Our planet contains mysteries that are yet to be unravelled. Many them focus how the Earth formed, and what is the centre our planet. A recent study provides clues as to what shaped Earth the beginnings of our solar system. Scientists say they have discovered evidence that vast amounts a rare, primordial form of the gas helium may be trapped Earth's core. It is called helium-3. Scientists universities in Japan and Taiwan believe the helium-3 is from a giant cloud gas and dust that amalgamated to create different planets. The gas has remained locked Earth's mantle billions of years, but is occasionally released in volcanic eruptions.
The research paper has created considerable excitement planetary geologists. They believe the presence large amounts helium-3 could unlock more secrets of the Big Bang. In particular, the scientists are speculating that there being so much helium-3 under the Earth's mantle could mean that Earth was created much more quickly than previously thought. Dr Peter Olson, a geophysicist the University of New Mexico, shed light on the possible speed Earth's creation. He said: "There is evidence that has been interpreted to say the Earth formed very slowly, requiring 100 million years. [However], you wouldn't get much helium deep the Earth if the Earth formed that slowly."
