Layers in glaciers show a history much longer than 10,000 years, and radiometric dating places the formation of the Earth at 4.5 billion years. Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to 13.7 billion years.
Age of the universe. In cosmology, the age of the universe is the amount of time since the Big Bang. The best measurement of the age of the Universe is 13.8 billion years (specifically, 13.798Â±0.037 billion years). The most recent and most accurate measurements were made by the Planck spacecraft. These measurements were made using the cosmic microwave background radiation and the expansion of the Universe.
