An international team of scientists has made significant strides in understanding the large-scale structure of the Universe by identifying critical gravitational regions known as 'basins of attraction.'

Among their findings, the Sloan Great Wall has emerged as the largest basin of attraction, spanning approximately half a billion cubic light years, which is more than twice the size of the previously recognized Shapley basin.

The research indicates that our Milky Way galaxy is part of this larger Shapley basin of attraction, which encompasses a greater area than the previously identified Laniakea Supercluster.

To achieve these insights, the researchers utilized Cosmicflows-4 (CF4) data alongside a Hamiltonian Monte Carlo algorithm to map the Universe's structure up to about a billion light years.

This study is grounded in the Lambda Cold Dark Matter (LCDM) cosmological model, which explains the evolution of the Universe's structures stemming from early quantum fluctuations.

Overall, this research enhances our understanding of the gravitational forces that shape cosmic flows and large-scale formations within the Universe.

The project was led by Dr. Valade, under the guidance of Professors Yehuda Hoffman and Noam Libeskind, with contributions from other notable scientists.

The findings from this study could refine current cosmological models and significantly improve our knowledge of dark matter distribution and cosmic expansion.
