In short, Kolobok is a four-dimensional pizza. Do not ask why.

Not exactly so. The colobok is a projection of a certain four-dimensional object (in analogy with the hypercube it will be a hypercube) onto our three-dimensional world. Pizza is a two-dimensional projection of it. They have a common geometric law: all its points are equally distant from the common center in all dimensions. In two dimensions it is a circle, in three it is a ball, and in four it is a hyperchar. There is no further terminology, but real mathematics does not care about such little things. Have you heard that triple integrals have no physical meaning? Unlike single and double. Here too is the same: there is a law, there are equations, the number of dimensions does not matter. In string theory, the ends and ends coincide with the assumption that the universe is at least eight-dimensional, I think.

There are several string theories, 26 dimensions are required to describe the boson string theory, and only 10 are required for the rest of the theories, with each theory describing space-time with different characteristics. The eight-dimensional theory was made by a German physicist-theorist, the name and date I, unfortunately, do not remember, it was in the last century. His theory may be able to help make a hyper jump.
