In our Universe, the “element” of fire is really just the occurrence of a chemical combustion reaction. But in the other universe, fire has substance, just as earth, water, or air does.
As such, matches or lighters from our universe do not function in the other because, like everything that comes from our universe, they do not contain any element of “true” fire. They are just ways of starting a combustion reaction.
Combustion chemical reactions, as we understand them in this universe, do not work In other universe. Any technology that relies on combustion (cars, propane torches, etc.) does not function there.
