Most of you who have heard of CERN will have heard of the LHC (Large Hadron Collider) the largest scientific instrument which exceeds 20 miles in diameter and travels under the sovereign territory of two countries (Switzerland, France). The public has been told that it was constructed at a cost of tens of billions of Euros for the purpose of studying the birth of the universe and the collisions that take place within the collider allow us a quick glimpse at certain phenomenon that can only be witnessed when particles hit one another at incredibly high rates.
This is NOT what the machine was designed for, nor is it what the machine has been used for since it's inception.
CERN's main purpose for building the Collider was too, well it was to open a door way.
Allow me to explain: the doorway idea came into fruition in the 1960s. After years and years of attempting to hide UFO phenomenon, including large scale and very public interactions such as the Roswell incident, and the Battle for Los Angeles incident well before that, the governments of the United States, Great Britain, and France decided to throw their weight behind the understanding of what precisely these objects were.
