Searching deeper through laboratory experiments and computer simulations, researchers working at the Eidgenossische Technische Hochschule (ETH) Zurich have formulated a new theory regarding the formation of the Earth. Through their study, researchers created models to illustrate how planets formed in our solar system and threw light on their composition.

“The prevailing theory in astrophysics and cosmochemistry is that the Earth formed from chondritic asteroids. These are relatively small, simple blocks of rock and metal that formed early on in the solar system,” announced Paolo Sossi, Professor of Experimental Planetology at ETH Zurich and lead author of the study published in Nature Astronomy.

Some have recommended earlier that clashes of objects that resulted in the creation of the Earth produced extreme heat because of which lighter elements vapourised and left the planet in its present composition.

However, according to Sossi, these theories don’t appear to be reasonable when someone analyses the isotopic composition of our planet. The lead author emphasized that isotopes of an element contain the same number of protons but a different number of neutrons. Technically, isotopes with fewer neutrons are lighter and, therefore, should exit first. But, according to the heat vaporization theory, there should be fewer light isotopes on Earth right now. However, this isn’t true.

Presently, researchers think that they have a better prototype to explain the creation of the Earth and a reference to observe the formation of other rocky planets.
