Abstract
This text proposes that from Einstein’s relativity, it is possible to build a model of the universe in which its origin is explained by only two parameters. The universe would be part of an infinite Cosmos-Multiverse in which the universes in accelerated expansion are produced in gravitational networks of universes from black holes that make up these networks. So, we exist inside a gravitational network of universes and black holes.
From the concept of gravitational networks, it is possible to infer three theorems that predict the behavior of black holes in these networks. If the model proposed here is correct, then these theorems would be the three theorems of cosmology. Furthermore, the model of gravitational networks helps to do explain what the area of great attractor of local universe is.
