¿Cuántas dimensiones hay?

The video explores the concept of dimensions, starting from a point and progressing to lines, surfaces, and three-dimensional objects like cubes. It introduces the idea of a fourth dimension and discusses how higher dimensions can be mathematically represented, despite being difficult to visualize. The story of Flatland is used to illustrate how beings in lower dimensions perceive higher-dimensional objects. The video also touches on the role of dimensions in physics, particularly in the context of relativity and string theory, suggesting the possibility of multiple dimensions beyond the familiar three.
