No existe una "Cuarta" dimensión

The video tutorial explores the concept of dimensions, explaining that while we live in three spatial dimensions and one temporal dimension, these dimensions are indistinguishable from one another. The tutorial further discusses how different types of dimensions can be identified, using the analogy of cups of water and oil. It also explores the idea of higher dimensions, such as those proposed in string theory, and briefly touches on the possibility of multiple temporal dimensions.

In the context of string theory, how many spatial dimensions are proposed?

What challenges does the speaker mention regarding the visualization of higher dimensions?
