Science Universe

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.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.

Fleeing the scene of his latest mission, Val Con yos'Phelium finds himself saving the life of ex-mercenary Miri Robertson, a young Tarren on the run from interplanetary assassins. Thrown together by circumstances, Val Con and Miri struggle to elude their enemies and stay alive without slaying each other - or surrendering to the unexpected passion that flares between them.

Pursued by enemies, exiled Liaden clan Korval is settling into a new base on backworld Surebleak. Moving is expensive, as is war, and Korval is strapped for cash.

Dutiful Passage is targeted by Korval's enemies, denied docking at respectable ports, and cheated by those less respectable. Struggling to recuperate from an attack on his life, while managing daughter Padi’s emerging psychic talents, Shan is running out of options - and time.

Ties that bind...Danai Liao-Centrella is many things: Solaris gladiator; proud military commander; successful diplomat. All of those roles pale beneath perhaps the heaviest responsibility of anyone in the Capellan Confederation: To speak the truth to its ruler, Chancellor Daoshen Liao. He is the undeniable dictator of hundreds of worlds. Mighty armies move at his command. Billions of lives hang on his every decision. Against that, she must speak the truth. And the truth is, the war with House Davion must end. Because there is a greater danger looming.

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Pursued across space by the ultra-secret Department of the Interior, hunted by the galaxy-wide Juntavas syndicate, former Agent of Change Val Con yos'Phelium and his ex-soldier lifemate Miri Robertson have commandeered the only spaceship on Vandar and fled, seeking help from Miri's newly discovered kin on Lytaxin. Elsewhere, Clan Korval is in action. Scattered across space by the newly invoked Plan B, certain clan members pursue the search for the long-missing Val Con.

And that girl’s name was Morrighan. Discover the origin story of the Remnant universe, penned by the New York Times-bestselling master storyteller Mary E. Pearson, in this swoon-worthy prequel, a romance for the ages, and a magic that stirs the heart.

Before the days of going toe-to-toe with the Avengers, a younger Loki is desperate to prove himself heroic and capable, while it seems everyone around him suspects him of inevitable villainy and depravity...except for Amora. Asgard's resident sorceress-in-training feels like a kindred spirit - someone who values magic and knowledge, who might even see the best in him. But when Loki and Amora cause the destruction of one of Asgard's most prized possessions, Amora is banished to Earth, where her powers will slowly and excruciatingly fade to nothing.

Take a roller-coaster ride through the vastness of space! In the midst of an exciting adventure, discover the mysteries of physics, science, and the universe along with George and his new friends next door, the scientist Eric and his daughter, Annie, as well as a super-intelligent computer called Cosmos. The computer can take them to the edge of a black hole and back again. Or can it? And who else would like to get their hands on Cosmos?

Scientists in the past few decades have made crucial discoveries about how our cosmos evolved over the past 13.8 billion years. But there remains a critical gap in our knowledge: We still know very little about what happened in the first seconds after the Big Bang. At the Edge of Time focuses on what we have recently learned and are still striving to understand about this most essential and mysterious period of time at the beginning of cosmic history.

A powerful new threat forces the Alliance to abandon Earth. They leave a small force behind, praying it will be enough to protect humanity from enslavement - or worse, extinction.

But Kaori begins to fear that her bond with Shinonome has frayed. He's keeping secrets from her, and they have something to do with his mysterious friend, the story-seller Tamaki. Worse, Kaori finds herself questioning the purpose of the bookstore itself--what if the stories she and her father bring to the spirit realm are doing more harm than good?

Warped Passages is an altogether exhilarating journey that tracks the arc of discovery from early 20th-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature.
