The Standard Model is a quantum field theory, which means it uses the principles of quantum mechanics to describe the behaviour of matter and energy at the atomic and subatomic levels.
- The Standard Model is based on two fundamental theories:
- Quantum mechanics describes the physical properties of nature as interactions between fields of energy at the scale of atoms and subatomic particles. It is the foundation of all quantum physics.
- Special relativity is a theory of space and time developed by Albert Einstein in 1905. It states that:
- The laws of physics are invariant (i.e., identical) in all inertial frames of reference.
- The speed of light in a vacuum is the same for all observers, regardless of the motion of the light source or observer.
