The Universe

The Universe is everything that exists, including all matter, energy and space. This includes all the galaxies, stars, planets and other celestial bodies we can observe, and the vast spaces between them. The study of the universe, known as cosmology, attempts to understand the origin, structure and evolution of the universe. The main research areas of cosmology include the Big Bang theory, which explains the beginning of the universe, dark matter and dark energy, which make up most of the mass and energy of the universe, and the large-scale structure of the universe. Including the formation and distribution of galaxies and galaxy clusters. Cosmology also includes the search for extra solar planets, the study of gravitational waves, and the quest to understand the fundamental laws of physics that govern the behavior of the universe. The universe is vast and complex, and exploring it continues to bring new discoveries and insights into the nature of our existence.
