STARBORN

Looking for an original focus among the many books describing the universe, a theoretical physicist looks to the stars.

“Stars and planets spurred the invention of mathematics; the Moon, that of the calendar,” writes Trotta, author of The Edge of the Sky. “And could it be that paying attention to the heavens was the secret weapon that gave Homo sapiens supremacy over the Neanderthals fifty thousand years ago?” For millennia, the movements of the constellations, the five “wandering stars” (Mercury, Venus, Mars, Jupiter, and Saturn), the Moon, the Sun, and occasional comets and meteors have held deep significance. They have governed clocks, calendars, seasons, planting, harvests, and holidays and have been the basis of myth and religion. While minor gods inhabited forests and caves, the big ones lived in the sky. All cultures have wondered at the stars. Trotta passes quickly over the big bang and follows no strict chronology, but he pauses regularly to recount events in a fictional culture on a planet where clouds permanently hide the sky. The result is a scattershot collection of chapters describing milestones in the study of stars, from the origin of calendars lost in prehistory to the mysteries of dark energy in this century. Astronomy buffs will find few pearls, but most readers will enjoy expert accounts of clocks throughout history; Newton’s spectacular work; the history of navigation (still entirely dependent on the stars); telescopes, from Galileo’s in 1611 to last year’s James Webb; the dazzling 19th-century discoveries of the enormous quantities and distances of stars; the dawn of computers; and the amazing appeal of astrology. In a grim conclusion, Trotta warns that the stars have long since disappeared from our light-poisoned cities and are imperiled everywhere, as we fill the air with pollution and Earth’s vicinity with space junk, spending billions on sending humans into orbit while billions suffer on Earth.

A largely satisfying miscellany about stars.
