New Theory: Warm Cosmic Inflation Explained with Standard Particle Physics

How did the universe begin? A groundbreaking new model suggests that cosmic inflation, the rapid expansion of the early universe, occurred in a warm environment filled with known elementary particles. This theory, published in Physical Review Letters, challenges traditional views of a cold and empty early universe. Scientists propose that the strong force, a fundamental interaction in the Standard Model, played a key role in heating the expanding universe. This model offers a unique advantage: it relies on well-studied particles and forces, making it testable through Earth-based experiments. The research also explores the role of hypothetical axion-like particles and their potential connection to dark matter. Join us as we dive into this fascinating new perspective on the origins of the universe and its implications for particle physics.
