the 10 dimensions?
In: Physics
As you know, there are three spatial dimensions: length, width, and height.
Einstein’s general relativity added a fourth — time — and treated the whole shebang as a single entity, *spacetime.*
As we gained knowledge of physics, the mathematical equations that we use to model our universe grew more complex, and demanded extra dimensions in order to work.
Specifically, the best model we currently have, M-theory, requires that there be seven additional spatial dimensions in order for the math that governs it to work.
Because its math makes accurate predictions, physicists assume it to be accurate, and so we live in a world of ten spatial dimensions and one temporal dimension, with the seven we can’t experience tucked away somewhere.
