Scientists claim the universe is twice as old as believed
Yahoo • • science
Key Points:
- Researchers at the University of Ottawa propose a new cosmological model, CCC+TL, suggesting the universe could be 26.7 billion years old, nearly twice the widely accepted age.
- The model challenges the need for dark matter and dark energy by positing that physical constants vary over time and light loses energy traveling through space, extending the universe's age estimate.
- CCC+TL successfully matches key observations, including the abundance of hydrogen and helium from the Big Bang, galaxy rotation patterns, and the universe's expansion rate without dark energy.
- The model may explain early large galaxies observed by the James Webb Space Telescope by allowing more time for their growth in an older universe.
- While promising, the theory remains outside mainstream consensus and requires further independent verification and testing with future astronomical data.
