Nibiru doesn't exists. This is a fact. But i was thinking that IF Nibiru existed and were on a collision course for Earth, NASA's David Morrison would say: "Nibiru doesn't exists". Why? NASA is a government agency, and general hysteria could be bad for the country (USA in this case) and his economy, like assaults, riots, crisis and panic. So, there will be ever a conspiracy. Not in this case, because even amateur and professional astronomers (Ph.Ds: my preferred).
But NASA has experience that normal astronomers does not have.
So, what is your opinion?
