What if the mysteries of the universe could be unlocked by knowledge from another world? In 1985, Zhang XiangQian, a farmer from rural China, had an extraordinary encounter with an advanced extraterrestrial civilization. Abducted at the age of 18, Zhang returned with profound knowledge that challenges the very foundations of modern physics-knowledge that laid the foundation for his United Field Theory. Despite his middle-school education, Zhang's insights offer a fresh perspective on the universe, uniting gravitational, electric, magnetic, and nuclear forces into a single, revolutionary framework. United Field Theory - Extraterrestrial Technology presents groundbreaking concepts that could transform space travel, energy systems, and communication technologies. Zhang's theory bridges the gap between science fiction and cutting-edge physics, exploring the relationships between mass, energy, and light at a level that has never been conceived before. Through meticulous explanation, Zhang XiangQian's work offers readers a glimpse into the future of science and technology, providing innovative ideas that could redefine our understanding of the cosmos. This is more than just a book-it's an invitation to explore the next frontier of human knowledge. Join the conversation and uncover a theory that pushes the boundaries of conventional science.
