Observable Facts Related to Creation and Evolution of the Earth
During the second half of the twentieth century, many advances have been made in the field of cosmogenics. New facts and rich general information in physics of space near the Earth, the Moon, and nearby planets Mars, Venus, Mercury, and Jupiter were obtained by means of cosmic apparatus and techniques. Lunar rock samples brought back to the Earth by astronauts and automatic space devices have provided much data on the physical-mechanical properties of those rocks and on that basis a number of new cosmophysical and cosmochemical conclusions have been drawn. Due to new techniques available for studying natural substances, much knowledge was gained on the chemical and isotopic composition and the absolute ages of meteorites, lunar and terrestrial rocks, water, and gases.
