http://en.wikipedia.org/wiki/Jo%C3%A3o_MagueijoHe is a pioneer of the varying speed of light (VSL) theory of cosmology, which proposes that the speed of light was much higher in the early universe, of 60 orders of magnitude faster than its present value. It is presented as an alternative to the more mainstream theory of cosmic inflation. The model was first proposed by John Moffat, a Canadian scientist, in 1992.
Magueijo discusses his personal struggles pursuing VSL in his 2003 book, Faster Than The Speed of Light, The Story of a Scientific Speculation.
Magueijo is the host of the Science Channel series, João Magueijo's Big Bang, which premiered on May 13, 2008.
http://en.wikipedia.org/wiki/Varying_speed_of_lightThe variable speed of light (VSL) concept states that the speed of light in vacuum, usually denoted by c, may not be constant, for some reason. In most situations in condensed matter physics when light is traveling through a medium, it effectively has a slower speed. Virtual photons in some calculations in quantum field theory may also travel at a different speed for short distances; however, this doesn't imply that anything can travel faster than light. While it is usually thought that no meaning can be ascribed to a dimensional quantity such as the speed of light varying in time (as opposed to a dimensionless number such as the fine structure constant), in some controversial theories in cosmology, the speed of light also varies by changing the postulates of special relativity. A fundamental change to relativity is needed if c is changing because relativity shows that space and time are equivalent.
