Robert Dicke, in 1957, developed a VSL theory of gravity, a theory in which (unlike general relativity) the speed of light measured locally by a free-falling observer could vary. [7] Dicke assumed that both frequencies and wavelengths could vary, which since c = ν λ {\displaystyle c=\nu \lambda } resulted in a relative change of c .
In 1992, John Moffat proposed that the speed of light was much larger in the early universe, in which the speed of light had a value of more than 10 30 km/s. [2] He published his " variable speed of light " (VSL) theory in two places—on the Los Alamos National Laboratory's (LANL) online archive, 16 Nov. 1992, [ 4 ] and in a 1993 edition of ...
Magueijo discusses his personal struggles pursuing VSL in his 2003 book, Faster Than The Speed of Light, The Story of a Scientific Speculation. He was associated with a misunderstanding over priority concerning VSL with John Moffat. He was also the host of the Science Channel special João Magueijo's Big Bang, [1] which premiered on 13 May 2008.
Willem de Sitter's argument against emission theory. According to simple emission theory, light moves at a speed of c with respect to the emitting object. If this were true, light emitted from a star in a double-star system from different parts of the orbital path would travel towards us at different speeds.
In such a theory, its speed would depend on its frequency, and the invariant speed c of special relativity would then be the upper limit of the speed of light in vacuum. [32] No variation of the speed of light with frequency has been observed in rigorous testing, putting stringent limits on the mass of the photon. [59]
The horizontal axis is comoving distance, the vertical axis is conformal time, and the units have the speed of light as 1. For reference . The theory of cosmic inflation has attempted to address the problem by positing a 10 −32 -second period of exponential expansion in the first second of the history of the universe due to a scalar field ...

A 2008 quantum physics experiment also performed by Nicolas Gisin and his colleagues has determined that in any hypothetical non-local hidden-variable theory, the speed of the quantum non-local connection (what Einstein called "spooky action at a distance") is at least 10,000 times the speed of light.
