Briefings

A new University of Ottawa study presents a cosmological model where the universe is 26.7 billion years old and requires no dark matter or dark energy. This 'CCC+TL Cosmology' passed key Big Bang Nucleosynthesis tests, challenging the standard model. The research is published in the journal Universe.

Key points

• The universe is estimated to be 26.7 billion years old under this new model.
• The model requires zero dark matter and zero dark energy to explain observations.

Context

This research challenges the standard Big Bang model by proposing an alternative where the universe's age and composition differ significantly from current cosmological consensus.

Limitations

The study relies on Big Bang Nucleosynthesis consistency tests; results are preliminary and subject to further validation. Specific observational data limitations are not detailed in the provided evidence.
