You are not paying attention. 3i should have changed course slightly for 2 reasons. One, it is on the same plane by 5 degrees as our planets in the solar system but their forces have not altered it's course. Secondly, with the enormous amount of particles it is emitting, that hasn't affected it's course either. The cloud of particles going before it defy any other known objects. It is also displaying lightning now. It has also changed colors at points that make no sense. Try to keep up. These things are happening for a directed reason.
