The article discusses the Unruh effect, a concept from quantum field theory in curved space-time. The author, a theoretical physicist, reflects on their fascination with space-time and the challenge of explaining it in a way that is intuitive without resorting to equations. They describe their experience of revisiting the mathematical framework for particle physics, quantum field theory, and its connection to relativistic notions of space-time. The author explains that quantum field theory allows for the simultaneous consideration of quantum mechanics and special relativity, and that it replaces the concept of a particle with a notion of a field acting on the vacuum. They also mention the Unruh effect, which states that an accelerating observer will observe the presence of particles where a non-accelerating observer sees none. The article concludes with the author's reflection on the importance of revisiting and reexamining one's understanding of physics. [Extracted from the article]
