Las CUATRO INTERACCIONES FUNDAMENTALES

The video explores the four fundamental interactions: gravitational, electromagnetic, weak, and strong. It discusses their properties, roles in the universe, and how they form the basis of the Standard Model. The video also highlights the limitations of current theories, such as the Standard Model's inability to include gravity, and the ongoing search for a unified theory, including string theory.
