What are the changes that are coming with the entrance of the Earth into the Rings of Alcione? 

Answers from the books of Samael Aun Weor

“Alcion” has rings like the ones of Saturn but radioactive, not just chemical-physical as the rings of Saturn.It is a radioactive ring that brings many surprises to the men of Jinns Science.
Incredible things will be seen at the moment when Earth enters into the Rings of “Alcion”:

All the matter will become phosphorescent and the molecules will alter their movement, therefore, the mathematical formulas in the field of biology, chemistry, physics, will be altered; medicine will have to change its formulas because they will be useless; new species of animals will appear and this is something unavoidable... Matter will be strongly radioactive; many people will not resist the radiation of the “Alcion's” Rings and will die.

I repeat, we are about to enter in that ring. As a matter of fact, if the Sun enters first, there will be darkness that will last 110 hours. If Earth enters first into the ring of “Alcion”, it will happen that Earth will seem to be burning, but it only be fires of colors. Earth can enter anytime into the ring of “Alcion”…

…As a matter of fact, a very long day which will last 2.000 years is coming, this means that night will disappear and the luminous radiation of “Alcion” will penetrate all the tenebrous caverns of Earth and cover the planet everywhere, shining miraculously; its emanations will amaze the people of other inhabited worlds of the unalterable infinite. In this manner will come the marvelous resplendence of the stars which will come accompanied by the melodies of the Macrocosm... Very soon, an estrange world will appear: that world is called Earth!
