At the center of our satellite , warmth and pressure are so tremendous that even the anatomical structure of iron is transformed . Now , using optical maser and diamonds , researcher have reproduce those conditions in the lab . And find something they ’d always suspected .
The researchers conducted a series of “ compression experiment , ” and found that atomic number 26 crystals change their structure under tremendous estrus and pressure . But how did they do it ?
A squad of scientist took two diamonds , which you see above , and crusade their prostrate tips together . Then they compressed them to “ ultrahigh pressure , ” and heated them with lasers . Basically , that small spot between the two diamond became so spicy , and so compressed , that it was just like the Earth ’s nitty-gritty . Using x - beam diffraction measurements , the scientists were able to valuate what that flyspeck spot was going through , and extrapolate how those conditions would affect iron crystals .
accord to a release from skill :
Shigehiko Tateno and workfellow suggest that Fe crystals at the marrow of the Earth prefer a hexagonal close - packed anatomical structure rather than one of its other cubic structures , which are have it away to occur at ambient weather condition . . . The find also assist to explain some previous observance of seismic activity in the core , and it suggests that single iron quartz in the effect might point themselves with their farsighted , crystallographic axes parallel to Earth ’s rotation axis .
That ’s right – there are huge iron crystals aligned with the Earth ’s axis late in the satellite ’s inner gist . I have to take it sounds completely awesome , in a Balrog - is - about - to - emerge sort of mode .
