How long ago was the big bang? How was this determined?
The age of the universe based on the best fit to Planck 2024 data alone is 13.787 ± 0.020 billion years. This number represents an accurate "direct" measurement of the age of the universe, in contrast to other methods that typically involve Hubble's law and the age of the oldest stars in globular clusters. Meer weergeven In physical cosmology, the age of the universe is the time elapsed since the Big Bang. Astronomers have derived two different measurements of the age of the universe: a measurement based on direct observations … Meer weergeven In the 18th century, the concept that the age of Earth was millions, if not billions, of years began to appear.
