Sinossi

This book contains three titles: 
- Celestial Conundrums: Dark matter, a mysterious and invisible substance, remains one of the most profound puzzles in modern astrophysics. Despite being undetectable by conventional means, its presence is inferred through its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Comprising roughly 27% of the universe’s total mass-energy content, dark matter far outweighs the ordinary matter that makes up stars, planets, and galaxies. However, scientists have yet to identify its true nature. 
- Cosmic Construction: The concept of interstellar megaprojects has long captured the imagination of visionaries and scientists alike. Initially, these ideas resided in the realm of science fiction, where vast space-faring civilizations would design and build monumental structures to harness the power of stars or travel across galaxies. 
- The Top 5 Most Persuasive Alien Abduction Accounts: For centuries, humanity has looked to the stars with wonder and curiosity, speculating about the existence of life beyond our planet. While astronomers and scientists seek concrete evidence of extraterrestrial life, a different kind of proof has captured the public's imagination: alien abduction accounts. These extraordinary stories, often dismissed as fantasy or delusion, have sparked debates that straddle the line between science, psychology, and the unexplained.
