high school so please excuse my question if it seems ridiculous. I was thinking about how time is a dimension today and this thought occurred to me. From what I understand, the Planck length is the smallest possible length. Now, it being a length, it would measure a 1 dimensional object. If we were to measure a 2 dimensional object, the curvature of 1 dimensional space, we would measure it in Planck lengths squared, the Planck area I suppose. If we were to measure a 3 dimensional object, the curvature of 2 dimensional space, we would measure it in Planck lengths cubed, the Planck volume I'm assuming. So, from this logic, one would assume if we were to measure something in the fourth dimension of time, the curvature of 3 dimensional space, we would measure it in Planck lengths to the 4th power. But we don't, we measure it in a completely separate unit, the Planck time. Why?
