In any case, I realise now I was hypothesising about how one may describe the earth's motion through an imaginary space ("the universe"), limited in the context of this hypothesis to 3 dimensions.
Alan D., could you please explain your theory of a "spiral orbital path of the earth around the sun", and some background as to how you arrived at this theory?
Do you agree with this definition from NASA Knows?

An orbit is a regular, repeating path that one object in space takes around another one.
