It's the biggest hoax of our century. We're talking about #chemtrails, always at the center of great conspiracy theories, often very imaginative.
The truth was established by first scientific study conducted by the University of California Irvine, the results of which were published in the journal Environmental Research Letters. According to the researchers, the trails are just simple, explainable chemical and physical phenomena. It seems instead that 17% of the world population believe that the trails are the sign of some strange government experiment.
They have been interviewed 77 experts in this regard, chemists and other scholars: "Of the 77 experts - states the author of the study -, 76 did not find proof of existence of a secret government program, they did not find the existence of such a program to be the simplest explanation for what we were subjected them and proposed explanations based on known physical or chemical theories.”
What then is the cause? Second some, the increase in attendance of aluminium, barium or strontium, due to industrial and agricultural changes or natural processes. “Focus on one secret spraying program and on a large scale it could distract attention from the real problems that need to be addressed,” reads the study's conclusions. But, we are sure, there will still be those who believe the conspiracy story.
