FunTranscript
00:00In the North-East of Thailand, a family of huge stone whales swim in the forest.
00:06They are part of a rock formation that is 75 million years old.
00:10A long time ago, this part of Thailand was nothing more than a desert.
00:14The movements of the earth's crust have pushed the gravel upwards to create these fascinating mountains.
00:19Accessible to anyone who wants to spend the day exploring the network of trails,
00:23this site is more and more popular with tourists.
00:27Once you have reached the back of one of the whales,
00:30and that you will look at the infinite sea of green stretching down, you will understand why.
00:35On the detour of these paths, you will find waterfalls, a wide variety of plants and exotic animals,
00:40and from the top of the hill, you can even see the neighboring country, Laos.
00:46The shapes look like those of the whales swimming together.
00:49No wonder this place is called the Three Whale Rock.
00:53What a wonderful way to see Thailand on the back of a giant stone whale.
00:57By digging in a Canadian mine in March 2011, a worker made an incredible discovery.
01:03He found a specimen of Nodosaur, almost perfectly preserved.
01:08This extinct dinosaur weighed about 1,360 kilograms and was 5.5 meters long.
01:14Although it is more than 110 million years old, the Nodosaur was so well preserved
01:19that you can clearly see the heavy shell and the scaly skin it covered.
01:24It took almost a year of meticulous work to clear the incredible find.
01:29The fossil was finally unveiled in a Canadian museum in 2017.
01:34Unexpectedly, the analysis of the skin revealed nuances that indicate that the Nodosaur
01:39was perhaps capable of camouflaging itself, like geckos and night butterflies of modern times.
01:44This is added to the spines and scales that already make it an assault tank.
01:48Still studied today, this Nodosaur could be one of the most important fossils
01:53that has been discovered for a long time.
01:55Its secrets could help us elucidate many other mysteries of the past.
02:00Voynich's manuscript is the most mysterious document in the world.
02:04Since its discovery in 1912, it remains a complete mystery to all those who study it.
02:10It is abundantly illustrated with strange images of extraterrestrial plants,
02:14unknown objects and zodiac symbols.
02:17But its most interesting aspect is its writing.
02:20The language used in the text is completely indecipherable.
02:24No one knows what it means, who wrote it, or where it was written.
02:29We don't even know if it was a real functional language or if it was created for this one text.
02:35The drawings of the different plants are just as fascinating.
02:38Most of the plants in the manuscript are identifiable as plants,
02:41but they do not correspond to any known species.
02:45In England, a linguistics professor claimed to have deciphered some of the symbols in the manuscript,
02:51but to this day we have not been able to find more information on this mysterious text.
02:56If you ever get the chance to go to Australia,
02:59don't forget to visit the mysterious craters of Queensland.
03:02Halfway between Bundaberg and Djin Djin is one of the most disturbing finds in Australia.
03:08In 1971, the site belonged to a farmer who cultivated zucchini and potatoes.
03:14As the farmer tried to expand his farm,
03:17he kept hitting large rocks in his fields as he worked.
03:21Looking closer at the rocks on his path,
03:24he found marine fossils and strange craters.
03:28The farmer passed on his findings to geology professors who began to study the formations.
03:34When geologists began to dig in the region,
03:37they discovered a huge layer of chalk and ochre that was covered with craters.
03:42There were 35 craters in total,
03:44and the age of the rock layer was estimated at about 25 million years.
03:49Scientists studying this mystery believe that hot springs,
03:52ancient oceanic activity and meteorites
03:55are responsible for the formation of these craters,
03:58and we would like to know the people who gave these cities the names Bundaberg and Djin Djin.
04:04The dental machine is a kind of old computer
04:07that still disconcerts scientists with its extraordinary design.
04:11About 2,000 years ago, a Greek ship sank off the island of Antikythera.
04:16The wreck was discovered in 1900,
04:18and divers recovered some of its old artefacts.
04:22When archaeologists began to sort the wreck's finds,
04:25they came across an object that didn't seem to correspond to anything known at the time.
04:30The wreck was old,
04:32but they found an incredible device that seemed to be far too advanced technologically.
04:37The machine operated like a calculator,
04:39allowing its user to track with astonishing precision
04:43the time, the movement of the stars, the eclipses, the phases of the Moon,
04:48and even a countdown for events such as the Olympic Games.
04:51This level of technology is almost impossible to explain for a wreck of ancient Greece.
04:57No mechanism even came close to such a machine before the 14th century,
05:02when clocks with gears began to be manufactured in Europe.
