In this fascinating foray into the centuries-old relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and writer-researcher Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. "The overlap is strong, and the knowledge flows in both directions," say the authors, because astrophysicists and military planners care about many of the same things: multi-spectral detection, ranging, tracking, imaging, high ground, nuclear fusion, and access to space. Tyson and Lang call it a "curiously complicit" alliance.

Climate change has been a perplexing problem for years. Casey's research into the Sun's activity, which began almost a decade ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next 30 years or more. This new cold climate will dramatically impact the world's citizens.

Earth barely survived the 21st century. Now, in the 22nd, after unifying Earth, the UN controls all human colonies scattered through the galaxy by means of wormholes, warpdrive ships, and ruthless operatives. Operatives working to strengthen the UN. Or destroy it.

The timeline of the book is a four-city lecture tour the author organized for Hawking in the early 1990s (Portland, Eugene, Seattle, and Vancouver, BC). Hawking's powerful meetings with students with disabilities, officially collateral events, were remarkable. However, the greater significance of these stories of the road is better appreciated in the context of the central narrative question of the book: the nature of the universe and our place/role in it.
