A futuristic, optimistic, and intellectually stimulating report for space enthusiasts or readers with celestial wanderlust.
Scientific and philosophical testimony on the possibilities of interstellar relocation.
In his third book, Nadis merges space science and technology in an intermittently fascinating exploration of the human quest to mine extraterrestrial lands for habitation. Admittedly “slow to warm to science fiction,” the author eventually came to appreciate the genre’s creative exploration of new worlds and how real-life space programs expound on those same ideas to make them a reality. Nadis discusses the increasing relevancy of human spaceflight and entertainingly details how the possibilities of space travel moved from the conceptions of astronomer Camille Flammarion, German aerospace engineer Wernher von Braun, and author H.G. Wells into the contemporary landscape, in which some believe in the possibility of terraforming Mars. Nadis smoothly weaves in the progressive history of artificial biospheres and space colonization. However impressive these details may read and despite ambitious modern technological advances, however, experts report the effort of “rejuvenating a dead planet and creating of it a new Earth” will remain an enormously costly and risky project fraught with unseen complications. Leading the way in the space tourism business is billionaire Elon Musk, a spaceflight visionary whom Nadis spotlights prominently for his aggressive pursuit of Mars colonization. The author shows how initiatives like his SpaceX international rocket, along with Jeff Bezos’ Blue Origin program and smaller-scaled NASA programs, are collectively remapping the future possibilities of space travel. Noting the ever evolving social acceptance of interplanetary spaceflight, Nadis stresses that what was once considered “fringe thought” has now become a cosmic race very much in the mainstream. Citing journals, exhibits, academic texts, and interviews with space innovators and other experts, the author provides a solid, sometimes wondrous introduction to a field that is just beginning to show signs of promise.

BOOK REVIEW
An enthusiastic appreciation of a spectacular astrophysical entity.
A short, lively account of one of the oddest and most intriguing topics in astrophysics.
Levin, a Guggenheim fellow and professor of physics and astronomy at Barnard College, knows her subject well, but her goal is appreciation as much as education, and there is much to admire in a black hole. Before Einstein, writes the author, scientists believed that the force of gravity influenced the speed of moving objects. They also knew that light always travels at exactly the speed of light. This combination made no sense until 1915, when Einstein explained that gravity is not a force but a curving of space (really, space-time) near a body of matter. The more massive the matter, the greater it curves the space in its vicinity; other bodies that approach appear to bend or change speed when they are merely moving forward through distorted space-time. Einstein’s equations indicated that, above a certain mass, space-time would curve enough to double back on itself and disappear, but this was considered a mathematical curiosity until the 1960s, when objects that did just that began turning up: black holes. Light cannot emerge from a black hole, but it is not invisible. Large holes attract crowds of orbiting stars whose density produces frictional heating and intense radiation. No writer, Levin included, can contain their fascination with the event horizon, the boundary of the black hole where space-time doubles back. Nothing inside the event horizon, matter or radiation, can leave, and anything that enters is lost forever. Time slows near the horizon and then stops. The author’s discussions of the science behind her subject will enlighten those who have read similar books, perhaps the best being Marcia Bartusiak’s Black Hole (2015). Readers coming to black holes for the first time will share Levin’s wonder but may struggle with some of her explanations.

BOOK REVIEW
An oft-ignored but fully convincing argument that “we cannot prevent the next pandemic without creating a healthy world.”
The Covid-19 pandemic is not a one-off catastrophe. An epidemiologist presents a cogent argument for a fundamental refocusing of resources on “the foundational forces that shape health.”
In this passionate and instructive book, Galea, dean of the Boston University School of Public Health, writes that Covid emerged because we have long neglected basic preventative measures. “We invest vast amounts of money in healthcare,” he writes, “but comparatively little in health.” Readers looking to learn how governments (mainly the U.S.) mishandled the pandemic have a flood of books to choose from, but Galea has bigger issues to raise. Better medical care will not stop the next epidemic, he warns. We must structure a world “that is resilient to contagions.” He begins by describing the current state of world health, where progress has been spectacular. Global life expectancy has more than doubled since 1900. Malnutrition, poverty, and child mortality have dropped. However, as the author stresses repeatedly, medical progress contributed far less to the current situation than better food, clean water, hygiene, education, and prosperity. That’s the good news. More problematic is that money is a powerful determinant of health; those who have it live longer. Galea begins the bad news by pointing out the misleading statistic that Covid-19 kills less than 1% of those infected; that applies to young people in good health. For those over 60, it kills 6%, for diabetics, over 7%, and those with heart disease, over 10%. It also kills more Blacks than Whites, more poor than middle-class people, and more people without health insurance. The author is clearly not just interested in Covid. He attacks racism, sexism, and poverty in equal measure, making a plea for compassion toward stigmatized conditions such as obesity and addiction. He consistently urges the U.S. government, which has spared no expense and effort to defeat the pandemic, to do the same for social injustice.
