MADRID.- The Earth’s core – a sphere of almost pure iron more than 5,000 kilometers deep that is hotter than the Sun – has slowed down and it is possible that it is rotating in the opposite direction to the surface of the planet , according to a study published today in Nature Geoscience . This slowdown can have global effects, such as shortening the days by a few fractions of a second and influencing the climate and sea level.
The two authors of the paper are Yi Yang and Xiaodong Song, from Peking University’s Institute of Theoretical and Applied Geophysics, in China. Both have tried to solve a current enigma since, a few decades ago, it was confirmed that the Earth contains a planet inside another.
