Gigantic ‘Bubble of Galaxies’ found stretching across billions of light years
- Scientists studying galaxy movements have discovered signs that our cosmic neighborhood may be part of a much larger system than previously believed.
- Analysis of over 56,000 galaxies by the Cosmicflows group revealed evidence of a galactic basin, Laniākea, possibly ten times larger than its known size.
- New data indicates a 60% chance that Laniākea extends towards the Shapley concentration, a region dense with mass and gravitational force.
- The discovery challenges current views on cosmic structures and suggests that the universe's architecture may need revision to show larger interconnected basins.
- The study implies that cosmic structures began growing more extensively than previously thought and questions the completeness of current cosmic surveys.
- Researcher Ehsan Kourkchi highlighted the challenges posed by the immense cosmic basins and the limitations of current survey tools.
- By analyzing the gravitational effects on galaxy movements, researchers can map the flow of galaxies within superclusters in the local universe.
- The ongoing research aims to understand the universe's interconnected cosmic system and our place within it, potentially linking our galaxy to grander structures.
- The study involves international astronomers like R. Brent Tully, Aurelien Valade, Noam Libeskind, and others, emphasizing the collaborative nature of astronomical research.
- The discovery challenges existing cosmic models, highlighting the vastness of the universe and continuing efforts to expand our knowledge of cosmic evolution.
