IN SHORT Gravitational singularity: region of spacetime where the laws of physics become imprecise. Contains mathematical limits according to the theory of Einstein. References to Penrose and Hawking theorems regarding black holes. Singularities are points where certain physical parameters reach infinity. The naked singularity implies that the physical laws break down. Interest of cosmology to … Read more
IN BRIEF Definition: A thought experiment is a hypothetical method used to explore complex concepts in theoretical physics. Steps: Includes the formulation of hypotheses, the description of imaginary situations, and the analysis of results. Utility: Allows for the clarification of theories, illustrates physical principles, and challenges preconceived ideas. Famous examples: Include Galileo’s experiments on free … Read more
