momentum dimensional ideology

This new view is much different than the traditional view of dimensions. The traditional view is that each dimension is almost unrelated to the other it seems. Like a flat land has no relation to space(3 dimensions) except through the plain it is its own plain. This all seems to be true based on logical reason and can't be proven wrong by any means. The only thing I find hard to understand is time through this train of thought so I am merely just making a new aspect to prove higher dimensions. we live in three dimensions moving in the fourth dimension time.

Lets use an example. What should we name him? Let's call him pal. Pal has a jet pack; yes a jet pack. He is falling towards a gravitational entity. Pal is going in one direction; down. Pal lives in 2 dimensions going one direction he can slow or speed up his fall. this is an example of momentum dimensional ideology.
