It is the biggest hoax of our century. We are talking about the #chemtrails, always at the center of great conspiracy theories, often very imaginative.
To establish the truth was the first scientific study conducted by University of California Irvine, the results of which were published in the journal Environmental Research Letters. According to the researchers, the contrails are just simple chemical and physical phenomena that can be explained. Instead, it seems that 17% of the world population believes 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 - says the author of the study -, 76 found no evidence of the existence of a secret government program, they did not believe that the existence of such a program was the simpler explanation for what we were putting to them and they proposed explanations based on known physical or chemical theories. "
What then is the cause? According to some, the increase in the presence of aluminum, barium or strontium, due to industrial and agricultural changes or natural processes. "Focusing on a covert, large-scale spraying program could distract attention from the real problems that need to be addressed," read the study's conclusions. But, we are sure, there will still be those who believe in the story of the conspiracy.
