00:04Underneath our planet's crust lies the mantle and the Earth's outer and inner core all composed of molten rock and
00:10other elements.
00:11But now experts say despite what we've believed for hundreds of years, there might be yet another layer deep under
00:16our feet.
00:16Joanne Stevenson, a geophysicist with the Australian National University, and her team made the discovery,
00:21using computer algorithms that are able to sift through literally thousands of inner core possibilities using years of seismic data.
00:28And they found that there may have been two distinct cooling events in our planet's history,
00:32meaning that beneath the inner core lies yet another core, possibly comprised of different materials and having a different temperature.
00:38With Stevenson saying about the find, quote,
00:41The details of this big event are still a bit of a mystery,
00:43but we've added another piece of the puzzle when it comes to our knowledge of the Earth's inner core.
00:47Experts say this new theory could explain why researchers continue to find inconsistencies with regards to our current inner Earth
00:54models.
00:54With Stevenson adding that we might have to start rewriting our geology textbooks.
00:58боx.

01:02Whoever works on the other.
