Certains endroits sur Terre semblent défier complètement les lois de la physique ! Prenez la cascade du Chaudron du Diable dans le Minnesota, où la moitié de la rivière disparaît mystérieusement dans un trou, et personne ne sait où elle va ! En Bolivie, le Salar d'Uyuni se transforme en un immense miroir après la pluie, ce qui donne l'impression que vous marchez sur le ciel. Ensuite, il y a la Colline Magnétique au Canada, où les voitures semblent monter une pente, bien qu'il s'agisse techniquement d'une illusion d'optique. Au Turkménistan, les Portes de l'Enfer sont un immense cratère enflammé qui brûle depuis des décennies après un accident de forage — c'est d'un autre monde ! Et en Australie, le Rocher de la Vague ressemble à une énorme vague figée, même si c'est simplement une formation rocheuse solide formée sur des millions d'années. Ces endroits font de la Terre quelque chose qui semble tout droit sorti d'un film de science-fiction !

FunTranscript
00:00Thousands of years ago, a huge meteor of 2 million tons hit the Earth at a speed of about 90,000 km per hour.
00:08This colossal impact actually gave birth to the Lake of Lonar in Maharashtra.
00:13Seen from the sky, this lake may seem ordinary.
00:16But the sand that surrounds it is magnetic, which disturbs the navigation instruments.
00:21First of all, it is a sodic lake.
00:23And no, it is not filled with soda, but this term simply means an alkaline lake.
00:28Its pH level varies between 9 and 12, while the comfortable pH range for humans is between 6.5 and 8.5.
00:36As a result, it is highly advisable to bathe here, and even less to drink water.
00:42A small circular depression, located about 700 meters from the main lake,
00:46would have been, according to some, caused by a fragment of the original meteor.
00:51Nearby, a temple dedicated to Hanuman houses a statue carved in the rock,
00:56famous for emitting powerful magnetic vibrations.
01:00In addition, local farmers draw water from the lake below.
01:04This lake is sometimes designated under the name of Chota Lonar, which means Little Lonar.
01:10This almost oval crater is one of the rare natural craters in the world,
01:14made entirely of basalt, a dark and finely granulated volcanic rock.
01:20The water there is seven times saltier than that of the oceans.
01:23And the lake can occasionally turn pink due to certain bacteria.
01:28Every time you open a tap to fill a glass, water flows from top to bottom under the effect of gravity.
01:34Of course, it is difficult to imagine the opposite phenomenon.
01:39However, some waterfalls seem to challenge gravity by going up.
01:43These inverted waterfalls occur when strong winds of more than 70 km per hour
01:49blow in the opposite direction of the waterfall, propelling it upwards.
01:54This spectacular phenomenon mainly occurs during the months of autumn and winter,
01:58when the winds are often more violent.
02:01Contrary to what one might imagine, inverted waterfalls are not so rare,
02:05and can be observed on all continents, from Australia to India,
02:09through Japan, the United Kingdom and the United States.
02:13In Australia, in regions such as Sydney, the Central Coast and the Royal National Park,
02:18winds of more than 70 km per hour can make the water rise and fall.
02:23This phenomenon is explained only by the force of the wind at this speed.
02:26Forget all the crazy myths linking this phenomenon to the Southern Hemisphere.
02:30The idea, for example, that the water of the toilets flows in the opposite direction,
02:34is only an urban legend.
02:36In India, near Bombay, and in places such as the Sandan Valley or the Amboli Hills,
02:41waterfalls are pushed back to the sky during the monsoon.
02:44And in the Iron Islands, this spectacular phenomenon occurs regularly,
02:49thanks to the unique geography of the region and the powerful winds of the North Atlantic.
02:54The Ladakh Magnetic Hill, in India, is an intriguing sight,
02:58nestled at an altitude of about 4,300 meters along the Srinagar-Leh highway,
03:03only 26 km from the city of Leh.
03:06This hill mysteriously defies gravity.
03:09The vehicles, left to the death, seem to go up by themselves.
03:14This anomaly attracts visitors from all over the world and feeds local legends,
03:18which see a bridge between the earth and the sky.
03:21The ideal period to visit is from June to September,
03:25when the conditions are perfect and the illusion of optics is at its peak,
03:29usually between 8 and 17 hours.
03:32In Brazil, there is a street called Rua do Amendoim,
03:36which intrigues everyone who steps on it,
03:38on foot or by car, due to its unusual effect.
03:41Affectionately nicknamed the street of Arachide, by the locals,
03:45it never lacks a parking space.
03:47The cars parked without starting the handbrake
03:50spontaneously begin to ride uphill, gaining speed little by little.
03:55Many theories circulate to explain this unusual phenomenon.
