Descripción editorial
The award-winning science writer “packs a lot of learning into a deceptively light and enjoyable read” exploring the contentious history of the black hole (New Scientist).
For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The strange notion of a space-time abyss from which not even light escapes seemed to confound all logic. Now Marcia Bartusiak, author of Einstein’s Unfinished Symphony and The Day We Found the Universe, recounts the frustrating, exhilarating, and at times humorous battles over one of history’s most dazzling ideas.
Bartusiak shows how the black hole helped revive Einstein’s greatest achievement, the general theory of relativity, after decades of languishing in obscurity. Not until astronomers discovered such surprising new phenomena as neutron stars and black holes did the once-sedate universe transform into an Einsteinian cosmos, filled with sources of titanic energy that can be understood only in the light of relativity. Black Hole explains how Albert Einstein, Stephen Hawking, and other leading thinkers completely changed the way we see the universe.
PUBLISHERS WEEKLY
Bartusiak (Archives of the Universe), professor in the Graduate Program in Science Writing at MIT, reveals the story and science of black holes in all their "stark and alien weirdness." Black holes begin, and end, with gravity. The first person to propose this idea was 18th-century English polymath John Michell, who imagined a star so massive that "all light... would be made to return towards it, by its own proper gravity." As Bartusiak relates, the idea remained a curiosity until Einstein proffered his theory of special relativity (1905) and the idea that gravity could bend light and motion. German astronomer Karl Schwarzschild envisioned an "event horizon," the point of no return beyond which nothing could escape a massive star's extreme gravity, but no one believed it could happen. Then Subrahmanyan Chandrasekhar showed how a massive white dwarf star could shrivel to nothing under its own gravity. Bartusiak notes that Einstein and many others rejected the idea, but by the 1960s, observational evidence and computer advances that allowed astronomers to model stellar collapse showed that black holes were real. Bartusiak's lively, accessible writing and insight into the personalities behind the science make her book an entertaining and informative read.
