[ www.TheTTAcademy.com ] In time travel theory, there is an unknown aspect of the grandfather paradox. If a person does anything that will affect the future, some force in nature will stop them. In The Time Travelers Academy, this force comes within a hair's breadth of destroying humanity when a comet brings a new and unstoppable plague to Earth. The President makes a choice that will either save Earth's inhabitants or annihilate them. At a secret military academy, ten cadets are selected to travel to the future of Earth's sister planet, in the hope that planet has found a cure for the plague. The mission's leader, John Richards, knows that past time travel risks encountering time eliminators: entities that will absorb him and his crew out of existence before their actions can literally reset the universal timeline. But when Richards learns that his fiance was killed in a contract hit, he's determined to go back in time and prevent her death, even if it risks the destruction of the current Earth.

He believes in science, but only magic can help his mom. Twelve-year-old Finn is used to people in his family disappearing. His twin sister, Faith, drowned when they were three years old. A few months ago, his mom abandoned him and his dad with no explanation. Finn clings to the concrete facts in his physics books—and to his best friend, Gabi—to ward off his sadness. But then his grandmother tells him a secret: the women in their family are Travelers, able to move back and forth in time. Finn's mom is trapped somewhere in the timeline, and she's left Finn a portal to find her. But to succeed, he'll have to put his trust in something bigger than logic. "This is an incredible book, no matter which time universe you're in. I couldn't put it down. One of my favorite debut novels of the year."—Erin Entrada Kelly, New York Times bestselling author and 2018 Newbery Medal winner

When physicist Michael Shelborne mysteriously vanishes, his son Shel discovers that he had constructed a time travel device. Fearing his father may be stranded in time—or worse—Shel enlists the aid of linguist Dave MacElroy to accompany him on the rescue mission. Their journey through history takes them from the enlightenment of Renaissance Italy through the American Wild West to the civil-right upheavals of the 20th century.

The story of physicists' quest to answer a mind-boggling question: How can we travel through time? Since H. G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics. Some images in the ebook are not displayed owing to permissions issues.
