On December 21, 2012, we entered the Age of Aquarius. Many unrelated ancient calendars have referred to this day as the beginning of a new era. There will be a density shift, where we are immediately propelled into a completely different reality. David Wilcock says that in the next few decades, we will see the return of Jesus Christ in the entire human race.
The shift to 4th density is very gradual and began in approximately 1936. 
Around 2001, Blue Avian spheres began to enter the solar system. By 2015, over 100 of them had entered, with some of them being as large as Jupiter. Their purpose is to diffuse the energy emanating from the center of the galaxy so that it does not adversely affect humans. It could potentially result in insanity. This ensures that the maximum amount of humans can ascend.
