CPT Symmetry
CPT symmetry is a fundamental principle in physics stating that the laws governing particles should remain unchanged when three transformations are applied: charge conjugation (C), which replaces particles with their antiparticles; parity transformation (P), which flips spatial coordinates; and time reversal (T), which reverses the direction of time. In essence, it implies that the universe should behave the same way if you swapped particles with antiparticles, flipped all directions, and turned time backwards. This concept is vital for understanding the behavior of matter and antimatter, and it plays a crucial role in particle physics and cosmology.

CPT symmetry is a fundamental principle in physics that combines three transformations: Charge (C) reversal, which changes particles into their antiparticles; Parity (P) reversal, which flips spatial coordinates, like a mirror image; and Time (T) reversal, which reverses the direction of time. Together, these transformations imply that the laws of physics should remain the same even when these changes are applied. If an experiment looks the same with all C, P, and T transformations, it reinforces the idea that the underlying physics is consistent and universal, suggesting a deep symmetry in nature.
