‘Event Horizon’ and ‘Singularity’ are terms associated with black holes, phenomena extensively studied in astrophysics and cosmology, related to the structure and evolution of the Universe. ‘String Theory’ is a theoretical framework in physics attempting to describe the fundamental constituents of the universe as tiny vibrating strings, aiming for a unified theory of everything. The ‘Standard Model’ is a theory describing the fundamental particles and forces (excluding gravity) that make up the Universe and how they interact. All these terms belong to the fields of cosmology, astrophysics, and theoretical particle physics, which are dedicated to observing and understanding the fundamental nature and workings of the Universe.
