Sharipov 1 ...  4 5 6 ... ru    In the new theory, which is called the 3D-brane universe model, there is a special infinite family of 3D-branes (see 3D-branes in thespace-time ). It turns spacetime into a 3D brane foliation. Each brane in this foliation corresponds to a specific instant in the evolution of the universe. Only one of the branes corresponds to the current instant, that is, the instant of the present. It is that very brane that has the prototype in the form of the real three-dimensional physical universe in its current state. The remaining branes correspond to past states of the universe that have ceased to exist, and its future states that have not yet formed. Let us choose at each point of each 3D-brane the vector of unit length perpendicular to the brane and directed towards the future. Such vectors form the vector field of unit normal vectors to the branes.   Each vector field has integral c

The new theory is based on a criticism of the concept of space-time (see Criticism of thespace-time sausage ). In Einstein's theory, the space-time is recognized as a four-dimensional physical continuum, having material existence in its entirety. In the new theory, space-time is just a product of our mind, a mathematical abstraction. It does not accumulate the past in a material form and does not contain the future in a ready-made physically formed form. Otherwise, the space-time of the new theory is very similar to the space-time of Einstein's theory. It is shown on the following picture.   On the picture we see the subdivision of the space-time into the three-dimensional space and the one-dimensional time. The space is depicted in the form of slightly curved two-dimensional surf

(See Criticism of space-time sausage ). It accumulates layer by layer, receiving material from the present, and forms the four-dimensional space-time. The picture shows two layers in the form of two planes. In fact, the layers are not two-dimensional, but three-dimensional and there are not two of them, but infinitely many. They fill the entire four-dimensional space-time. If we do not consider the entire space-time, but limit ourselves to the boundaries of the planet Earth, we will end up with a space-time sausage.  The entire history of planet Earth fits into a space-time sausage.    Stephen King offered an interesting look at the past in his science fiction novella “The Langoliers.” According to Stephen King, the past is not preserved in the space-time

  Criticism of the space-time sausage. Ruslan A. Sharipov 1 2 3 ... ru The concept of space-time arose in the early 20th century in connection with Einstein's theory of relativity. It is a combination of three-dimensional space and one-dimensional time, which had previously been considered separately, into one four-dimensional continuum. We cannot depict a four-dimensional continuum graphically. Therefore we reduce the three-dimensional space to the two-dimensional space and reserve the third dimension for to image the time. As a result we get the following picture. The horizontal planes on the picture symbolize the states of the universe at different instants in time during its evolution. In fact, they are three-dimensional and there are not two of them, but infinitely many. They fill the entire four-dimensional space-time. Instead of considering the entire universe, we can limit ourselves to some part of it. For example, the globe. Then we get the
