When Walter explain to Jack the simplicity of how the universe worked, he wondered why everything human saw was so complicated. The reason was because the universe is made up of twenty five dimensions which all have to be taken into account when calculating anything. Most dimensions will have no noticeable affect on day to day human life. But on extreme scales they have enormous influence.
Human science needs complicated math because it does not know about the effects of anything beyond four dimensions. But if the others are taken into account, the equations become much simpler, although much longer in many cases.
The laws of physics are the same everywhere in all dimensions, but each dimension has a field associated with it which can interact and affect the others. Some of the dimensions are also compressed or warped in areas, doing the same to underlying dimensions.
