Space Universe

Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream - to improvise and rely on intuition. His approach leads him to three principles that shape all theories of the universe: the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries.

Humanity's greatest export - Justice. Space is a dangerous place, even for the wary, especially for the unprepared. The aliens have no idea. Here comes the Bad Company. Colonel Terry Henry Walton takes his warriors into battle, for a price, in this first installment of The Bad Company. He believes in the moral high ground and is happy getting paid for his role in securing it.

The planet Vok is holding its first free elections after years of oppressive military rule. Captain James T. Kirk and the crew of the Starship Enterprise have been dispatched by Starfleet to serve as impartial observers, but remaining neutral proves a challenge, as Kirk confronts a tangled web of scandal, conspiracy, and assassination plots - with the stability of an entire sector at stake. To make matters worse, Dr. Leonard McCoy has vanished while on a mission of mercy to Braco, a nearby planet only a system away.

Women physicists and astronomers from around the world have transformed science and society, but the critical roles they played in their fields are not always well-sung. Her Space, Her Time, authored by award-winning quantum physicist Shohini Ghose, brings together the stories of these remarkable women to celebrate their indelible scientific contributions. Her Space, Her Time is a story of innovation, leadership, and overcoming invisibility that will leave a lasting impression on any listener curious about the rule-breakers and trendsetters who illuminated our understanding of the universe.

As a kid, Aomawa Shields was always bumping into things, her neck craned up at the sky, dreaming of becoming an astronaut. A year into an astrophysics PhD program, plagued by self-doubt and discouraged by a white male professor who suggested that she—a young Black woman who also loved fashion, makeup, and the arts—didn’t belong, she left astronomy and pursued acting professionally for a decade, before a day job working for NASA’s Spitzer Space Telescope drew her back to the stars.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

The sky is not the limit. From an alley in New York to an interstellar wormhole, the path to the future looks different for everyone. These cosmic short stories from some of today’s most influential Black authors reveal a universe of possibilities.

The Zak'de'ron take note of the Rit'ko'sor joining Star Force, making contact, and making their wishes known...but in the process, they make a critical mistake that will forever alter their relationship with the trailblazers.

MALS Theory envisages three rings of galaxies, for simplicity. An Inner; a Middle and an Outer set of galaxies. The Inner galaxies traveling the slowest, while the Outer ring of galaxies traveling the fastest, in fact, approaching that of the speed of light. As a body's velocity increases - our universe is speeding up, so its mass will increase, and therefore, the gravitational pull will also increase. Eventually (though it is assumed time does not exist) at the outer reaches of the universe, all three rings (simplified universe) will be drawn together and when this happens, as the theory ...

A murdered princess. A royal wedding and peace in the Empire hanging in the balance. A detective will be called out of retirement to solve the case before it is too late. As bodies start to pile up, and a fragile peace looming over the Empire, it’s a race against time to solve the murder before a wedding that can’t be stopped takes place.

A dozen recent Liaden Universe short works are added to the collection in the third volume of A Liaden Universe Constellation. Ranging from comic to cosmic, only one of these works was first published before 2011. These welcome new additions bring the collected Constellation of Lee and Miller Liaden short stories to forty-five works in three volumes. Here is a vast tapestry of tales of the scouts, artists, traders, priestesses, sleight of hand magicians, and pilots who fill the Liaden Universe with the excitement, action, and romance that fans of the hit series have come to adore.

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.

According to the prevailing scientific paradigm, the universe tends toward randomness; it functions according to laws without purpose, and life is an accident devoid of meaning. Thanks to a new understanding of evolution, as well as recent advances in our understanding of the phenomenon known as emergence, a new cosmic narrative is taking shape: Nature’s simplest “parts” come together to form ever-greater “wholes” in a process that has no end in sight. Bobby Azarian explains the science behind this new view of reality and explores what it means for all of us.

¿Cuáles son los mayores retos con los que se presenta el planeta, cuáles las mayores amenazas, dónde buscar la solución a los descomunales problemas con los que se enfrenta nuestra generación y las futuras? El origen y evolución del universo, la naturaleza del tiempo, la estructura de la materia, el infinito,las estrellas fugitivas, las ondas gravitacionales…Estos son algunos de los grandes temas que Rafael Bachiller aborda en este libro tanto desde un punto de vista científico como desde una perspectiva filosófica y humanista.

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.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

Expelled from the Union Astronautica space fleet and facing charges of grand theft, Jules Truffant agrees to sign up as shuttle pilot aboard the freighter Pride of Cucamonga in exchange for amnesty. After botching Pride's mission to RhoCorenae and upsetting an alien culture in the process, Jules must take part in a voyage across the galaxy to place a probe squarely in the path of a black hole as it plows through an inhabited star system.

The war is over. Hurray! Half the fleet is back in mothballs. But out on the rim of human space, ships are disappearing. Some are merchant ships going about their business. Others are exploration ships on deep space probes. What's happening to them? Captain Rita Nuu Longknife is ready to take the heavy cruiser Exeter to space and see what's out there. She may have a nursery next to the captain's cabin and a two-month-old baby on her hip, but she's taking a warship out there, and nobody better get in her way.

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.
