Imagine a region in space where the force of gravity is so strong that nothing - not even light - can escape. This phenomenon is a black hole: one of the most exotic, mind-boggling, and profound subjects in astrophysics. Nearly everyone has heard of black holes, but few people outside of complex scientific fields understand their true nature and their implications for our universe. No movie, novel, or other fictional treatment of black holes matches Professor Filippenko’s absorbing presentation of the actual science behind these amazing objects.

Alex Vilenkin resume en este audiolibro, de una forma amena y accesible, la historia de las investigaciones de los últimos cincuenta años en torno al origen y la evolución del universo. Vilenkin hace hincapié en dos teorías en las que es especialmente innovador: la inflación eterna del cosmos y la existencia de múltiples universos... en alguno de los cuales tal vez ahora nos hallemos replicados, sosteniendo este mismo libro en nuestras manos.

Once dismissed as a mathematical curiosity, black holes are so strange they almost defy belief. Since their existence was confirmed, research into the nature of black holes has opened up new vistas in physics. In this audiobook, we examine some of the most fascinating discoveries about black hole formation and behavior, the new and evolving research in gravitational wave astronomy, theoretical possibilities such as wormholes, and much more.

It has been argued that science fiction (SF) gives a kind of weather forecast - not the telling of a fortune but rather the rough feeling of what the future might be like. The intention in this audiobook is to consider some of these bygone forecasts made by SF and to use this as a prism through which to view current developments in science and technology.

Os grandes mistérios e maravilhas do céu noturno sempre nos fascinaram, intrigaram e divertiram, desde os primeiros passos na Terra. Hoje, continuamos nos esforçando para entender o nosso lugar no cosmos. O século 20 foi palco de importantes e assombrosas descobertas sobre o nosso próprio planeta, o sistema solar, as estrelas e as galáxias. Contudo, ainda buscamos respostas para inúmeras questões, e essa busca nos proporciona uma valiosa compreensão da vastidão e das infinitas possibilidades do espaço universal que ainda estamos por descobrir.

Instead of “what if the South won the Civil War?” cosmologists ask, “what if the constants that make up the fundamental building blocks of physics were different?” Physicists argue that any slight change to the laws of physics would mean a disruption in the evolution of the universe - and our existence. With the many factors that had to align for us to exist, it can seem like the laws of physics might seem finely tuned to make our existence possible. Instead of a supernatural or divine explanation, this book explores the possibility is that our universe isn’t the only one.

Our nearest planetary neighbor has been the subject of endless fascination and wide-ranging theories throughout history. Is there life on Mars? Was there ever life on Mars? What was the atmosphere like thousands or millions of years ago? From Percival Lowell, who built his own observatory so he could dedicate himself to studying the red planet, to NASA landing the car-sized Curiosity rover in 2012, this book traces Scientific American's coverage of the observation and exploration of Mars.

This audiobook is about the American moon landings - and about the doubts expressed ever since concerning the reality of these landings. Were the images of men on the moon really just a huge and cleverly executed hoax? Eversberg explains the best-known claims and conspiracy theories

In the two decades since astronomers first discovered the existence of a planet outside of our solar system, “exoplanetology” has become the hottest specialty in astrophysics. Scientists young and old, inspired by the thought of finding either another habitable world or the Holy Grail of space exploration - life itself - flocked to be part of this burgeoning field. With so much brainpower on hand, it’s no wonder that investigative techniques advanced more quickly than anyone would have thought.
