Faster than the Speed of Light? A New Theory Says, “Yes” -A Galaxy Insight

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?r276714 1169978 Old Light Faster than New Light?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.
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.

Ok, so if the speed of light slows down enough, time travel is a real possibility? Reboot, where are you?

  1. the speed of light changes as it moves through things, and i think they brought light to a stand still in the laboratory recently.

    light and its relationship to matter is freaky shit.

    there aren’t many constants in the universe, and at one time we thought that time and space were separate and distinct entities which were constant for everyone. Einstein called bullshit on that, and i think it would only be fitting if the speed of light were not so ‘constant’ as we thought.

    does anyone know how this would fit in with the Michelson–Morley experiment?

  2. I’d have to read the book for details of the theory, but probably no time travel or warp drive.
    The write up is kind of bad because obviously you can slow down light be sending through a piece of glass. There have been other theories proposed that the speed of light in the early universe might have been faster due to higher energy density have higher order effects on the space-time curvature. That doesn’t exactly open an possibilities to be build a time machine.
    Here’s something to remember whenever somebody compares themself to Einstein: Einstein was not a lone genius who came up with relativity all by himself and everyone laughed at his ideas. David Hilbert even published the first paper on general relativity several weeks before Einstein. Einstein gets credit for being a genius mostly because he came up with a really simple experiment to prove his theories (measuring star positions during a solar eclipse). Magueijo may be very smart, but until he comes up with an experiment to support his theory, he’s no Einstein.

  3. nyokki, i do not understand your question

    also, Einstein pwns because who the fuck even knows how to pronounce “João Magueijo”?

    i think the last name goes something like “Ma-gwa-ihoe” or something. but i’m not even gonna attempt “João”

    the only hard thing about Einstein’s name is remembering that the ‘e’ comes before the ‘i’ both times

    Reboot shot my hopes down and you lifted them up again.

    In German the vowel sound follows the second vowel. So EI is pronounced like a long i, and IE would be pronounced like a long e.
