Faster than the Speed of Light? VSL Theory Says, “Yes”

A brilliant young physicist Joăo 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.


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.
