Quote:This is why provenance is so important with meteorites. Buy from a trusted dealer and you will get genuine meteorites. Buy from an unknown or some random seller on eBay, and you have no idea what you are actually getting.

Quote:I'm very concerned about how fake meteorites made with 3D printers could dramatically alter meteorite values. Is this something that is already starting to happen? I don't know if 3D printers can make fakes YET. I do know that something shook me up that is in the current Astronomy magazine on page 13 (April 2013) It stated that 3D printers can create small objects out of synthetic Moon rock material.
Several weeks ago I posted my concern about 3D printers on the Off Topic Observatory but the vast mojority of responders only had high praise for these gizmos. Is there any concern at all from meteorite collectors?

Quote:Carey is right, there are properties inherent to meteorites that cannot be replicated on Earth - such as the formation of chondrules.

Quote:Quote:I would gladly get rid of all the nuclear weapons in the world if the cost was losing all the nuclear power plants.Why are people always so willing to get rid of all the good to reduce the small possibility of bad? The bad that comes with something will always be managed well if the good it brings is worth it.
