So I get the first 4 (height, width, depth and time) but I’ve heard lots of scientists mention that there’s up to 12 or 14 or so dimensions on top of that?
In: Mathematics
Mathematical dimensions do not need to relate to physical ones, and physical ones do not need to relate to spacetime. It’s really a mathematical way to look at things. Let’s say you have thing moving around. It has a position (x, y, z), a velocity, a mass that may change over time, and so on. Every one of those components can be considered a dimension in a vector space defining the state of the thing.
