Extraterrestrial: The First Sign of Intelligent Life Beyond Earth

If you've ever found yourself wondering about life beyond the earth, if there really are aliens somewhere out there in the vastness of space, then this is the book for you. At the end of 2017, astronomers at the observatory on Mauna Kea glimpsed an object moving through our inner solar system so quickly that it could only have come from another star. In this book, Harvard astronomer Avi Loeb demonstrates that it could not have been an asteroid, leaving only one conceivable explanation: the object was a piece of advanced technology belonging to an alien civilization. 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.
