Faster than the Speed of Light? A New Theory Says, Yes

[via daily galaxy]

A brilliant young physicist João Magueijo asks the heretical question: What if the speed of light—now accepted as one of the unchanging foundations of modern physics—were not constant?

Magueijo, a 40-year old native of Portugal, puts forth the heretical idea that in the very early days of the universe light traveled faster—an idea that if proven could dethrone Einstein and forever change our understanding of the universe. He is a pioneer of the varying speed of light (VSL) theory of cosmology -an alternative to the more mainstream theory of cosmic inflation- which proposes that the speed of light in the early universe was of 60 orders of magnitude faster than its present value.

Vsl Solving the most intractable problems of cosmology in one brilliant leap, Magueijo’s varying-speed-of-light theory (VSL) would have stunning implications for space travel, black holes, time dilation, and string theory—and could help uncover the grand unified theory that ultimately eluded Einstein.

Joao Magueijo's radical ideas intend to turn that Einsteinian dogma on its head. Marueijo is trying to pick apart one of Einstein’s most impenetrable tenets, the constancy of the speed of light. This idea of a constant speed (about 3×106 meters/second) -is known as the universal speed limit. Nothing can, has, or ever will travel faster than light.

Magueijo -who received his doctorate from Cambridge, has been a faculty member at Princeton and Cambridge, and is currently a professor at Imperial College, London- says: not so. His VSL theory presupposes a speed of light that can be energy or time-space dependent.

In his fist book, Faster than the Speed of Light, Magueijo leads laymen readers into the abstract realm of theoretical physics, based on several well known, as well as obscure, thinkers. The VSL model was first proposed by John Moffat, a Canadian scientist, in 1992. Magueijo carefully builds the foundations for a discussion of Big Bang cosmology, and then segues into the second half of the book, which is devoted to VSL theory.

Like most radical, potentially seminal thinkers, Magueijo shakes the foundations of the physics community, while irritating off many of his fellow scientists. VSL purposes to solve the problems at which all cosmologists are forever scratching: those inscrutable conceptual puzzles that surround the Big Bang. Currently many of these problems have no widely accepted solutions.

Could Einstein be wrong and Magueijo right? Is he a gadfly or a true, seminal genius? Time will tell.
