Scientists discovered a leak in the earth’s core that could indicate the formation of our planet. Earth has evolved for over a billion years, and the cause of its formation is still shrouded in mystery.
Scientists have discovered helium-3 which is a rare isotope of helium gas, leaking from the earth’s core. This detection of helium-3 indicates the deep puddles of this element. This antediluvian gas formed in the meantime after the big bang. however, it is possible that the formation of this antediluvian gas can be because of natural phenomena, such as radioactive decay of tritium, either way, it is was acquired in the nebula.
"Mainly produced by the decay of uranium and thorium, terrestrial Helium-3 is large of primordial origin, synthesized in the aftermath of the Big Bang (Bania et al., 2002) and incorporated into the Earth primarily during its formation,"- The study published in the Journal AGU Geochemistry, Geophysics, Geosystems stated.
According to NASA, Nebula is made of dust and gases which is mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. The clumps and dust consequently become bigger and the gravity also gets stronger resulting in the collapse of the particles.
Evidence suggests an object one-third the size of the Earth hit the earth at its early stages after formation, and due to that, it would have resulted in the re-melting of the Earth's crust, allowing much of the helium to escape. The gas continues escaping to this day.
With the help of the modern helium-3 leak rate and its isotopes behaviour, it was possible to estimate the amount of helium-3 in the earth’s core. According to researchers' estimation, there are ten teragrams to petagrams of helium-3 in the core, which is a very vast quantity.
