Ancient, primordial helium that was forged in the wake of the Big Bang is leaking from Earth's core, scientists report in a new study.
There's no cause for alarm. Earth isn't deflating like a sad balloon. What it does mean is that Earth formed inside a solar nebula – the molecular cloud that gave birth to the Sun, a detail about our planet's birth that has long been unresolved.It also suggests that other primordial gases may be leaking from Earth's core into the mantle, which in turn could yield information about the composition of the solar nebula.
The other stable isotope, accounting for just about 0.000137 percent of Earth's helium, is helium-3, with two protons and one neutron. It's the Helium-3 isotope that has been detected leaking out of Earth's interior, mostly along the mid-ocean volcanic ridge system, giving us a pretty good indication of the rate at which it escapes the crust.from the University of New Mexico."It's a wonder of nature, and a clue for the history of the Earth, that there's still a significant amount of this isotope in the interior of the Earth.
This would tell us the source of the isotope. When Earth formed, it did so by accumulating material from the dust and gas floating around the newborn Sun.
