Importantly, the proposed model does not violate any known laws of physics and may help reconcile the conflicting measurements of the universe's growth.

The Hubble tension stems from conflicting measurements of the universe's expansion rate, derived from two methods: observations of distant supernovae and relic radiation from the Big Bang.

Their findings suggest that the universe could complete one rotation every 500 billion years, a duration that is too slow for easy detection but could significantly influence space expansion over time.

Current models of the universe suggest it expands uniformly in all directions, yet they fail to account for discrepancies in measurements of its expansion rate.

A groundbreaking study led by researchers from the University of Hawai'i, including István Szapudi, proposes that the universe may be rotating very slowly, offering a potential solution to the ongoing 'Hubble tension' in astronomy.

This slow cosmic spin indicates that the universe is still in the early stages of its rotation process, which could take trillions of years to complete a full spin.

The researchers indicate that the effects of this proposed rotation could explain the discrepancies in Hubble constant measurements, becoming more pronounced at greater distances.

The study also suggests that this rotation does not require information to travel faster than the speed of light, thus avoiding potential time travel paradoxes.

This innovative model incorporates a slight rotation into the universe's standard expansion rules, surprisingly resolving the Hubble tension without contradicting existing astronomical data.

Understanding the Hubble constant is crucial for determining the universe's age, size, and the influence of dark energy, which are foundational elements of the Standard Model of Cosmology.

The concept of a rotating universe has been explored previously, particularly to explain why galaxies tend to rotate in one predominant direction.

Looking ahead, the researchers plan to develop a full computer model to further explore the implications of this slow cosmic spin and identify observable signs of it.
