the current estimate for the age of the universe is approximately 13.8 billion years. This age is derived from observations of the cosmic microwave background radiation, the redshift of distant galaxies, and other data obtained from various astronomical measurements. However, please note that scientific knowledge is constantly advancing, and newer measurements and discoveries may have refined this estimate. It's always a good idea to consult the latest scientific sources for the most up-to-date information on the age of the universe.
