Study Suggests Universe's Slow Rotation May Solve Hubble Tension Mystery
  • A recent study led by researchers from the University of Hawaiʻi at Mānoa, including István Szapudi, suggests that the universe may be rotating very slowly, potentially addressing the ongoing 'Hubble tension' in astronomy.

  • The team developed a mathematical model that incorporates a slight rotation of the universe, which resolves the paradox of differing expansion rates without conflicting with existing measurements.

  • The Hubble tension arises from discrepancies in measuring the universe's expansion rate, with one method relying on supernova observations and another on relic radiation from the Big Bang.

  • Current models of the universe indicate an even expansion but fail to account for the inconsistencies in these measurements.

  • The proposed rotation is estimated to occur once every 500 billion years, making it undetectable yet influential on the expansion of space over time.

  • This slow rotation, while difficult to observe, could significantly impact our understanding of cosmic expansion.

  • Importantly, the proposed model does not violate any known physical laws and may clarify the discrepancies in measurements of the universe's growth.

  • By adding rotation to their model, the researchers have surprisingly resolved the Hubble tension without contradicting existing astronomical data.

  • Future work will focus on developing a comprehensive computer model to identify potential signs of this slow rotation in cosmic observations.

  • The next phase of research will involve creating a full computer model to further explore indicators of this slow rotation.
