Talk:Panspermia/A Critique of Protection of bacterial spores in space, a contribution to the discussion on panspermia


 * Adding to the above comment. No life on earth could not have been started by the idea of panspermia, you are correct. This maybe also why we can not find other living life forms on other planets surrounding our planet or any other habitable planets for humans to live on anywhere close to Earth. Mainly due to the fact we and the bacteria both need the right environment to live.

Also adding to the above comment. Richard B. Hoover's experiments determined that life on comets is possible. His findings suggest that planets such as Mars and their moons can sustain life since liquid water can be found on them. His evidence proves that life forms existed on the meteors prior to entrance into Earth and that some bacteria can flourish in high temperatures


 * Also adding to the above comment, Richard B. Hoover also found that the bacteria evidence that he had found showed that the bacteria can grow and withstand harsh conditions thanks to their protective shields that they had. With this, it enables bacteria to be able to withstand harsh environmental conditions that they may cause potential damage to this. It is important to keep in mind that not all bacteria may overcome these harsh conditions but enough did survive to help the promote the emergence of life.

 * A critique of the point.
 * It does not seem appropriate to say with certainty that Panspermia cannot have happened, science offers few absolutes, and very few to this question. Your assertion therefore is flat out incorrect. More to the point however, we cannot reproduce the conditions at which Panspermia occurred, if it did, to say for sure one way or the other. Therefore, it is possible that spores did arrive on earth to populate via Panspermia because there may have been an object that had just the right conditions to act as an incubator and transport vessel. You cannot say that no life can survive being transported through the harshness of space, as the very fact your alive is evidence to the contrary. It all depends on the fitness of the transport vessel in facilitating the task of surviving the environment, not the environment itself, that would allow one to make such a determination.

What I took from this article is that there is a possibility that bacteria could survive given the correct condition. The problem is that the correct conditions are difficult to maintain so panspermia is not very likely. Jhill171 02:16, 1 February 2012 (UTC)

The second last comment, you are correct in the fact they have found water on other planets but the ecosystems are still inhabitable for majority of living creatures including bacteria. The are various of different aspects living things need such as proper temperature, light and food( and their food need the right conditions as well.
