Degenerate matter is a highly dense state of matter where quantum mechanical effects, particularly the Pauli exclusion principle, dominate the behavior of particles, typically electrons or neutrons. This state occurs in stellar remnants like white dwarfs and neutron stars, where gravitational forces have compressed matter to the point that classical physics no longer adequately describes its properties.

The Pauli Exclusion Principle, formulated by Wolfgang Pauli in 1925, states that no two fermions can occupy the same quantum state simultaneously within a quantum system. This principle is fundamental in explaining the structure of atoms and the behavior of electrons in atoms, leading to the diverse properties of matter.

behavior of particles

Electrons are subatomic particles with a negative electric charge, fundamental to the structure of atoms and the flow of electricity. They play a crucial role in chemical bonding and are key to understanding quantum mechanics and electromagnetic interactions.

electrons

Neutrons are subatomic particles with no electric charge, found in the nucleus of an atom alongside protons. They play a crucial role in the stability of atomic nuclei and are essential for nuclear reactions, including fission and fusion processes.

neutrons

Stellar remnants are the dense, compact objects left behind after a star has exhausted its nuclear fuel and undergone a supernova or similar catastrophic event. Depending on the mass of the progenitor star, these remnants can be white dwarfs, neutron stars, or black holes, each with unique properties and implications for understanding stellar evolution and the dynamics of galaxies.

White dwarfs are the remnants of stars that have exhausted their nuclear fuel and have collapsed into a dense, Earth-sized object composed mostly of electron-degenerate matter. They represent the final evolutionary state of stars not massive enough to become neutron stars or black holes, gradually cooling and fading over billions of years.

Neutron stars are the remnants of massive stars that have undergone supernova explosions, resulting in an incredibly dense object primarily composed of neutrons. They exhibit extreme gravitational and magnetic fields, and their study provides insights into fundamental physics and the behavior of matter under extreme conditions.

Gravitational forces are the attractive forces between masses, which govern the motion of celestial bodies and the structure of the universe. They are described by Newton's law of universal gravitation and further refined by Einstein's general theory of relativity, which accounts for the curvature of spacetime around massive objects.

Classical physics encompasses the principles and theories developed before the advent of quantum mechanics and relativity, primarily focusing on macroscopic phenomena. It includes foundational laws and concepts that describe the motion of bodies, forces, energy, and the properties of matter and waves in a deterministic framework.

classical physics

Everything around us is made of matter, and matter has special things called properties that we can see or feel, like how it looks, feels, or smells. These properties help us tell different things apart, like knowing a rock is hard and an ice cream is cold and sweet.
