In Faster Than the Speed of Light: The Story of a Scientific Speculation physicist João C.R. Magueijo proposes a startling theory: the speed of light is not an unalterable constant, as Albert Einstein had asserted. Breaking ranks with accepted theories, Magueijo believes that the speed of light was actually faster soon after the Big Bang—the event that scientists believe created the universe—than it is today. By making this assumption, now called the varying speed of light (VSL) theory, it might become easier to resolve some of the problems with the current Big Bang Theory, as well as theoretical problems that have thus far prevented the discovery of a Grant Unified Theory that will explain how all the forces in nature operate.

Magueijo makes the case for change in the speed of light carefully. "Leaning on several well known, as well as obscure, thinkers," reported FrontWheelDrive. com contributor Brandon Pierce, "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." Labeled an iconoclastic rebel by some scientists, Magueijo has complained that many researchers and academics get bogged down by generally accepted theories, which prevents them from thinking in new ways in order to solve some of science's most puzzling predicaments. This was true even with Einstein, according to Magueijo, who told a New Scientist interviewer that Einstein's "view that mathematical beauty is important is responsible for all the string theory crap about ‘elegant’ theories. Einstein wasn't like that when he was young."

Magueijo's attitude toward the scientific community is apparent in Faster Than the Speed of Light, lending the book an aggressive tone about which many reviewers have commented. For example, a Kirkus Reviews contributor said that the author's "obvious lack of interest in pretending to be polite to those he has identified as enemies makes this one of the more scathing scientific memoirs of recent years." Booklist critic Donna Seaman similarly noted that "Magueijo is exhilaratingly frank in his condemnation of the creativity-killing politics and bureaucracy of science."

More forcefully, Catherine H. Crouch declared in Books & Culture: "The second half of Faster Than the Speed of Light is filled with griping that ranges from petty complaints to crude, infantile attacks. One of the many objects of his spleen is the process of obtaining grants for scientific research. According to Magueijo, middle-aged scientific bureaucrats, threatened by new ideas, try to frustrate the work of their few genuinely productive colleagues by burdening them with administrative duties." But although Magueijo can be opinionated, a Publishers Weekly writer asserted that "his science is lucidly rendered, and even his penchant for sturm und drang sheds light on the tensions felt by scientists incubating new ideas."

"And this is exactly how science progresses," Pierce declared. "In reality, it's experimentation and exploration. It's throwing around ideas, destroying old theories, salvaging the useful parts, and rebuilding. It's bouncing ideas off your peers, collaborating, in a process that can be just as painful as productive." "Whatever the final verdict on VSL, where experimental results will act as the ultimate referee," stated Guardian contributor Manjit Kumar, "Magueijo and his collaborators have developed a theory that is now being taken seriously, against all the odds. As the young Einstein once remarked: ‘Foolish faith in authority is the worst enemy of truth.’"

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
