STEPHEN WEBB

Si hay unos 400 mil millones de estrellas tan solo en nuestra Galaxia, y alrededor de 400 mil millones de galaxias en el universo, parece razonable que en algún lugar de ahí fuera, en un cosmos de 14 mil millones de años de existencia, haya, o alguna vez haya habido, al menos una civilizacion tan avanzada como la nuestra. La mera inmensidad de los numeros casi nos obliga a admitir la veracidad de esta hipotesis. Pero, entonces, ¿por que no hemos encontrado ninguna señal, ningun mensaje, ningun artefacto de esos extraterrestres? En esta edicion, revisada y ampliada a conciencia, de esta conocidisima obra de Stephen Webb, el autor desmenuza en detalle las 75 soluciones mas convincentes e interesantes (por el momento) de la celebre paradoja de Fermi: si las cifras apuntan con fuerza a la existencia de civilizaciones extraterrestres, ¿por que no hemos encontrado ningun signo de ellas?

Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials? In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most cogent and intriguing solutions to Fermis famous paradox: If the numbers strongly point to the existence of extraterrestrial civilizations, why have we found no evidence of them?Reviews from the first edition:"Amidst the plethora of books that treat the possibility of extraterrestrial intelligence, this one by Webb is outstanding. Each solution is presented in a very logical, interesting, thorough manner with accompanying explanations and notes that the intelligent layperson can understand. Webb digs into the issues by considering a very broad set of in-depth solutions that he addresses through an interesting and challenging mode of presentation that stretches the mind. An excellent book for anyone who has ever asked Are we alone?." (W. E. Howard III, Choice, March, 2003)"Fifty ideas are presented that reveal a clearly reasoned examination of what is known as The Fermi Paradox. For anyone who enjoys a good detective story, or using their thinking faculties and stretching the imagination to the limits Where is everybody will be enormously informative and entertaining. Read this book, and whatever your views are about life elsewhere in the Universe, your appreciation for how special life is here on Earth will be enhanced! A worthy addition to any personal library." (Philip Bridle, BBC Radio, March, 2003)Since gaining a BSc in physics from the University of Bristol and a PhD in theoretical physics from the University of Manchester, Stephen Webb has worked in a variety of universities in the UK. He is a regular contributor to the Yearbook of Astronomy series and has published an undergraduate textbook on distance determination in astronomy and cosmology as well as several popular science books. His interest in the Fermi paradox combines lifelong interests in both science and science fiction.

In Out of this World, Stephen Webb examines these theories. After introducing general relativity and quantum mechanics - the twin foundations of 20th-century physics - he explains how these two theories simply cannot both be true. Then, in a series of chapters, he introduces us to the seemingly outlandish and bizarre ideas that astronomers and physicists have come up with to account for this apparent theoretical inconsistency, ultimately leading us to wholly new realms of understanding that many scientists and mathematicians are now proposing.

Chris and Stephen off Gogglebox are known and loved by millions of viewers for their outrageous humour, filthy language and adorable sausage dogs. But theres a lot more to them than that. The ex-partners have both had their fair share of ups and downs, and here in their joint memoir they carry us through their experiences on a wave of hilarious back-and-forth conversations and killer one-liners. From their childhoods to finding fame on Gogglebox, nothing is off-limits.Stephen: "Going to the allotment was something wed look forward to. Especially when it got dark and we used to nick everyones vegetables"Chris: "We lived in this flint house on the edge of the cemetery, and not surprisingly it was really haunted."Funny, frank and pretty ridiculous, this is the perfect book for any Gogglebox fan.
