It seems like a science fiction movie, but a group of researchers is trying to calculate (again) how much is left before reaching a point of no return for the sustenance of the planet as we know it now. Although this time the object of study is more peculiar: the remaining energy on planet Earth.
Scientists from the University of Maryland, Charles University in the Czech Republic and the Chinese Academy of Geological Sciences have just published a research advance in the most recent edition of Nature, where they share an ambitious project, where they all develop a reliable method of calculation to estimate without fear of failure how much energy our planet has left.
Starting from the two main elements that function as fuel for the Earth: that primordial energy left over from the formation of the planet 4.6 billion years ago, and the nuclear energy from the heat produced by natural radioactive decay, the researchers are working on an advanced model that By 2025 it will allow calculating, with a minimum range of failure, the gasoline that remains in the tank.
The most interesting is the method used, since the key point of measurement is the Geoneutrinos, tiny particles by-product of nuclear reactions inside stars, supernovae, black holes, but also produced by radioactive decay in the depths of the Earth.
To be able to track these Geoneutrinos a special facility is required, the size of an office building and buried almost a mile deep. Japan and Italy already have two "radars", while this project is developing it is intended to install another three, distributed between Canada and China.
By 2025 we will have the answers.
