The forces, to be a useful modelling tool, need a medium to interact with matter. E.g. an equivalent of charge would always be zero, if matter didn’t have the ability to have charge. At that point, it effectively doesn’t exist.
Interestingly, the strong, weak and electromagnetic forces are also aspects of the same force. They unify at high enough energy levels. They only appear different. The exception is gravity. It doesn’t fit the mould. Basically we don’t currently have 4 forces, but only 2. Scientists suspect it’s actually only 1, but can’t yet unify gravity into a theory of everything via a theory of quantum gravity.
But isn’t gravity a function of spacetime not matter? Where’s the others are all behaviors of matter? Like there isn’t a gravity partical or a spacetime partical.
