A thrilling exploration of competing cosmological origin stories, comparing new scientific ideas that upend our very notions of space, time, and reality.
 
By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.
 
Incorporating insights from Afshordi’s cutting-edge research and Halper’s original interviews with scientists like Stephen Hawking, Roger Penrose, and Alan Guth, Battle of the Big Bang compares these models for the origin of our origins, showing each theory’s strengths and weaknesses and explaining new attempts to test these notions. Battle of the Big Bang is a tale of rivalries and intrigue, of clashes of ideas that have raged from Greek antiquity to the present day over whether the universe is eternal or had a beginning, whether it is unique or one of many. But most of all, Afshordi and Halper show that this search is filled with wonder, discovery, and community—all essential for remembering a forgotten cosmic past.

Bennu, named for the ancient Egyptian phoenix, was the chosen destination of OSIRIS-REx, NASA’s premier mission of asteroid exploration, launched in 2016. Study of the asteroid is important in safeguarding the future of planet Earth, but Bennu is also a time capsule from the dawn of our Solar System, holding secrets over four-and-a-half billion years old about the origin of life and Earth as a habitable planet.

In 2020 the OSIRIS-REx spacecraft successfully landed on the surface of Bennu and collected pristine asteroid material for delivery to Earth in September 2023. Scientific studies of the samples, along with data collected during the rendezvous, promise to help find answers to some of humanity’s deepest questions: Where did we come from? What is our destiny in space?

This book, the world’s first complete (and stereoscopic) atlas of an asteroid, is the result of a unique collaboration between OSIRIS-REx mission leader Dante Lauretta and Brian May’s London Stereoscopic Company. Lauretta’s colleagues include Carina Bennett, Kenneth Coles, and Cat Wolner, as well as Brian May and Claudia Manzoni, who became part of the ultimately successful effort to find a safe landing site for sampling. The text details the data collected by the mission so far, and the stereo images have been meticulously created by Manzoni and May from original images collected by the OSIRIS-REx cameras.

By day, every year over 40,000 visitors pour in. Across the Rio Grande, a hundred miles away, Mexican mountaineers use the white domes as landmarks. By night, perched almost 7,000 feet above the sleeping, earthbound world, astronomers probe the secrets of the night sky. This is the University of Texas McDonald Observatory, one of the world's largest university-operated astronomical installations.

Big and Bright: A History of the McDonald Observatory is the story of a remarkable collaboration between two major universities, one a prestigious private school, the other a growing southwestern state institution. The University of Chicago had astronomers, but its Yerkes Observatory was aging and underfunded; the University of Texas had money for an observatory but no working astronomer to staff it. Out of their mutual need, they formed a thirty-year compact for a joint venture. Unusual in its day, the Yerkes-McDonald connection presaged the future. In this arrangement, one can see some of the beginnings of today's consortium "big science."

Now the McDonald Observatory's early history can be put in proper perspective. Blessed with a gifted and driving founding director, the world's (then) second-largest telescope, and an isolation that permitted it to be virtually the only major astronomical observatory that continued operations throughout World War II, the staff of McDonald Observatory helped lay the foundations of modern astrophysics during the 1940s. For over a decade after the war, a lonely mountaintop in West Texas was the mecca that drew nearly all the most important astronomers from all over the world.

Based on personal reminiscences and archival material, as well as published historical sources, Big and Bright is one of the few histories of a major observatory, unique in its focus on the human side of the story.
