A curiosity-whetting investigation of imagined life beyond our world.
Are we alone in the universe? Two well-known astronomers tackle the possibilities in this tour of exoplanets.
We know of only one planet on which life exists—Earth—but is life an everyday chemical and physical reaction in the universe or a unique fluke? We have a pretty good idea of some of the steps that led to life on Earth and a firm understanding of how it evolved since then. So how does this apply to the types of exoplanets we may encounter? Would life develop there as it did on Earth? How different could it be? Given the complexity and diversity of exoplanets we have found, will the answers be correspondingly complex and diverse? These are some of the questions approached by George Mason University physics and astronomy professors Trefil and Summers (co-authors: Exoplanets, 2018, etc.) in this sober yet enervating examination of possible life scenarios on a variety of exoplanet settings. First, the authors define life, which can be handled as a list (adaptation, growth, homeostasis, metabolism, organization, reproduction, responsiveness), a process (the NASA definition is “a self-sustaining chemical system capable of Darwinian evolution”), or in terms of thermodynamics. The authors then take these definitions and apply them to a variety of possible planets: one with a rocky mantle and a metallic core overlaid with ice; one with an ocean beneath ice; in another, a land-and-water combination, etc. They probe each scenario to imagine how life could have taken shape given the opportunities and constraints. Trefil and Summers try their best to keep the language geared to a lay audience, but they can’t avoid some formulas: “Galileo’s argument rests on the fact that the volume, and hence the mass, of a structure depends on the cube of its dimensions, while the size of the support area depends on the square.” Overall, though, the prose is straightforward, and the authors make the potentialities of exoplanet life intriguingly real. Finally, they consider nonorganic life forms, for instance silicon chemistry replacing carbon-based life forms.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.

Yes: it's high time for a de-romanticized, de-mythified, close-up retelling of the U.S. Space Program's launching—the inside story of those first seven astronauts.
But no: jazzy, jivey, exclamation-pointed, italicized Tom Wolfe "Mr. Overkill" hasn't really got the fight stuff for the job. Admittedly, he covers all the ground. He begins with the competitive, macho world of test pilots from which the astronauts came (thus being grossly overqualified to just sit in a controlled capsule); he follows the choosing of the Seven, the preparations for space flight, the flights themselves, the feelings of the wives; and he presents the breathless press coverage, the sudden celebrity, the glorification. He even throws in some of the technology. But instead of replacing the heroic standard version with the ring of truth, Wolfe merely offers an alternative myth: a surreal, satiric, often cartoony Wolfe-arama that, especially since there isn't a bit of documentation along the way, has one constantly wondering if anything really happened the way Wolfe tells it. His astronauts (referred to as "the brethren" or "The True Brothers") are obsessed with having the "right stuff" that certain blend of guts and smarts that spells pilot success. The Press is a ravenous fool, always referred to as "the eternal Victorian Gent": when Walter Cronkite's voice breaks while reporting a possible astronaut death, "There was the Press the Genteel Gent, coming up with the appropriate emotion. . . live. . . with no prompting whatsoever!" And, most off-puttingly, Wolfe presumes to enter the minds of one and all: he's with near-drowing Gus Grissom ("Cox. . . That face up there!—it's Cox. . . Cox knew how to get people out of here! . . . Cox! . . ."); he's with Betty Grissom angry about not staying at Holiday Inn ("Now. . . they truly owed her"); and, in a crude hatchet-job, he's with John Glenn furious at Al Shepard's being chosen for the first flight, pontificating to the others about their licentious behavior, or holding onto his self-image during his flight ("Oh, yes! I've been here before! And I am immune! I don't get into corners I can't get out of! . . . The Presbyterian Pilot was not about to foul up. His pipeline to dear Lord could not be clearer"). Certainly there's much here that Wolfe is quite right about, much that people will be interested in hearing: the P-R whitewash of Grissom's foul-up, the Life magazine excesses, the inter-astronaut tensions. And, for those who want to give Wolfe the benefit of the doubt throughout, there are emotional reconstructions that are juicily shrill.
But most readers outside the slick urban Wolfe orbit will find credibility fatally undermined by the self-indulgent digressions, the stylistic excesses, and the broadly satiric, anti-All-American stance; and, though The Right Stuff has enough energy, sass, and dirt to attract an audience, it mostly suggests that until Wolfe can put his subject first and his preening writing-persona second, he probably won't be a convincing chronicler of anything much weightier than radical chic.
