the (*) index of refraction of a material, and, according to relativity, it is invariant for all observers.
The force per unit area of the Casimir effect is equal to this quantity times h-bar times pi-squared all over 240 times distance to the fourth power, and an object's Schwarzchild radius is inversely proportional to the square of this quantity. This quantity is equal to a certain quantity times the (*) index of refraction of a material, and, according to relativity, it is invariant for all observers. Hypothetical "tachyons" can exceed this value, and OPERA mistakenly claimed they had measured neutrinos going faster than this speed. For ten points, identify this value often symbolized c and approximated as 3 times 10 to the 8th meters per second, the rate at which photons move in a vacuum.
