E = mc2 ist die berühmteste Formel der Welt. Mit ihr brachte Einstein es auf den Punkt: Energie und Masse sind zwei Seiten derselben Medaille und die Lichtgeschwindigkeit c ist ihr Wechselkurs. Doch warum besteht dieses so einfache Verhältnis? Wie ist Albert Einstein zu diesem Schluss gekommen? Und welche Folgen für das Verständnis des Universums ergeben sich daraus? Brian Cox, Professor für Physik und in England durch seine Sendungen auf BBC sehr bekannt, hat sich zusammen mit seinem Kollegen Jeff Forshaw, Professor für theoretische Physik, die scheinbar einfache Einstein-Gleichung vorgenommen, um sie mit viel Energie ausführlich und verständlich zu erklären.
The magnificent vault of stars emblazoning Earth's night skies are but an infinitesimal fraction of the hundreds of billions that inhabit our galaxy - and there are at least as many galaxies in the universe as there are stars in the Milky Way. 1001 Wonders of the Universe makes sense of this dizzying celestial panorama by exploring it one step at a time, illustrating the planets, moons, stars, nebulae, white dwarfs, black holes and other exotica that populate the heavens with an astounding 1001 of science's most spectacular photographs. The book opens with an orbital survey of planet Earth, before venturing into the solar system heading for interstellar space and the heart of our galaxy. As the journey unfolds, the rhythms of stellar life emerge: we pass through dark clouds of dust and gas ablaze with newly smelted stars and we witness dying stars bloom and fade as planetary nebulae, or tear themselves apart as supernovae. Having crossed the Milky Way, we enter intergalactic space. Out here we watch the hidden lives of galaxies: we see them flock and cluster, forming massive conglomerations that span millions of light years, visibly warping space with their tremendous gravity. After covering an almost unimaginable 13.4 billion light years, we approach the edge of space and the dawn of time where our voyage must end, but not before we consider how the universe was born, and how it might die.
This book conveys the thrill of observing strange and surprising features of the universe and the satisfaction gained by understanding them through modern science. Using simple analogies and a wealth of illustrations, Professor Narlikar skilfully steers us through a cosmic journey of discovery, starting from the Earth and solar system and stepping out to the farthest reaches of the universe. Each of the seven wonders represents a range of mysterious phenomena or a class of spectacular events or remarkable cosmic objects that have challenged human curiosity and often defied explanation.

Like detectives sleuthing out the greatest mystery of all, scientists over the centuries have uncovered clues about the structure and origins of the universe. The work of Galileo, Newton, Einstein, and a host of other tenacious researchers and thinkers reveals a cosmos of almost unimaginable wonder and beauty. If we then honestly follow the evidence of science wherever it leads, where do we end up? Karl Giberson takes us on a fascinating guided tour of planets and protons, galaxies and gamma rays. We discover that if gravity were slightly stronger, neutrons a tiny bit lighter, the size of our sun somewhat larger or a dozen other factors altered by fractions, there would be no life. The author shows that for many observers, even those who do not embrace religious faith, all of this looks suspiciously like the expression of a grand plan--a cosmic architecture capable of both supporting life such as ours, and inspiring observers like us to seek out hints of a creator. Join this cosmic expedition and discover the wonder of it all.
