Since most of the top secret projects are hidden, we do not know if Nibiru is indeed on an orbit that would get considerably close to planet Earth.
We cannot refute the idea that Nibiru exist because we know so little about what the Government has up its sleeves up to now.

Anyhow, even if Nibiru would be coming, they would never admit that a planet that big will eventually cause big catastrophes on planet Earth in a future to come.
