What If We Were Not Alone?
For centuries, humans have looked toward the stars and wondered whether someone else might be looking back.
In Contact, renowned astronomer and science communicator Carl Sagan imagines what happens when that question finally receives an answer.
Dr. Ellie Arroway is a brilliant scientist who has devoted her career to searching for evidence of intelligent life beyond Earth. When a mysterious signal is detected from many light-years away, the discovery sets off an extraordinary international effort to determine who sent it, what it means, and what humanity should do about it.
But discovering an extraterrestrial signal is only the beginning.
As scientists work to decipher the message, humanity is forced to confront questions that go far beyond astronomy. What would contact with an advanced civilization mean for science, religion, politics, and the future of our species? And can humanity come together when confronted with the greatest discovery in history?
Science Fiction Grounded in Real Science
Written by one of the world’s most celebrated astronomers, Contact blends scientific concepts with a gripping fictional story. Sagan explores astronomy, mathematics, physics, the search for extraterrestrial intelligence, and the philosophical questions that arise when we consider humanity’s place in the universe.
The result is a science fiction classic that is as much about how we think and what we believe as it is about aliens and distant worlds.
