This book is an overview of both the history of aliens and UFOs, as well as a review of hidden aerospace and propulsive technologies. Where did these technologies come from? And how have they developed in the intervening years? Also, I try to answer some questions of how likely some of these claims are - because some things having to do with UFOs and aliens are much more documented than others. There are also many alien-related and secret programs that most of you listeners may have never heard of. The most interesting ones are summarized here.

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

For any task you might want to do, there's a right way, a wrong way, and a way so monumentally complex, excessive, and inadvisable that no one would ever try it.

At first, only a few things are known about the celestial object that astronomers dub Rama. It is huge, weighing more than ten trillion tons. And it is hurtling through the solar system at inconceivable speed. Then a space probe confirms the unthinkable: Rama is no natural object. It is, incredibly, an interstellar spacecraft. Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence.

In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

I didn't believe in time travel or teleportation until it happened to me. I'm Bruce Gernon, and I flew through the heart of the Bermuda Triangle before I'd even heard the term. Skeptics have dismissed the Triangle as a nonmystery, but they weren't in my airplane when the fog surrounded my craft and I leapt ahead 100 miles. I documented what happened and memorized every detail of that flight. Now, I'm ready to explain that there is no Bermuda Triangle!
