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.
Well, this is some exciting news.

Headline suggests that this is an observed fact, rather than the result of a simulation based on a model created by several EU scientists.
Furthermore the article asserts that “The observed motions … can only be properly explained with this “flat” mass distribution.” That premature assertion, based on this paper
www.nature.com/articles/s41550-025-02770-w
will have to stand up in the court of opinion of scientific peers. I hope to see Sabine go after that headline.
