Particle Physics and Cosmology

The photon is a force carrier, not a fundamental particle.

The strong nuclear force is responsible for holding atomic nuclei together.

The W and Z bosons are responsible for mediating the weak nuclear force.

The photon is responsible for mediating the electromagnetic force.

The graviton is the hypothetical particle that is responsible for mediating the gravitational force.

Quantum Mechanics is the theory that describes the behavior of elementary particles and their interactions.

General Relativity is the theory that describes the behavior of objects in motion and the relationship between space and time.

Special Relativity is the theory that describes the behavior of objects moving at very high speeds.

String Theory is the theory that attempts to unify all of the fundamental forces of nature into a single theory.

A supercluster is the largest structure in the universe that is held together by gravity.

The Big Bang Theory is the theory that describes the origin and evolution of the universe.

The cosmic microwave background radiation is thought to be the leftover radiation from the Big Bang.

Dark energy is thought to be responsible for the accelerated expansion of the universe.

Dark matter is thought to be responsible for the formation of galaxies and other structures in the universe.

Gravitational waves are ripples in spacetime that are produced by the acceleration of massive objects.
