Five Great Enigmas of Earth | Explore Universe

With our advanced technology – with which we look at the Earth in small details hundreds of kilometres away, we go right to the moon to study it on the spot, measure infinitesimal things of small, colossal times, large – the hope to uncover his secrets. And if many of our hopes of knowing it has been fulfilled – which entitles us to hope and to continue to explore – there are still many things that, even in the 21st century, escape our understanding and remain stones in science, so advanced as they are today. Here are 5 of the “enigmas” of the Earth – unexplained features, completely unsolved aspects, for which we have, for the time being, only assumptions, not certainties.

The earth was formed 4.54 billion years ago, according to the calculations of scientists, who came to this conclusion by analyzing the oldest terrestrial rocks they could find, as well as the oldest meteorites fallen on Earth (starting from the idea that Earth and meteorites formed at the same time when the Solar System was formed by aggregating solid matter around the Sun.) Since then, the planet itself – its internal structure, its atmosphere and its most striking feature, life – as well as the heavenly bodies in her orbit, have gone through countless changes. And some aspects of this evolution have remained unknown to us today.
