According to a report by the Physicist Organization Network on February 6th, scientists from the Max Planck Institute in Germany have discovered the largest structure in the universe to date and named it "Quipu" after the Inca knotting system. Chipp "is a type of superstructure with a total mass of 200 trillion times that of the Sun and a length exceeding 1.3 billion light-years. A superstructure is a super large structure that includes galaxy clusters and superclusters. In the latest research, scientists have discovered a total of 5 superstructures, with "Chip" being the largest and breaking the record for the largest known structure in the universe. The grand structure of "Chip" will inevitably have a huge impact on its surrounding environment. Therefore, in-depth exploration of "Chip" and its "brothers" will help people better understand the evolution process of galaxies, further improve cosmological models, and enhance the accuracy and precision of cosmological measurements. The research team used X-ray galaxy clusters to identify and analyze these superstructures. The X-ray galaxy cluster encompasses thousands of galaxies and a large amount of hot gas that emits X-rays. These X-rays are crucial for drawing the superstructure mass map. Research has found that these 5 superstructures cover 45% of galaxy clusters, 30% of galaxies, and 25% of matter in the universe. The research team stated that in order to accurately determine cosmological parameters, they need to understand the impact of local large-scale structures in the universe on measurements. Superstructures such as' Chip 'are so massive that they leave a unique imprint in cosmological observations. For example, these superstructures will leave imprints in the "afterglow" of the Big Bang - the cosmic microwave background (CMB). Theoretical evidence suggests that the gravitational pull of these superstructures can cause fluctuations in CMBs, thereby disrupting our understanding of CMBs and the Big Bang. These superstructures also affect the measurement of the Hubble constant, which is a fundamental parameter in cosmology that describes the rate of expansion of the universe. When galaxies separate due to expansion, there is also local motion - flow motion. And the enormous mass of these superstructures can affect the flow motion, thereby distorting the measurement of the Hubble constant. (New Society)
