The implication was startling. the relationship of these two constants not only linked light to the interaction of magnetism and electricity, but it also indicated that since the speed of light is the reciprocal of the square root of magnetic and electric constants multiplied, the speed of light must be a constant also.
When Maxwell saw the relationship between magnetism, electricity and light, he suggested that maybe there was also a link to gravity as well. However, he never pursued that hunch. I found this little comic strip out on the internet to commemorate that place in history with a tongue-in-cheek conversation that really did not occur, but it makes a point with a some subtle humor.
