Encyclopedia of Pestilence, Pandemics, and Plagues entry. The continued arrival of comet debris to Earth at the rate of some tons per day must surely bring in new bugs. First Phase of Lithopanspermia Experimentally Tested”. In an Origins Symposium presentation on April 7,physicist Stephen Hawking stated his opinion about what humans may find when venturing into space, such as the possibility of alien life through the theory of panspermia: Comets — A vehicle for panspermia.

The aim is to collect large quantities of stratospheric air using sterile equipment cryopumps carried aboard balloons, and to search these samples for hints of alien microbial life.

The analysis of carbon bubbles found in a meteorite shows they are not Earth contaminants and must have formed in temperatures near absolute zero. Alternatively, the wild land and marine bacteria as well as the ISS bacteria may all have an ultimate space origin.

The Nobel prize winner Francis Crickalong with Leslie Orgel proposed that life may have been purposely spread by an advanced extraterrestrial civilization, [48] but considering an early ” RNA world ” Crick noted later that life may have originated on Earth. Retrieved 3 December This single location in All: Fred Hoyle — and Chandra Wickramasinghe born were influential proponents of panspermia.

Some think that the hugely improbable transition from non-living to living mat ter can be achieved by dividing the transition into many small steps, calling on a so-called ‘evolutionary’ process to bridge the small steps one by one. From Fossils to Astrobiology: Wallis and Wickramasinghe argued in that the transport of individual bacteria or clumps of bacteria, is overwhelmingly more important than lithopanspermia in terms of numbers of microbes transferred, even accounting for the death rate of unprotected bacteria in transit.
