Is Planet X / Niburu causing comets to fall into the solar system from the Oort Cloud?
Recently astronomers have seen evidence of disturbances in what is called the Oort Cloud. They theorize that these disturbances could be caused by a large object, possibly even an undiscovered planet, which they dubbed Planet X. Such a planet would stay outside our solar system in the Oort Cloud, but may be responsible for comets falling into the system in a somewhat regular pattern as it knocks them out of the cloud. This Planet X could never have been in, nor fall into, the inner solar system based on what we know of gravity and orbital mechanics.
