Experiments and Evidence for the Detection of the Signs of Life in Meteorites and Comets, and in the Stratosphere►
About the Group
Welcome to my group. This is the place where we plan to maintain all the latest papers relevant to this subject, and the place where we can track the experiments and evidence around the general hypothesis that comets and meteorites can and do contain “life” in all its various forms and status.
For this group summary I include our current definition of the Hoyle-Wickramasinghe Model of the Panspermia Hypothesis defines the following propositions to guide the investigation: (Proc. of SPIE Vol. 8865 88650Q-5) 1. that dormant viruses and desiccated DNA/RNA can survive unprotected in interplanetary space (Radiopanspermia) 2. that the seeds of life can survive protected from cosmic rays in asteroids, comets and meteors (Lithopanspermia) 3. that the seeds of life are promulgated from solar system to solar system by a process of comet and asteroid collision with planets; matter ejection from planet to local planets and Moons; and then onwards and outwards from that solar system to an adjacent solar system
In the above propositions of the Hoyle-Wickramasinghe Model, the “seeds of life” include biological microparticles such as bacteria, viruses, spores and pollen. This specifically includes: 1. desiccated and/or partially inactivated DNA/RNA 2. live, dormant or fossilized non-cellular life (viruses) 3. live, dormant or fossilized cellular life (bacteria, archaea)
I recommend the first paper you read is “Life is a Cosmic Phenomenon” by my colleague William E. (Bill) Smith. This was presented at SPIE in 2013 and is a good summary of Panspermia and the “Difficult Challenge of the Search for the Signs of Life”.
