Milky Way is embedded in a 'large-scale sheet' of dark matter, which explains motions of nearby galaxies angielski
The algorithm started from regions in the early universe, with a mass distribution based on observations of the cosmic microwave background. With a powerful computer, the model then evolved to reproduce the present-day characteristics of the Local Group, with the mass, position and velocity of the Milky Way and the Andromeda galaxy, and the positions and velocities of 31 galaxies just outside the Local Group. This resulted in the creation of simulations that may be considered “virtual twins” of our cosmic environment.
