Science Universe

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.

The survivors live underground, as far from the Original World as possible and protected from the ultimate evil, Radiation. Then terrible monsters, who bring with them a screaming silence, are seen and people start to disappear. One young man realizes he must question the nature of Darkness itself.

In this audiobook, astrophysicist Janna Levin blends memoir and visionary science to provide a groundbreaking personal account of her life and ideas.

Thirty-three shorter tales of the Liaden Universe® brought together for the first time in two mega-volumes. Seventeen tales to start with in Volume One! The nationally bestselling Liaden Universe® novels are treasured by space opera aficionados for their wit, world-building, strong characterizations, tender romance, and edge-of-the-chair action.

The first of the seven books set in the Liaden Universe tells a rich and sweeping story of warring families and star-crossed lovers in a fantastic, other-world galaxy.

Assistant Trader Jethri Gobelyn was an honest, hardworking young man who knew a lot about living onboard his family's space-going trade ship; something about trade, finance, and risk-taking; and a little bit about Liadens. It was, oddly enough, the little bit he knew about Liadens that seemed like it might be enough to make his family's fortune, and his own, too. In short order, however, Jethri Gobelyn was about to find out a lot more about Liadens... like how far they might go to protect their name and reputation.

It’s dark outside, but hope will not be defeated. Michael, Akio, Yuko, and the rest are searching for the pieces necessary to put together a craft which Michael hopes will take him to Bethany Anne. But first, there are idiots in his way, seeking the same parts and intend to take them. By force. The challenge is they will find out what ‘force’ truly means when they dare to go up against the Dark Messiah. One way or another, Michael will get back to Bethany Anne.

Follow a core group of characters known as the Trailblazers, as they use alien technology and knowledge discovered in Antarctic ruins, to obtain limited immortality, and lead Humanity out into the galaxy, encountering, befriending, and fighting, hundreds of alien races, all the while desperately trying to prepare Earth for the unbeatable threat at the core of the Milky Way that is destined to return, and reclaim their lost colony - and their former human slaves.

For centuries, it was assumed that our universe was static. In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

As you read this, billions of neutrinos from the sun are passing through your body, antimatter is sprouting from your dinner and the core of your being is a chaotic mess of particles known only as quarks and gluons. If the recent discovery of the Higgs boson piqued your interest, then Why the Universe Exists will take you deeper into the world of particle physics, with leading physicists and New Scientist exploring how the universe functions at the smallest scales.

Star Wars: Heir to the Empire: Behind the Scenes is a special recording that features new commentary by author Timothy Zahn and editor Betsy Mitchell, written for the 20th anniversary edition of Heir to the Empire, read by Zahn and Mitchell. Included here is audio from the that new unabridged recording to enhance their comments.

Follow a core group of characters known as the Trailblazers as they use alien technology and knowledge discovered in Antarctic ruins to obtain limited immortality and lead humanity out into the galaxy, encountering, befriending, and fighting hundreds of alien races all the while desperately trying to prepare Earth for the unbeatable threat at the core of the Milky Way that is destined to return and reclaim their lost colony...and their former human slaves.

A physicist speeds across space, time, and everything in between showing that our elegant universe from the Higgs boson to antimatter to the most massive group of galaxies is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper-drive tour of the universe like this one.

Thierry Thackeray is having the worst week ever. Her ex is back in town, death omens are camping out on her mother's lawn and her estranged father has gone missing. Then there's the small matter of the High Court requesting her presence in Faerie. Now the wrong fae has answered her summons, and she's stuck with a not-so-charming prince who offers to fix all her problems . . . for a price. She can't afford to tell him no, but with her luck, she might not survive saying yes.

On April 10, 2019, award-winning astrophysicist Heino Falcke presented the first image ever captured of a black hole at an international press conference - a turning point in astronomy that Science magazine called the scientific breakthrough of the year. That photo was captured with the unthinkable commitment of an intercontinental team of astronomers who transformed the world into a global telescope. While this image achieved Falcke’s goal in making a black hole “visible” for the first time, he recognizes that the photo itself asks more questions for humanity than it answers.

Billy Boustany had the adventure of a lifetime. Now, all he wants to do is to go back to the amazing universe he discovered. But the power brokers over there warned him to stay away and keep his mouth shut. At the same time, Diyami Red Hawk, an idealistic young man from that universe, has connected with Billy’s daughter and is on a mission to build a modern Native American city in our world. But he’s getting nowhere—until he finds support in unexpected places.

Michael continues to work to fulfill the promise to his love, but the world isn't the same place. Now, there is a mistake he made centuries in the past walking around he needs to rectify.

Further, the effort to pull together the Sacred Clan's ship parts are starting to come together. Unfortunately, no one wishes to give Michael and his new family any help.

Does alien life exist? Is time travel possible? How did the universe begin, and how will it end? Is the future predetermined? These are just some of the fascinating questions posed in this book, which stretches across physics, the life sciences and cosmology. Each chapter considers a separate question and ends with either an answer or, if there is insufficient evidence, a ‘best guess’ answer.

Exiled from Liad after bombing a city to save it from The Department of the Interior’s infernal weapons and plans, Clan Korval has gone to ground on the back-water planet Surebleak, whose people are as untamed as its weather. The old Boss-controlled fiefdoms largely fell to Pat Rin yos’Phelium’s influence, but the world is restive, the influx of outworld lawyers, guns, and money a brewpot for armed dissatisfaction.
