Cosmology is the scientific study of the origin, evolution, and structure of the universe. Key concepts in cosmology include: The Big Bang Theory: The leading explanation for the universe's origin, suggesting it began as a singularity and has been expanding ever since. Cosmic Microwave Background (CMB): Radiation left over from the early, hot phase of the universe, providing evidence for the Big Bang. Dark Matter: A mysterious form of matter that doesn't emit light but affects the universe's structure and expansion through its gravitational influence. Dark Energy: A form of energy causing the accelerated expansion of the universe. Hubble’s Law: The observation that galaxies are moving away from us, with their velocity proportional to their distance, indicating an expanding universe. Cosmology combines observations from astronomy with theoretical physics to understand the universe’s past, present, and future.
