Unveiling the Mystery: The Scarcity of Milky Way-like Galaxies in Our Vicinity

Researchers have used supercomputer simulations to understand why there are few disk galaxies like the Milky Way in the supergalactic plane (SGP). The simulations showed that inside the SGP, galaxies interact and merge more frequently, transforming spirals into ellipticals. Outside the SGP, galaxies interact less, allowing disk galaxies to retain their form. The results align with observations and support the Lambda Cold Dark Matter (CDM) model, which suggests that the distribution of galaxies in relation to the SGP arises naturally within the standard model of galaxy formation and evolution.
