"The Hidden Reality" reveals how major developments in different branches of fundamental theoretical physics -- relativistic, quantum, cosmological, unified, computational -- have all led us to consider one or another variety of parallel universe.

"Con miles de millones de años de ser testigo de la vida en la Tierra, de ver a cien mil millones de humanos en su vida cotidiana, de sentirse increíblemente sola y de escuchar su propia historia contada por otros, a la Vía Láctea (con sus cien mil millones de estrellas y cincuenta undecillones de toneladas de gas) le gustaría hablar por sí misma. Todo comenzó hace unos trece mil millones de años, cuando las nubes de gas esparcidas por el...

Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy.

"Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole's core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics....

In exhilarating and behind-the-scenes detail, Panek takes his readers on a tour of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled the search, redefined science, and reinvented the universe. Science journalist Panek (The Invisible Century) offers an insider's view of the quest for what could be the ultimate revelation: the true substance of the unseen dark matter and energy that makes up some...

Program 5: Discusses Hawking's specialty, black holes. With the invention of radio astronomy over 50 years ago many astronomical discoveries came to light including ultraluminous quasars, wormholes, black holes and singularities. Such discoveries seem to allow for the possibility of instant travel over millions of miles of space or even time travel and have led to SETI -- the search for extra-terrestrial intelligence -- looking for stray alien communications. Program...

"Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation...
