O knihe
Modern geologists and geophysicists accept that the age of the Earth is around 4.54 billion years. This age has been determined by radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples. Following the scientific revolution and the development of radiometric age dating, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old.The oldest such minerals analysed to date - small crystals of zircon from the Jack Hills of Western Australia - are at least 4.404 billion years old.Comparing the mass and luminosity of the Sun to the multitudes of other stars, it appears that the solar system cannot be much older than those rocks.
