Space Universe

The theoretical physicist shares his thoughts on the nature of space and time in this anthology of selections from Princeton University Press. Along with eminent colleagues, Hawking extends theoretical frontiers by speculating on the big questions of modern cosmology.

In the 18th century, the British minister and mathematician Thomas Bayes devised a theorem that allowed him to assign probabilities to events that had never happened before. It languished in obscurity for centuries until computers came along and made it easy to crunch the numbers. Now, as the foundation of big data, Bayes's formula has become a linchpin of the digital economy. But here's where things get interesting: Bayes's theorem can also be used to lay odds on the existence of extraterrestrial intelligence, and on the biggest question of all: how long will humanity survive?

Beset by the angry remnants of the Department of the Interior, challenged at every turn by opportunists on their new homeworld of Surebleak, and somewhat low on funds, Clan Korval desperately needs to reestablish its position as one of the top trading clans in known space. To this end, Master Trader Shan yos'Galan, aboard Korval's premier trade ship, Dutiful Passage, is on a mission to establish new business associations and to build a strong primary route that links well with existing Loops and secondary routes.

This book invites you on a journey through the most misunderstood concept in all of science — the vacuum. From the earliest philosophers terrified of emptiness to the modern physicists who discovered that “nothing” is a swirling ocean of energy and possibility, this is the story of how the void became the foundation of everything. We begin with the ancient debates about ether and the first laboratory vacuums of the Renaissance, then move through Einstein’s curved spacetime, quantum field theory’s restless vacuum, and the mysterious Higgs field that gives matter its mass.

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.

Hypotheses are formed, observations taken, and experiments performed in the search for universal laws that describe all that we see. In this resourceful guide, common and uncommon questions about the universe will be explained in comprehensive but easy-to-understand terms.

Why did Elon Musk feel compelled to send a red Tesla into space? What accounts for the multiple rocket-themed playgrounds constructed after the Russians launched Sputnik?

Engaging and erudite, Gorman recounts her background as a (nonspace) archaeologist and how she became interested in space artifacts.
