Regarding the "dust'' supposedly brought from the moon, that dust can be gotten anywhere. It has already been openly admitted that the same dust is available on this earth planet. These astronauts and scientists are all bluffing. But Srila Vyasadeva is the correct authority. Just study Srimad-Bhagavatam carefully with full faith in Krishna and Guru and all knowledge will be revealed.
