10 Bizarre Theories About The Earth That People Believe

2013/5/29Contracting Earth Theory, or geophysical global cooling if you want to get all science-y about it, was a theory before the idea of plate tectonics ever came about that said the Earth is actually getting smaller over time, and the shrinking Earth is what causes natural disasters as well as the natural wonders of nature, such as mountain ranges.

The Rare Earth Hypothesis

The Rare Earth hypothesis suggests that Earth-like planets containing complex (animal) life as we know it are likely quite rare in the Universe. This lesson will explore several parameters that have led the scientists Peter Ward and Donald Brownlee to put forth this hypothesis in their book, Rare Earth: Why Complex Life is Uncommon in the Universe .

Sentient Developments: The 'Rare Earth' delusion

The rare Earth hypothesis is about rare intelligent life, not about rare life. It is quite possible that 99.999% of all worlds which evolve life never evolve intelligent life. The evidence used in the discussion of the Fermi Paradox is clear: there is no intelligent alien life in the Milky Way. Get price

[1304.3381] Life Before Earth

2013/3/28An extrapolation of the genetic complexity of organisms to earlier times suggests that life began before the Earth was formed. Life may have started from systems with single heritable elements that are functionally equivalent to a nucleotide. The genetic complexity, roughly measured by the number of non-redundant functional nucleotides, is expected to have grown exponentially due to several Get price

China 'huffs and puffs' on rare earths, but history suggests

One rare earth trader warned Fastmarkets that history has shown us that China can use rare earths supply as a weapon if it feels threatened. The threat of a rare earth export embargo is not new. In 2010, China attempted to cut off rare earth exports to Japan after a dispute over the ownership of a group of islands in the East China Sea, which sent prices briefly surging upward. Get price

2002/11/9The rare-earth element concentrations are not typically affected by sea and river waters, as rare-earth elements are insoluble and thus have very low concentrations in these fluids. As a result, when a sediment is transported, rare-earth element concentrations are unaffected by the fluid and instead the rock retains the rare-earth element concentration from its source.
