Description

INSTANT NEW YORK TIMES BESTSELLER 

“Provocative and thrilling ... Loeb asks us to think big and to expect the unexpected.”
—Alan Lightman, New York Times bestselling author of Einstein’s Dreams and Searching for Stars on an Island in Maine


Harvard’s top astronomer lays out his controversial theory that our solar system was recently visited by advanced alien technology from a distant star.

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.
 
In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems.

Reviews

  • Interesting but eclectic

    This book combines some high level (not detailed nor numeric) information about Oumuamua that makes a pretty convincing case that the case for it being a lost extraterrestrial solar sail is actually more convincing than the alternatives. However, it’s mixed in with a great deal of personal feelings and anecdotes, some relevant, some hard to connect. The overall result is what might have been a very punchy long-form magazine article becomes a rather meandering book. I think the message is in there, and it is convincing, but it doesn’t really come together as a compelling read.
  • Amazing

    Great mix of personal memoir and insights into the search for extraterrestrial life. You learn a lot about the field of cosmology, astronomy, and physics too. Loeb does a good job of explaining concepts while also leaving it open for further reading if you choose to. As a biology major I really enjoyed it.
  • This guy is a physicist ?

    In the opening pages the author refers to “light years” as a reference to time. An unforgivable faux pas for a scientist. Of course, “light year” is a measure of distance, not time.
