The Dark Star: The Planet X Evidence - Plot & Excerpts
The Great Water Conundrum My colleague, Lee Covino recently sent me an article from "Science News" (Vol. 161, no 12) about the source of Earth's oceanic water.1 Written by Ben Harder, the article outlined the latest scientific thinking about where all the water on Earth came from. This is a particular problem for planetary scientists, because the Earth simply should not have the amount of water that it does. The Earth is relatively close to the sun, and water, a volatile, should have been expelled from the early inner solar system before the Earth formed. As such, the Earth should really be a much drier planet. So where did all the water, that is so crucial to the biosphere of this planet, originate? Ben Harder describes various theories that are currently doing the rounds in scientific circles. Up until recently, the leading theory was the notion that the oceans were deposited by comets impacting the newly formed Earth (the 'late-veneer' hypothesis).2This bombardment occurred over a billion year period (and might also explain how life appeared on Earth so early in its geo-history).
