We know that the speed of light is not constant? From Wikipedia: it has been suggested in various theories that the speed of light may have changed over time. No conclusive evidence for such changes has been found, but they remain the subject of ongoing research.
From theorized by some to "we know" is about as far apart as one side of the universe is to the other in the realm of science.
