In scientific articles on the birth and development of different kinds of universes are usually not discussed the question of where all these universes are, how they co-exist or can interact with each other. Authors of scientific papers concentrate mainly on the properties of hypothetical worlds admissible.

Authors of scientific papers concentrate mainly on the properties of hypothetical worlds admissible. Perhaps the different universes are enormous distances from one another, many times greater than the apparent size of our universe.
Scientists believe the whole world, which emerged after the Big Bang, many times greater than the part that we can see in telescopes. It is only 1028 cm, while the whole universe has to date size 101 000 000 000 000 cm due to inflation and the subsequent expansion of the Big Bang. Here’s to such great distances, perhaps, are characterized by the properties of the universe. This view has found a scientific basis at the end of XX century through the work of Linde AG, dedicated to chaotic inflation.
There is another approach to the question of the relative positions of different worlds, consistent with the classical theory of general relativity of Einstein. Following this view, different universes are within each other and more “major” just encompass the universe of “smaller” as a big doll embraces many more smaller ones. Thus, as in our universe there are many of us isolated from each other worlds, and our universe is part of the enveloping its other universes.
In this case, perhaps our universe – it is just a brief flash and a small quantum fluctuation in some other universe. According to Einstein’s general relativity almost everything is relative, and that lasts us for billions of years, for another observer may result in microseconds. Although this situation is unclear even how to compare the second and meters of different worlds. After all, if our world is atoms and the electron oscillations, it is where our life is a moment, maybe it’s different. And it has no atoms or protons and electrons.
Developed in recent years, multi-dimensional generalization of Einstein’s general relativity offers another opportunity for the coexistence of different universes: they may be located in different dimensions of a multidimensional space of the enveloping them. The idea that our four-dimensional world is included in the world of higher dimensions, was proposed by Russian scientists VA Rubakov and ME Shaposhnikov in 1983, and today it is actively growing, including in the form of the model of “brane world”. In other words, a certain four-dimensional surface in a multidimensional space.
Unfortunately, to give a full and comprehensive answer to the question, where are all these universes, science can not yet, as to explain what it was before, when due to quantum fluctuations arose in our world.
