Flat-Earthers have found 'proof' - and an activity - that the sun is close to the earth.
This proof comes in the existence of parhelia, better known as sun dogs or mock suns.
YouTube user RebelWithoutaPause has posted a video online entitled 'Flat Earth, W.T.F is a sundog?' which purports to show evidence that the sun is much closer to the Earth than accepted wisdom would have us believed.
In the comments, the video's poster argues that various institutions have formulated an elaborate set of lies which would have us believe numerous untruths about the physical form of the universe.
"I don't believe ANYTHING from mainstream, from school teachers, university professors, the media, its a layer cake of lies, to keep us dumbed down," said the YouTuber.
"Don't be a fool all your life, take a day off, research Flat-Earth with an open mind, that is why I am looking for alternative answers because the ones, like the one you described, is straight out of their playbook.
"It's all smoke & mirrors , F. E. lifts the veil . the truth shall wake you up !"
Sun dogs are caused by refraction of sunlight by ice crystals in the atmosphere. They can be seen in any part of the world but are not always obvious, and are best seen when the sun is near the horizon.
Hexagonal ice crystals act as prisms, which bend light rays as they pass through them. This refracts light horizontally, so that sun dogs can be seen to the left and right of the sun.
To the naked eye, sun dogs can appear to be akin to two separate suns flanking the sun with a 22° halo.
Despite the fact the video's author has conflated every school teacher, university professor, journalist and whatever the mainstream is (I think it's The 1975) into one collusive entity, a quick through the video's comments provides all the info you need to know about the likelihood that the Earth is flat and the sun is our next door neighbour.
Those presenting scientific facts which have been tried, tested, questioned, re-questioned and tested again over hundreds (arguably thousands) provide links to websites with information by people who have devoted their lives to science.
They also provide explanations as to what sun dogs are in a relatively digestible way.
What they don't do is posit vague, often evasive counter arguments in BLOCK CAPITALS, which in no way adds weight to an argument (see above), make vague claims that Charles Darwin disputed the theory of evolution (he didn't, he promulgated it as a theory to be tested, hence the word theory), use the phrase 'wake up' or countless exclamation marks as some kind of definitive, debate-ending answer.
