If sound waves travel by pushing particles back and forth, then how exactly do electromagnetic/radio waves travel through the vacuum of space and dense matter? Are they emitting… stuff? Or is there some… stuff even in the empty space that they push?

Sound is nothing more than the vibration of those particles being pushed around. Electromagnetic/radio waves are actually energy itself, which doesn’t require a medium in order to move.
