Several hypotheses for varying speed of light, seemingly in contradiction to general relativity theory, have been published, including those of Giere and Tan (1986) [10] and Sanejouand (2009). [11] In 2003, Magueijo gave a review of such hypotheses.
In 1998, Magueijo teamed with Andreas Albrecht to work on the varying speed of light (VSL) theory of cosmology, which proposes that the speed of light was up to 3 × 10 30 km/s in the early universe.
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 ...
It’s no secret, Albert Einstein was a bonafide genius, but even geniuses get it wrong sometimes.
Along with João Magueijo, Albrecht independently proposed a model of varying speed of light cosmology [4] [5] which posits that the speed of light in the early universe was a trillion times faster in order to explain the horizon problem of cosmology. In the 21st century, Albrecht worked on quantum mechanics, as well as probability and quantum ...
In 2011, the CGPM stated its intention to redefine all seven SI base units using what it calls "the explicit-constant formulation", where each "unit is defined indirectly by specifying explicitly an exact value for a well-recognized fundamental constant", as was done for the speed of light. It proposed a new, but completely equivalent, wording ...
Attempts to incorporate a variable speed of light into physics were made by Robert Dicke in 1957, and by several researchers starting from the late 1980s. VSL should not be confused with faster than light theories, its dependence on a medium's refractive index or its measurement in a remote observer's frame of reference in a gravitational ...
Dropping the latter while keeping the former leads to a new invariance, known as Fock–Lorentz symmetry [1] or the projective Lorentz transformation. [ 2 ] [ 3 ] The general study of such theories began with Fock , [ 4 ] who was motivated by the search for the general symmetry group preserving relativity without assuming the constancy of c .
