If you've opened up social media in the past few days, you must have come across a lot of people talking about such a "noise from the sky". On Twitter, the term reached the top spot in trending topics and became the most talked about subject on networks among Brazilians. But what the hell was that?
The subject mentions some alleged videos of people saying they heard strange noises in the sky. The sound, in this case, would look like airplanes or construction noise without, however, having any indication of both.
First of all, it's good to note: you can't guarantee any authenticity of any of the videos cited by Internet users. Likewise, it is almost impossible to find the primary sources of the alleged videos to understand where this started. For this reason, you can already begin to see this whole story with a backward footing.
Listened to by Tilt, the physicist at USP (University of São Paulo) Paulo Artaxo soon stated that these noises are meaningless and would be "fake news of those who are stuck at home and want to do something".
Supposed explanations for the noise circulating online would involve natural noises from the Earth, such as gas movements. Even quarantine, with less pollutants in the air, would have helped those noises. None of this convinces Artaxo, however.
"It makes absolutely no sense, there are no natural noises from the Earth. Less pollutants due to quarantine have nothing to do with it because the reduction in air pollution levels changes a lot, but very slightly the composition of the air and only in urban areas. This is the invention of those who have nothing to do ", he points out.
In fact, this would not be an original fake news. In 2012, several videos of alleged noises from the sky were posted on YouTube and even gained relevance. All, however, had been posted on at least the channel, which edited images with a trumpet sound taken from a film. It is most likely in the Brazilian case, too, for Artaxo.
Other theories suggest another collective delusion, which may work well in the Brazilian case. It works like this: a person says that he heard a noise and then several people come to believe that he heard that noise. The more people claim to have heard, the more people will start to replicate the information.
Then even everyday noises would enter popular paranoia – it makes even more sense because many are saying "now I heard it, it looks like a truck or plane". Well, it could be a truck or plane.
Anyway, this noise, at first, seems to be more exacerbated boredom of Brazilians with confinement.
However, there are those who defend the possibility that "noises from the sky" are something real. In a quick online search, you can see supposed reports of the type that have been occurring for decades in various locations around the world.
And then there comes an expression called "skyquake", even though it is not something scientifically spiked – as theory as "UFOs", ok? It is complicated, however, to distinguish the real phenomenon from the numerous false news on the subject.
Skyquakes would be more common in coastal areas and would have origins either human (like supersonic airplanes) or scientific (meteorites exploding in the atmosphere or gases moving under the Earth through small air passages).
There are even studies about a noise called "Hmm"that people in various parts of the world say they hear. Among the possibilities of what this could be are collective delirium (even mass, which is not uncommon in humanity) or low frequency sounds produced in large cities – and that may have exacerbated now that humanity is more "quiet".
Ah, the internet
Of course, the whole story became much more of a joke than reality on the internet – and that's why it came to the most talked about subjects. Below, you can check some of the tweets from internet users about what this supposed noise would be:
