An alternative to inflation is explained using its time-evolution by Petit and Moffat as a solution to the horizon problem.
The anisotropy of this quantity is guaranteed in both directions under the external synchronization as provided by Mansouri-Sexl theory. Interactions with a Casimir field between two closely-spaced parallel plates result in an increase in this quantity as per the Scharnhorst effect. An alternative to inflation is explained using its time-evolution by Petit and Moffat as a solution to the horizon problem. This quantity can be calculated using the rotation rate of a mirror as well as the separation between those mirrors using a Fizeau device. It is equal to the inverse square root of the product of the permeability and permittivity of free space and is also the ratio between the electric and magnetic components of an EM-wave. Recently thought to have been exceeded by neutrinos in the OPERA experiment, for 10 points, name this fundamental quantity, about 300 million meters per second in a vacuum.
