When looking for explanations to a mystery, the best debugging method is to look at edge-cases. You eliminate all unimportant noisy data and begin to focus on the data that at least has the potential to cause the mystery. Ideally that data doesn’t change. Ideally it is a constant signal within the noise. Some underlying and unchanging constant.

The speed of light has always struck me as one of the more constant, arbitrary, and yet vital pieces of data we know about our universe. Suitable for debugging whatever kind of reality is is that we find ourselves inhabiting.
