New Test Proposed for the Anthropic Principle in Cosmology

A new study by physicists Nemanja Kaloper and Alexander Westphal proposes a method to test the Anthropic Principle, which suggests the universe is fine-tuned for life. The researchers aim to validate this principle by examining cosmic inflation, dark matter, and axions. They suggest that if future observations, such as those from the LiteBIRD satellite or black hole studies, confirm the presence of ultralight axions as dark matter, it would support the Anthropic Principle. Conversely, if axions are not found to be dark matter, it could challenge the principle's validity.
