Interestingly enough most kinds of spaces in
Topology do not use findigs from theory of electromagnetism as part of their definition...
That said everything we know about physical world we live in is just working hypothesis or a theory - we still do not know everything, or more importantly - how four fundamental forces work. If you
remove part of EM can you even construct space with other three forces? I think CS/IT forum isn't the place where one could expect to see a good explanations to such questions.
