Sorry to quibble, but the speed of light as finite number was first "discovered" by Ole Rømer in 1676, arising from his observations of the differences in the timing of the appearances and disappearances of Jupiter's moons as the Earth-Jupiter distance changed with time.

He expressed it as 1 over the square root of (vacuum permeability time’s vacuum permittivity). These vacuum properties can be reduced in the presence of negative energy. This negative energy is defined in terms of a lack of zero-point-energy vacuum fluctuations. This condition does exist in a space known as a casimir cavity. This means it is possible to expand the speed of light to be faster then c. An article related to this can be found in Marcel Urban, François Couchot, Xavier Sarazin, Arache Djannati-Atai. The quantum vacuum as the origin of the speed of light.
