These are the things that researchers done to guess the age of Earth

News24xx.com - Researchers estimate the Earth's age is reaching 4.54 billion years with an error margin of 50 billion years. By comparison, the Milky Way galaxy where the solar system is about 13.2 billion years old or three times older than the age of the Earth itself, and for the age of the universe itself is estimated to be 13.8 billion years old.

This figure is derived from the results of combining research in Earth and space. Efforts to research the age of the Earth itself have been going on since 400 years ago. However, efforts to measure the age of the Earth are not easy. It was only in 1953 that researchers succeeded in concluding the age of the Earth at 4.54 billion that year.

Previously, they had tried to determine the age of the Earth from changes in sea level, salt water levels, and by measuring the temperature from the calculation of the time needed by the Earth or the Sun to cool down. But with existing technology, this measurement method turned out to be suitable, because the change in sea level turns out to be a process that is constantly changing rather than occurring gradually over many years.

But research on rock has its own difficulties, because, the tectonic plates of the Earth continue to move. This makes the rock constantly renewed which made the first rock is almost difficult to find, because they have been recycled, melted, and formed into new rocks.

When they tried to observe the Earth's rock layers, there was another obstacle called Great Unconformity. Experts find Earth's rock layers such as the Grand Canyon.