03:59Some claim that the hill would be haunted,
04:02while others believe that an iron deposit would attract cars to the top like a magnet.
04:08In reality, this phenomenon is only an illusion of optics.
04:12The street seems to be ascending,
04:14but actually has a slight slope down.
04:17The cars that seem to be going up and down, in fact.
04:20However, this did not discourage visitors,
04:23who continue to film this curiosity with enthusiasm.
04:26Located on the superb coast of the Black Sea,
04:29Urequi is a peaceful seaside resort,
04:32famous for its unique magnetic sands,
04:34oriented towards well-being and health.
04:37These sands, recognized for their healing virtues since the 19th century,
04:41are used to relieve various health problems.
04:45The particularity of Urequi sands lies in their mineral richness,
04:49such as magnetite and quartz.
04:51With a magnetic content of about 23%,
04:54their magnetic field is much more intense than that of ordinary sand.
04:58The lights of Esdalen are mysterious orbs visible on a 11-kilometer-long trench
05:04in the valley of the same name, in the heart of Norway.
05:08These luminous phenomena, observed since the 1930s,
05:11can appear both during the day and at night,
05:14generally shining in white, yellow or red.
05:18These lights can glide, move quickly,
05:21or sway gently in the air.
05:23Their manifestation lasts a few seconds to more than an hour.
05:27Although there was a peak of observation between 1981 and 1984,
05:33the frequency has fallen to reach about 10 to 20 annual appearances since 2010.
05:39Research groups, such as the Esdalen Project,
05:42have been carrying out various investigations since 1983,
05:46combining field studies and scientific research
05:49to unravel the mystery of these lights.
05:52As for their origin, the mystery remains.
05:55Some appearances have been attributed to the reflection of car headlights
05:59or astronomical objects.
06:01A theory suggests that they would come from a chemical reaction
06:04involving dust in suspension from local mines.
06:08Others hypothesize that they would be a cluster of particles
06:11interacting specifically due to the geological peculiarities of the region.
06:15Some scientists hypothesize that these lights
06:18could be generated by a piezoelectric effect due to the rocky composition of the valley.
06:23Others advance the idea of complex interactions
06:26between electromagnetic waves and dust particles,
06:29which would explain the singular shapes and colors of these luminous apparitions.
06:34The dust of the Sahara, which has even reached certain regions of the United Kingdom,
06:37and covers the cars with a reddish layer,
06:39is composed of naturally magnetic minerals.
06:42On September 7, 2023,
06:45several people noticed that their vehicles were covered with reddish spots
06:49due to the dust blown from the Sahara.
06:52A video shared on Facebook showed a person using a magnet
06:56to remove the dust from his car.
06:58A commentator also took note, saying,
07:01If you want to know what fell last night,
07:04just take a magnet and look at that,
07:06insisting that it was metal and not sand.
07:10Naturally, this discovery sparked discussions
07:13about the possible link between the magnetic properties of this dust
07:17and the famous chemtrails.
07:19But guess what?
07:20Experts are clear,
07:22this magnetism is quite normal for Saharan dust.
07:26According to Professor Barbara Maher,
07:28from the Environmental Magnetism and Paleomagnetism Center
07:31at the University of Lancaster,
07:33dust carries a mixture of particles from African soil
07:37and atmospheric pollutants on its way to Europe and the United Kingdom.
07:41The red color comes from hematite,
07:43a weakly magnetic mineral.
07:45Of course, dust can carry magnetic particles of human origin along the way,
07:50but scientists say that they are generally much less abundant
07:54than those of natural origin.
07:56The idea of chemtrails,
07:58according to which planes would deliberately spray harmful substances,
08:02is based on conspiracy theories,
08:04which are most often refuted.
08:06In short,
08:07the presence of magnetic particles in Saharan dust,
08:10like the hematite that gives it its reddish hue,
08:13does not support such a theory in any case.
08:16Not having access to the Internet in 2024 seems quite unusual, doesn't it?
08:21When we talk about access to the Internet,
08:23it mainly refers to wired connections,
08:26mobile networks,
08:27as well as satellites.
08:29Fiber optic cables connect most of the world,
08:32with the exception of Antarctica,
08:34as well as many small islands.
08:36Mobile networks are also very widespread,
08:39and even in remote regions like the Sahara,
08:42you can sometimes find limited access.
08:44For those who live in rural areas,
08:46satellite Internet is often the best option,
08:49although slower.
08:50However,
08:51there are still some truly isolated places.
08:54Deep caves,
08:56like the Croubera-Voronja Gorge in Georgia,
08:58do not benefit from connections because of their depth.
09:01And under the ocean,
09:03signals have a hard time finding their way,
09:05making Internet access either weak or non-existent.
