Good way of putting it across. However since we do see the propagation of EM waves, therefore the detrius from Big Bang does exist in the form of space time, and yes probably EM waves uses these mediums...

From another viewpoint, all energetic moving phenomena from atomic explosions, comets (tails), and the big bang degrade as they progress. Heisenburg's principle demands it; They leave detrius behind. In the case of the big bang, I just feel that the detrius left behind we happen to call space-time. It's either there or not. If it's there, it's a medium. If it's a medium, it constrains the speed of light (EM).
