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.
