"The near-Earth plasma sheet is thought to thin during the growth phase and then rapidly expand after the onset of the substorm." -- J.P. Dewhurst, astrophysicst, et al., 2004
Science Daily: Earth's Atmosphere Came from Outer Space, Scientists Find.
ScienceDaily (Dec. 11, 2009) — The gases which formed the Earth's atmosphere -- and probably its oceans -- did not come from inside the Earth but from outer space, according to a study by University of Manchester and University of Houston scientists.How can the Earth gain matter from outerspace without growing? I guess the particles have negative mass.
The report published in the journal Science means that textbook images of ancient Earth with huge volcanoes spewing gas into the atmosphere will have to be rethought.
According to the team, the age-old view that volcanoes were the source of the Earth's earliest atmosphere must be put to rest.
