Hey everyone, I'm not a physicist, I'm a high school senior with a who stopped taking math and science after sophomore year (which I sorely regret). So, I have a question rather than a crazy hypothesis regarding the primordial cocktail antecedent to the big bang that's dubious at best. Call me naive, but I'm curious as to the recognition of length, width, and depth as independent dimensions. Why not just "Space"? Is it that Length, Width, and Depth constitute space? or is it that each dimension is independent of the next? I understand that Depth depends on Width, and Width depends on Length, which is why they are sequential, but is Width independent of Depth, and Length of Width? Further, what defines a Dimension? It seems to me that Length and Width are entirely intangible and abstract measurments without Depth. Again, I'm just curious, I'm not here to challenge anything.
