宇宙可能不是想象的那么“匀称”

Core Findings - An international research team has published a review article in "Modern Physics Reviews," revealing that the universe may not be as uniform as previously thought, suggesting it could be "skewed" like a balloon that has been pressed on one side [1][3]. Group 1: Theoretical Implications - The discovery challenges the widely accepted "standard cosmological model," which is based on the belief that the universe should appear similar in all directions and locations, akin to a perfectly uniform cake batter [3]. - Scientists have identified a contradiction known as the "cosmic dipole anomaly," which relates to the slight temperature variations in the cosmic microwave background radiation, a remnant from the Big Bang [3][4]. Group 2: Observational Evidence - Observations of distant galaxies have shown a "skewed" distribution that does not align with the expected patterns based on the temperature variations of the cosmic microwave background, indicating a significant discrepancy [4]. - The consistency of results from various instruments, including ground-based radio telescopes and space satellites, strengthens the validity of these findings and reduces the likelihood of instrument error [4]. Group 3: Future Research Directions - Upcoming projects, such as the Euclid satellite and the Vera C. Rubin Observatory, are expected to provide clearer "cosmic panoramas," which may help resolve whether the universe is a regular sphere or has a more complex shape that is not yet understood [4].
