Society of the world again dihebohkan with the emergence of a black ring that floats in the sky. Some people suspect the black ring is a portal that uses aliens to come to Earth. A week ago, the UFO-shaped black ring appeared on the M26 motorway, near Birkenshaw, Yorkshire, England. With a width of hundreds of meters in diameter, the strange object is nicknamed "whirlpool". One of the eyewitnesses was Kimberley Robinson who spotted the smoke whirl of glitter with his girlfriend, Danny Cooper. Carefully, Kimberley photographed the whirlpool with his smartphone camera. "Me and my boyfriend are driving today and seeing a black ring flying in the sky, looks like smoke but the shape is a sturdy ring," said Robinson, who thinks the Ring is a smoke of fire. However, West Yorkshire Fire Department said there were no fire reports on Sunday at 1330 local time. Not the first time, though it sounds weird, what happened to Kimberley was not the first time. On April 27, 2016, an amateur video showed the same thing: a strange cloud hovering over Disneyland Magic Castle in California. In the recording, eyewitnesses cheered hysterically. "Do not know if this can ... (I'm just) walking on the main street Disneyland following the parade.That's a windy night, (so) there can not be a smoke ring," said video recorder, Kyle Hawkin. He continued, everyone watched in bewilderment. I was half expecting an alien portal to open this ring as we stared in disbelief ... The strangest thing I've ever seen. In addition, by 2015 record a vortex of clouds emerging from Kazakhstan. With a diameter of 100 meters, dark circles float in the clear sky. Toughness is seen about 65 kilometers north of the capital Astana and after 15 minutes of flying, the vortex disappears without a trace. Simple explanations Various theories arise thanks to the various events above. Some people identify with foreign visions and portals between space and time. However, there is a simpler explanation. "The smoke ring in the sky like this looks very sinister and unusual," said Nigel Watson, author of 'UFOs from the First World War' to MailOnline. He explains, in this case (Birkenshaw), a black ring instead of a spacecraft from a Zog planet sent by an evil alien, but a by-product of cannon fire in the re-battle of Yorkshire Wartime events held nearby.Yorkshire Wartime, the festival Demo of World War I and II, involving more than 500 military vehicles And 50 war games. The festival takes place near the passing Robinson, on the M26 motorway. Fire flames also create smoke rings and disturbances in the surrounding air that produce vortices. The air around the maelstrom is slammed, while the air in it spins. (Source: kompas.com)
