My understanding is that one of their applications is to reflect back sunlight in an attempt to stop cosmic rays from getting to the people. The whole galaxy is ascending to a higher reality, the game is moving higher. The sun and the galaxy are sending out rays to make this happen, signals that activate within us our own higher reality / vibrations etc. They are trying to block these nutrients which are beneficial to us moving higher from getting to us. They want to keep us locked in 3d so they can keep us as their food source and keep us enslaved. We are not slaves. Their attempts are quite frankly a little pathetic to keep us enslaved.
The Light of God never fails. There is victory and only victory for those who choose the Light.
