You[ll never see it coming until it is too late, from North America. However, it's obviously coming from a direction that is suitable for viewing
from Antartica. Why else would the Vatican build a telescope in Antartica?
Nobody is going to see it coming, because it isn't coming.
Now a spaceship of some sorts hiding behind the sun, that's a different story.
My suggestion is we either put a camera on another planet, one which will be opposite the Earth when the camera becomes functional, so we can see
behind the sun. This might take a long time to happen. But, then, we have all the time we need before Nibiru shows up. Like forever?
Better yet, lets ask Ed Dames to remote view from the other side of the sun. I hear he is really good at such things. He even remote viewed Satan!
He was quite surprised to find out that there actually is a guy named Satan and he's the Devil! Yikes!
And not to mention, found a really hot girl living in Ukraine to marry.
Imagine all the strange sorts of paths Nibiru must travel, just to remain hidden behind the sun from us Earthlings!