05:06How was such a device created so long ago,
05:101,400 years ahead of its time?
05:13The wreck of Antikythera and the loss of the calculator
05:16could it have delayed our technological development by several hundred years?
05:21Meanwhile, the mountains of the Caucasus, bordering the Black Sea,
05:24are one of the rare regions of Europe that has not been affected significantly by humans,
05:29even though the term Caucasian refers to most people with white skin.
05:34Archaeologists have found many ancient megalithic structures in the region.
05:39These structures, similar to houses, commonly known as dolmens,
05:43contain jewels, bronze tools, and various potteries.
05:47Archaeologists do not know who built them, nor why, nor for what purpose.
05:52The structures are either two stones held together by a large stone made up of roofs,
05:57or smaller stones stacked like a wall with a hole on one side.
06:02We even found stone caps to seal what was inside.
06:06What is even stranger with these formations,
06:09is that they are not only found in the Caucasus.
06:12They can be found all over the world, in Australia, South Korea,
06:15Colombia, Africa, and even in France.
06:19Their function remains unknown, which opens the way to multiple hypotheses.
06:24The discovery of the tomb of the first emperor of China in 1974 is well documented.
06:29Who could forget the discovery of 8,000 warriors in burnt earth protecting his entrance?
06:34Most of the statues are of warriors, each with a unique facial expression.
06:39There are even horses and chariots in burnt earth,
06:42just in case.
06:45What we do not know is that we have not yet entered certain areas of the tomb.
06:50In 2008, NASA asked itself an intriguing question.
06:53How do spiders build their webs in weightlessness?
06:57It sent two spiders to the International Space Station.
07:01The first was the main participant,
07:03and the second would replace the first in case it had a problem.
07:07However, things did not go as planned.
07:10The rescue spider managed to escape and paid a visit to its companion,
07:14which led to a certain disorder.
07:16They built webbed webs that interfered with each other.
07:20As if that were not enough, the flies supposed to serve them food
07:23began to reproduce faster than expected.
07:26Their larvae escaped their container and covered the window in front of the compartment.
07:30Very quickly, the spiders found themselves completely hidden behind the larvae.
07:34Although this first experiment did not go well,
07:37one of the researchers involved in its organization was still curious.
07:41In 2011, she had the opportunity to repeat the experiment.
07:45This time, she asked for the help of other researchers.
07:48They decided to send a different kind of spider into space
07:52and prepared four specimens,
07:54two for the ISS and two for Earth,
07:57in order to be able to compare the results.
07:59The goal was to expose the spiders to variable gravity conditions
08:03and observe their behavior.
08:05However, there was another twist in the story.
08:09At first, they thought they had four female spiders,
08:12but it turned out that two of them were males.
08:15Determining the sex of young spiders can be tricky,
08:18but fortunately, one male had already been sent into space
08:22while the other remained on Earth,
08:24which allowed them to collect precious data.
08:27The second experiment turned out to be fruitful.
08:30The spiders were inactive.
08:32They built and dismantled a star,
08:34and even without the help of gravity,
08:36they were weaving new ones.
08:38Three cameras were able to take thousands of photos,
08:40showing their intense work on the star.
08:43Interestingly, spiders seem to create stars
08:46much more symmetrical in space than on Earth.
08:49The center of the stars is closer to the middle,
08:52and, surprisingly, spiders do not always position their heads down,
08:56as they usually do on Earth.
08:59However, an important factor made all the difference.
09:02Light.
09:04When the spiders of the ISS had a light source,
09:08they weaved asymmetrical stars,
09:10similar to the ones we find here.
09:13Light played a crucial role in the orientation of the spiders.
09:16The lamps in the compartment were fixed at the top.
09:19If the lamps had been positioned differently,
09:22for example on the side,
09:24it would have been difficult to observe the effect of light
09:27on the symmetry of the stars.
09:29When the lamps were turned off,
09:31the spiders rested in random orientations on their web.
09:35However, once the lights were on,
09:37they oriented themselves to the opposite of the light source,
09:40that is, down.
09:42Thus, in the absence of gravity,
09:44light helped them to orient themselves.
09:46This discovery was unexpected,
09:48because spiders can generally build their web in the dark
09:52and effectively capture their prey, even without light.
09:55Wow, there is a hole at the bottom of the ocean.
09:58It would seem that the ocean is a leak.
10:01But it is not a leak as we might expect,
10:04where the water simply flows.
10:06It is rather a source,
10:08because the water flows inward and not outward.
10:11This unique leak is known as the Piti Oasis.
