Earth layers 'OUR' surface part is very thin and DELICATE,we affect weather etc by our pollution of the environment, the upper air protective lays such as ozone are being destroyed by our commercial air journeys and industry etc ,once this fragile layer is unrepairable as too badly damaged = WE HAVE NOWHERE ELSE TO GO !! Don't make jokes in the only lifeboat our species has ‼️
Chemistry says Moon is proto-Earth's mantle, relocated. Measurements of an element in Earth and Moon rocks have just disproved the leading hypotheses for the origin of the Moon. Read more at: http://phys.org/news/2016-09-chemistry-moon-proto-earth-mantle-relocated.html#jCp
Researchers used an experiment that relied on the electrons (red dots) in Earth's mantle to look for new particles, possibly the unparticle, that are tied to a new fundamental force of nature called the long-range spin-spin interaction (blue wavy lines). The white arcs represent Earth's magnetic field lines.
