An experiment by Armand Fizeau and Leon Foucault attempted to measure this value.
An experiment by Armand Fizeau and Leon Foucault attempted to measure this value. Cherenkov radiation is produced when this value is exceeded. This quantity is the same in every inertial reference frame, which was proven by the Michelson-Morley experiment. In an equation derived by Albert Einstein, energy energy equals mass times this quantity squared. In a vacuum, this quantity is approximately 300 million meters per second. For 10 points, name this fundamental constant denoted by the lowercase letter c, the fastest speed at which an object can travel.
