Document Summary

After the big bang some cosmology and a little astrobiology. The following topics are available for the hadean eon: introduction, geological time scale, hadean chemistry, prebiotic biochemistry, compartments, panspermia (show me all this on one page). The earth is approximately 4,500 million years old but multicellular life only rose 500 million years ago. The first eon in earth"s history is the hadean and this was a very violent time in its history. Continuous bombardment and a molten planet gave way to the oceans as the earth cooled and the crust solidified. The atmosphere was unlike that of today"s with the most notable exception being the absence of oxygen. Laboratory experiments have demonstrated that lightening and volcanic gases reacted and created a prebiotic soup of simple organic compounds that was supplemented by the same compounds from deep sea hydrothermal vents and even from meteorite materials.
