Radiometric dating indicates that the earth is approximately how old

The Solar System was formed around 4.6 billion years ago, out of the collapse of a dense cloud composed of dusts and gases.Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System’s origins.In an event often referred to as the "Big Bang," the universe arose in a relatively brief moment in time and matter was flung outward from this central origin.Since this beginning, this vast amount of matter has been hurling through space, undergoing a number of many changes as it traverses the cosmos. This age has been determined with the radioactive dating technique.The precise decay rate of radioactive elements is used as a clock: the number of daughter products in one rock indicates its age.

If you're behind a web filter, please make sure that the domains *.and *.are unblocked.The oldest meteorites ever dated in the Solar System are 4,56 billion years old, the oldest minerals on Earth are 4,4 billion years old, and the oldest rocks on Earth are 4 billion years old.These ages are very consistent because the meteorites had to form before the accretion of our planet, and the Earth had to cool down before the first minerals could crystallise.Of course, that error estimate is complete nonsense.It refers to one specific source of error – the uncertainty in the measurement of the amounts of various atoms used in the analysis.
