A key concept in special relativity is that time and space are not independent but depend on the relative motion state of the observer. This also includes the idea that relative velocity affects how time and distances between objects are measured. Later, in 1915, Einstein developed general relativity to extend the theory to include the effects of gravity, showing that matter or energy can determine the geometry of spacetime, affecting the motion of bodies and systems in curved spacetime. Additionally, the spacetime structure imposes on matter to position and behave according to its curvature. Then, we examined Einstein's equation and Schwarzschild's solution, which predicted the existence of black holes due to uncertainties in these solutions. We then conducted a thermodynamic study of the Schwarzschild black hole based on classical laws of thermodynamics, calculating some thermodynamic quantities of the black hole, and studying the variations of these quantities in relation to each other by plotting, analyzing, and interpreting the data.
