Do UFOs come from the future?

In this book, the author argues for a revolutionary and fascinating hypothesis: that of time travel. UFOs are not extraterrestrials, but our own descendants. In a way, humanity would be visited by itself. This would explain the historical permanence of their appearances since Greco-Roman antiquity, the sacred principle of their non-intervention in the unfolding of human history, the instant materialization and disappearance of their vehicles, their humanoid appearance and their warning against a possible atomic self-destruction of mankind…

To develop this theory, the author reviews over 3,000 years of history of unexplained aerial phenomena, and draws on the most important scientific theories, including general relativity, quantum physics, the Big Bang and black holes.
