Comets Bring Microbial Life edit

The Hoyle-Wickramasinghe panspermia theory proposes that life on earth was originated approximately 4 billion years ago by comets containing microbial life. Some of the microorganisms continue to be found. Nowadays Panspermia is considered as a serious alternative to life being originated solely on earth [1].

Methods edit

Research demonstrated that bacteria can survive the extreme conditions that it endures on space. It can withstand radiation as well as extremely low temperatures. During the 1970’s inorganic dust had properties identical to particles of bacterial composition. These bacteria were primarily found in interstellar dust and can trace the origin of some particles on earth. Replication of these particles is not possible in the interstellar environment; Therefore Hoyle-Wickramasinghe suggested then that microbial life follows the amplification process that stars, comets and planetary systems go through on the cosmic life cycle. Comets are then considered to amplify microbial life during this life cycle that can last a few billion years. [1].

Results edit

Microbial life on earth can be dated back to around 3.8 billion years (3.8 Gy) when comets and asteroid were bombarding the earth. This microbial life can be found or earth in new habitats such as geothermal vents, ocean floor, radioactive dumps and Antartic soil. The microorganisms recovered from the Earth’s crust prove that microbial life can survive the pressure of the ocean depths. Recent discoveries continue to support that microbial life was transferred in the cosmic life cycle and therefore transferred to earth. [1]
