Is it alright for the main body of my paper to not contain any references?
Not having references in the main body of a paper isn't necessarily a problem, but it can be a major symptom of other factors that will cause you to have difficulty publishing a paper. You may be having trouble finding references because you haven't narrowed down what you are doing enough to find out which other people will be interested in it. 

"Some of it is philosophical, some of it relates to maths and physics as well."
This sounds like you are writing about the philosophy of science, which is a field with a pretty active literature. Perhaps you can read more in that field, and see if any of it sounds like what you are doing?

"the problems that my ideas can possibly solve in other fields": if you think your work can solve important problems in other fields, then there are probably useful references where someone else has attempted to solve the same problem. Explaining how your work differs from these attempts, and where it can improve on them, would be a standard place to include references in the main body. If you cannot find this, you may not have that well-defined a problem yet.

Even if your work has wide applications, it is often useful to choose one specific problem and address that first - this forces you to be specific, address the questions of one field, and make sure that you deal with what other people have done before.
