'A JOY IN CONJECTURE AND AN OMNIVOROUS SPIRIT OF INQUIRY. . . CARL SAGAN WOULD HAVE LIKED THIS BOOK' The Times

In 2017, Avi Loeb, Chair of Harvard's Astronomy Department, went public with a theory that shook the scientific community - our solar system has been visited by advanced alien technology. His provocative and persuasive argument (and internationally bestselling book Extraterrestrial) has opened thousands of minds to the existence of intelligent life beyond Earth. This book tackles the huge question of what happens next?



Combining cutting-edge science, physics, and philosophy, Loeb takes us on a mind-bending journey through the furthest reaches of science, space-time, and the human imagination. Interstellar is an eye-opening, necessary look at our future that proves, once again, that scientific curiosity offers the key to our survival.

'Loeb is surely correct. . . scientists studying the vastness of the cosmos should entertain risky ideas more often, for the universe is undoubtedly more wild and unexpected than any extremes conjured by the human imagination' Economist
