Faster than light but wiser than Big Bang, 21. August 2008
Interesting news! What is the point? The author, a theoretic physicist and professor explains his speculations to an audience that needs not be experts in astro-physics. He pondered about light travelling faster in the beginning of times as it is today. Why is this necessary? Did Einstein not prove that the speed of light is fixed? Yes, but meanwhile we have observed many phenomenons that do contradict to the general scientific "opinions".
Magueijo could be of help to solve the old problems of astro-physic, he already solved some contradictions with the assumption that: "Shortly after the Big Bang light moved infinitely fast through the space and could thereby reach all spots, before it became slower!"
We know that we lose the feeling for space and time when we leave the gravitation of the earth. It seems that we are in a system of space and time all over the universe. Within these limitations of the universe the laws of nature are in command. But we do not know what outside is. Therefore we can only make statements about the inside. Should not be the same true for the time before we began to think of time?
The universe started with a Big Bang some scientist say, others say it was created. The creation theory would suggest that God started the creation from one moment to the next and made the things necessarily with a look of age. This would instantly solve a big bunch of astro-questions, but it would not stop the critics. They say that the light of the stars need years and even millions of years to reach the eye of an earthly observer. Therefore God would be an imposter if he had created the light beam at the same time to make the distant stars visible. The new explanation would negate this reproach. If light could have been everywhere at the same time after the Big Bang, why should the same not be possible in a moment of creation? Why should a creation limit anything which was created?
The fact is that we cannot trace the time back, nor can we force space. That should never be forgotten. Interesting is that the theories of Einstein are relativized again to a significant extent. Scientific magazines stated that with the new theories of Magueijo the history of the emergence of the universe must be rewritten. But again there is also a chance to cancel the Big Bang theory what so many scientists propose.
How is it possible that an explosion makes the ruins go together in perfect order to fly around in an orbit? This is what all galaxies and stars and planets and moons do I space! The result of an explosion? Whence comes the force vertical to the trajectory and pressing the debris in a nicely ordered course? How is it possible that the force stops in the right moment to make the orbit not elliptic but round? The technicians of the NASA are no fools, they know that they have to correct the trajectory of the sondes with a sophisticated control engineering, while ignoring the wonder that the planets in our solar system must be directed in the same way by a force the origin of which is of the same or even higher sophistication. No chance for chance!
The author has never experienced that the result of an explosion is anything else than chaos. But what we see is highest perfection in the universe, in the macro cosmos, but also in the micro cosmos and everywhere between!
Chaos would be the situation after a Big Bang. How can an explosion induce the debris to form a system of mutual balanced order? Classical mechanics do not teach this nor does the pure human reason count on it. With thinkers among the scientists like Magueijo it is possible to leave the unfruitful path of the official theories that can only serve concepts of naturalistic philosophy, but not to the development of science to the discovery of the real natural causes of our existence.
This at last is what the author could have pointed out additionally.

Intriguing, Insightful, engaging and fun, 14. Juli 2008
Who thought reading about space and time and theory of universe would be so entertaining ? I for one have tried some books about this theme and couldn't quite finish any one of them. I always tend to get bored and kind of drop out in the middle. But after a strong recommendation from a friend of mine, I got my hands on this one. It kind of lays out the concept of relativity, the time & space and other details of the universe for all those guys out there who doesn't want to get their hands dirty with maths, but still want to understand something about the universe, space and time. Of course as the author points out, its hard to bring all these dimensions to imagination without mathematics, but he does a very good job of giving us an idea about this area in quite an engaging way. I especially like the british sense of humour slowly creeping up into the book and dominating it. Its a definite recommendation for any guy who is curious about this area.

A fast-paced text..., 23. März 2006
Joao Magueijo's book `Faster than the Speed of Light' is an intriguing look into some of the `bleeding edge' theoretical realms of cosmology and theoretical physics, while also charting an all-too-familiar pattern of academic jealousy, intrigue, and the attempt by the established powers-that-be, the keepers of the dogmatic domain, to downplay those ideas (or persons) that might present significant challenge to their fields. In many ways, this is not unlike church structures of the past that saw it necessary to force thinkers such as Galileo to recant his scientific positions; alas, academic politics has always been among the more nasty of the forms of politics (Kissinger made this observation comparing the realms of academic politics with `realpolitik'); Mageuijo makes no secret about those he respects and those he does not in this text - one assumes he has a secure, tenure position somewhere, or a text like this could cost him such an opportunity.The science itself is intriguing - he traces in a somewhat disjointed way the pattern of physics discoveries that led up to the solidification of the `law of physics' that nothing travels faster than the speed of light, and that the speed of light (the term `c' in Einstein's famous equation E=mc-squared) is constant across all frames of observational reference. This constancy was not Einstein's idea - it was a discovery twenty years prior by Americans Michelson and Morley; Einstein incorporated it into this Special Theory of Relativity in 1905, and the game was afoot for the developments of twentieth-century physics and astronomy. Mageuijo discusses the development from these beginnings, as well as many of the problems and questions that were not solved from the beginning. The scientific exposition can become very complex - for example, Mageuijo's discussion of M-theory and Planck-sized strings (one-dimensional objects) and membranes (planar objects) `living in' eleven dimensions despite the four-dimensional space-time that we see becomes very difficult to follow. This book does not have much by way of equations (it is meant for a general audience rather than a scientifically elite audience), and mathematical structures do not always translate well into conversational English. Perhaps the primary item of note in this text is Mageuijo's idea of the Varying Speed of Light (VSL). Mageuijo mentions early in the text that even Einstein had a paper published (in 1911, after the Special Theory of Relativity but prior to the General Theory of Relativity) on the varying speed of light, but that this idea was jettisoned - rightly so, Mageuijo states, as that particular theory was wrong, but it nonetheless demonstrated that the sanctity of the constancy of the speed of light has never been complete. Mageuijo discusses his VSL theory in some detail (albeit without the mathematics to back it up, a decided drawback for this text; however, one assumes that mathematically-trained scholars will be able to find some such material for analysis), including some objections (scientific and mathematical as opposed to personal/professional) and the attempts to get around the problems raised. Overall, this is a fascinating book. It is rough around the edges (Mageuijo is a physicist, not a professor of English), but the ideas contained within are intriguing, and the story of the fight to get some recognition for a rogue idea (remember, please, that the idea that the earth and planets went around the Sun, rather than all the rest revolving around the earth, was once considered a rogue and radical idea, a threat to the stability not only of science but of society in general) meshed with the academic politics shows that no profession, however lofty and grand, is immune to the human foibles that beset us all.
