The large-scale structure of the universe refers to the organization and distribution of matter on cosmic scales, characterized by a vast network of galaxies, galaxy clusters, and dark matter forming a cosmic web. This structure is shaped by gravitational interactions and the initial conditions set by the Big Bang, and is studied through observations of galaxy distributions and cosmic microwave background radiation.

Galaxy clusters are the largest gravitationally bound structures in the universe, consisting of hundreds to thousands of galaxies along with dark matter and hot gas. They are crucial for understanding the large-scale structure of the cosmos and provide insights into the distribution and behavior of dark matter and the evolution of galaxies.

Dark matter is a form of matter that does not emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects on visible matter. It is believed to constitute approximately 27% of the universe, influencing the structure and evolution of galaxies and galaxy clusters.

The Cosmic Web is the large-scale structure of the universe, consisting of interconnected filaments of galaxies and dark matter that form a vast network. It is the result of gravitational forces shaping matter over billions of years, revealing the distribution of matter and the underlying structure of the cosmos.

Gravitational interactions are fundamental forces of nature that govern the attraction between masses, influencing the structure and dynamics of the universe from galaxies to everyday objects on Earth. These interactions are described by Einstein's General Theory of Relativity, which explains gravity as the curvature of spacetime caused by mass and energy.

Cosmic microwave background radiation is the thermal remnant from the Big Bang, providing a snapshot of the universe when it was just 380,000 years old. It is a nearly uniform background of microwave radiation that fills the universe and is a critical piece of evidence for the Big Bang theory, offering insights into the early conditions and subsequent evolution of the cosmos.
