Conspiracy theorists latest claim is that world leaders are spraying chemicals into the skies to hide planet Nibiru, a mythical world that could potentially trigger an apocalypse.
They say the leaders are also using the moon and sun to hide it in this grand scheme, the Daily Mail reported.
Matt Rogers regularly posts conspiracy videos on Youtube to explain his theory. "Our skies are being sprayed to cover up the truth," Mr Rogers said in one video. He also shows a range of photos of the moon and sun spotted from around the world.
"Looking up we should see the moon, not that beam of light," he said in the video of an image of the moon over Austria. Adding," I do believe they are using another reflector up there - it does look very strange. That is not the moon."
He believes all this comes down to Nibiru also referred to as Planet X. "They spray the skies at specific times of the day and times of the month, and the pattern of spraying is so blatantly obvious that they're hiding something," he said in the video.
As bizarre it all sounds, many people agree with him.
"They have been spraying in CA heavy for a long time. I feel ill almost every day. It's hard to understand how our military would do something like this, but they are," Julie Dotseth is quoted as saying by the Daily Mail. While Nancy Simmons said: "The public is aware of the cover up by the government, Nasa. I have emailed our president asking him to tell us the truth, we the voters who put you in office, but hope the rest of you will do the same. Be safe all."
However, author of the UFO Investigations Manual Nigel Watson, is not convinces about these theories about the moon. "Seems like such theorists just don't want to accept a scientific viewpoint of the world, and believe any thing the "authorities" say or do is part of a plan to hide the "truth" about our "real" existence," he is quoted as saying in the report.