10:14It is a student named Brendan Phillip
10:16who discovered it by chance
10:18when he noticed that bubbles were rising to the surface.
10:21Normally, the presence of bubbles in the ocean
10:23indicates that there could be hydrothermal chimneys,
10:26which are hot spots where very interesting phenomena develop.
10:29These vents are in fact comparable to hot springs
10:32along the ocean floor.
10:34But instead of boiling at the bottom of the seas,
10:36they release a fluid overheated in the crust of our planet.
10:39When the sea water infiltrates these cracks
10:42and sinks into the crust,
10:44it comes into contact with the extremely hot mantle of our planet.
10:47The sea water is then carried to very high temperatures.
10:51Then, by rising to the surface,
10:53it transports dissolved gases and minerals.
10:56When the hot fluid spills out of the chimneys,
10:58it mixes with the surrounding sea water
11:00and cools down quickly.
11:02At a short distance from the chimney,
11:04the temperature can drop to a comfortable 20°C.
11:08Which is exactly, it seems,
11:10what some creatures appreciate.
11:13And there are real oddities that live in this darkness.
11:16Like ghostly fish,
11:18giant red-pointed tubiculars,
11:20and a unique type of shrimp with eyes on its back.
11:23Some of these creatures,
11:25like tubiculars and bacteria,
11:28depend on the chemical compounds and minerals released by the chimneys
11:31to survive in these difficult conditions.
11:34But in this case,
11:35the boiling water did not come from a hydrothermal chimney.
11:38It came from a source,
11:40and that's a little more worrying.
11:42The water from this reservoir must stay where it is.
11:45If too much of it escapes,
11:47it could have serious consequences,
11:49especially for the surrounding region.
11:52We can observe this unusual leak
11:54along the subduction zone of Cascadia,
11:56which is a huge fault
11:58off the northwest coast of the Pacific.
12:00It is a place where two large plates
12:02that form the earth's crust meet
12:04and slide against each other.
12:06The oasis water somehow acts
12:08like a lubricant between these plates.
12:10We can compare the fault zone
12:12to a pneumatic hockey table.
12:14When the fluid pressure is high,
12:16it is as if the air was activated.
12:18This means that the friction between the plates is reduced,
12:21which allows the latter to move.
12:24But if the fluid pressure is lower,
12:26the two plates can get stuck against each other,
12:29which leads to an accumulation of the constraint.
12:32So they feel bad.
12:34In the context of tectonic plates,
12:36the constraint is a pressure or a force
12:38capable of causing a deformation.
12:40And if this pressure starts to accumulate,
12:42at some point,
12:45when it is too strong,
12:47it can trigger earthquakes,
12:49and probably no less.
12:51For example, a release of the constraint
12:54in the subduction zone of Cascadia
12:56could lead to an earthquake
12:58of magnitude 9.
13:00For comparison,
13:01the largest earthquake ever recorded
13:03occurred in Chile in 1960,
13:06with a magnitude of 9.5.
13:08The damage was colossal.
13:10We hope that the water will remain in its reservoir
13:13and will continue to maintain the delicate balance
13:15between the tectonic plates.
13:17We have explored only 5% of the oceans.
13:20Who knows how many great things
13:22are still at the bottom,
13:24waiting to be discovered?
13:26Look, for example,
13:27these mysterious holes that scientists
13:29have discovered in the depths of the Atlantic Ocean,
13:32near the Azores.
13:33They are perfectly aligned
13:35and spaced about 10 cm,
13:37or even a few meters in some CAs.
13:40They look like punch holes
13:42left by a sewing machine.
13:44Some think these holes
13:45could have a biological origin.
13:47For example,
13:48some fish could have formed them
13:50by walking on the seabed.
13:52Others think that we are in the presence
13:54of a phenomenon of human origin,
13:56perhaps left by a studded tire.
13:58Of course, such holes are perfect
14:00to invent stories about creatures
14:02from other planets
14:03that could have created them.
14:05Or maybe even legendary monsters,
14:07like that of Loch Ness.
14:09It is difficult to explain
14:11the symmetry of these holes,
14:13but a specialist biologist
14:15from the depths has proposed
14:17a rather convincing explanation.
14:19According to him,
14:20it could be an animal
14:21digging under the sediments.
14:23And from time to time,
14:24he could create small chimneys
14:26just to have access
14:27to a circulation of clean water
14:29in his small terrier.
14:30There are lots of sediments
14:31around the openings of each hole,
14:33and he confirms the idea
14:34that something pushed the ground
14:35down below.
