Astrophysics is a branch of physics that deals with the study of the universe, its celestial objects, and their physical properties.

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Fermi–Dirac statistics, named after physicists Enrico Fermi and Paul Dirac, is a statistical model that describes the behavior of particles with half-integer spin, such as electrons.

Gravity is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another.

Kelvin is a unit of temperature widely used in the scientific field.

Kinetic energy is the energy an object possesses due to its motion.

Neutrons are subatomic particles that are found in the nucleus of an atom.

The Pauli exclusion principle is a fundamental concept in quantum mechanics that states that no two identical fermions can occupy the same quantum state simultaneously.
