There is No Fourth Dimension

The video tutorial explores the concept of dimensions, explaining that while we live in three spatial dimensions and one time dimension, these dimensions are indistinguishable from one another. Using an analogy of water and oil, the video illustrates how different types of dimensions can be identified. It further delves into the possibility of additional spatial and time dimensions, as suggested by string theory. The tutorial concludes by encouraging viewers to visualize higher dimensions through resources like the book 'Flatland' or solving a 4D Rubik's cube.
