And for many viewers outside of the US it is understood that the dimension is 1cmX1cmX1cm; but for the common "uneducated" ebay buyer the cube has no meaning. Therefore by stating the dimensions in the text would provide more clear information for most viewers. As for field geology, the cubes would be useful; but commonly the field geologist is left with using a coin, lens cap, pen, pocket knife, rock hammer, or something else that he/she happens to have available. Now about Planetary material. Science is a dynamic and hopefully progressive method to explain what is being studied. Science cannot say with 100% certainty that this or that meteorite came from this or that planetary body. We can state the evidence we have that indicates, with some degree of certainty, that this or that rock came from where....sometimes. The types of rocks and environments on most planetary bodies should be highly variable....look at the variety of rocks and minerals on the Earth for example. Planetary bodies are dynamic, and atmospheric gas and rock formation processes are variable throughout the formation and life of the planetary bodies. Impacting meteorites from another source can "contaminate" the surface samples that are/have been collected. Thank you both and list members for this debate. Sincerely, Dirk Ross...Tokyo __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
