There are many things that science is still unable to explain it , and today We will talking about the top 10 OLDEST Technologies That Scientists Can't Explain.
10-Greek fire
Ancient scientists have given countless inventions to humanity some inventions from ancient times still, remain a mystery though the Greek fire used by the Byzantine Empire in the seventh century is one of the biggest secrets in science this was a liquid substance thrown from ships it was impossible to extinguish with water and it spread quickly this substance helped to defeat enemies in many naval battles, in fact, it has served an inspiration for the famous wildfire on the series Game of Thrones National Geographic got closer to making this fire by the creation of a flamethrower built with a brass tube and a mixture of oil and pine resin however there is a belief that the Greek fire contained naphtha sulphur and ammonia among other substances the components of the Greek fire were a well-kept secret nowadays historians and chemists continue to look for the way to reproduce the formula of the Greek fire that seems to have lost in time.
9-Damascus steel
The Christian soldiers who fought in the Crusades came across a type of weapon that had never been seen before the swords carried by the Islamic military were constructed with the Damascus steel the strength flexibility and wave-like patterns made them completely unique it is a fact that they could cut a still prevail in the air and they could slice a rock without damaging the blade sharpness these swords were made of crucial steel meaning steel made with a different heating and cooling techniques moreover, they were made with a mixture of iron mineral wood leaves and coal however, the specifications for making these swords disappeared when the last blacksmiths who made them died in the year 1700 competence universe stay in Madrid Spain states that they have unveiled the secret to make these swords in fact, they have the patent to forge steel swords with a high content of carbon nevertheless there are still debates by experts in metallurgy about the real manufacturing of Damascus steel.
8-The Voynich manuscript
Wilfrid Voynich a Lithuanian antiquarian of Polish origin got a manuscript by an anonymous author the content of this manuscript is still, unknown Voynich spent his life trying to find out the secrets of the document the book known as the Voynich manuscript honoring voyages name has 246 pages and it is written in an alphabet that nobody has been able to identify it is an undecipherable language in 2009 carbon dating technique was performed on this manuscript hence it found out that the manuscript was from the 15th century this manuscript has hundreds of drawings that allow dividing the content of it into sections such as botany biology and astrology it also has miniatures of naked women and water or walking in the water and they are interacting by means of tubes or capsules these miniatures are very strange considering the age of the document it has become the most researched puzzle that has to be solved.
7-The Antikythera mechanism
This corded brass object that seems useless is actually a 2,000 years old analog computer the Antikythera mechanism was recovered from the bottom of the sea in 1901 near Antikythera island greece it is divided into 82 pieces the device is a complex clock mechanism system made up of many brass gears antiques experts have found out that this system was used to calculate the moon phases and the lunisolar calendar it could also forecast eclipses and be used to plan the exact date of the Panhellenic games such as Olympic at critical games moreover it was also used to show the planet movements known by that time to study its mechanism a special tomograph built for the investigation of this ancient object the similar technology was not developed until the Scientific Revolution between the 16th and 17th centuries so it's a real mystery to know who made this device and how its creator got the necessary knowledge to make a futuristic invention at that time.
6-Shang hang seismograph
Present-day seismographs have nothing to do with the first earthquake detector in history Zhang hang a Chinese scientist and an astronomer from the East Han Dynasty this seismoscope in the year 132 ad it is a copper vessel with dragon heads aiming at the cardinal points beneath the dragon heads there are various toads with open mouths when there was an earthquake a bronze bar fell into one of the toads mouth indicating where the earthquake had taken place and this device is able to detect earthquakes occurring 600 kilometers away some theorists believe that it is a system based on a free swinging pendulum driven by inertia, however, the operation of this device is one of the biggest mysteries in history the original seismograph does not exist anymore and most of its replications are used just for decoration there is a functional replica of this device in the History Museum in Beijing.
5-Ulfberht Sword
Many tombs from the Viking Age have been discovered all over the north of Europe archaeologists have found inside the tombs a total of 171 Ulfberht Sword, these swords were made with techniques that were very advanced for that age they got their name from the inscription plus Ulfberht on their blades the meaning of this word is still unknown these swords are made of 99.9% pure metal which was free from slag also having an almost perfect carbon balance according to experts the technology to make these swords was superior at that time this technology did not appear but 800 years later in other regions it is similar to the one used for making Damascus steel in 2014 a 9th-century tomb was found in Scandinavia this tomb had an Islamic inscription this finding makes scientists think that there may be a link between Viking swords and the weapons used centuries later by the Arabian militaries in the Crusades however no evidence has validated this coincidence.
4-The iron pillar of Delhi
Time is a deadly enemy of ancient monuments that causes maximum damage that's why this iron pillar weighing 6 tons and 7.21 meters high which is not rusted during more than 1600 years it is still an engineering mystery located in Delhi India the only clue about its origin is the inscriptions on the metal they can be perfectly seen after centuries of exposure to the natural environment many scientists think that the mild weather in the area does not affect this big iron mass others suggest that phosphorus is a component of the pillar and there is no sulphide and manganese in its structure which could contribute to the good condition of the monument however all scientists agree that this big iron monument is a living testimony of the wisdom of India's former inhabitants.
3-The Phaistos Disc
Luigi Pernier, an Italian archaeologists discovered the fastest disc on the Greek island of Crete in 1908 this disc also known as the rosetta stone of the Minoan civilization and made from baked clay is 15 centimetres in diameter and dates back to the late Minoan Bronze Age it is engraved on both sides with a spiral of 242 symbols the real meanings of these symbols are still unknown there are some theories about the symbols they seem to be printed with a kind of seal this fact makes historians think that this is probably one of the oldest printed documents in existence or this object might have been used as a seal itself and may be considered the first printing attempt it is also believed that this disc was a musical score or even an asset inventory a calendar or a game a true thing is that present time experts consider it a jigsaw puzzle.
2-Roman dodecahedron
Despite the fact, Roman civilization has been studied for centuries still it is full of mysteries one of those mysteries is the Roman dodecahedron it dates back 200 years and it is a hollow object with 12 sides made up of brass or stone each side has a pentagonal shape and a hole in the center hundreds of these devices have been found from Wales too hungry especially in Germany France and Italy its size varies between 4 centimeters to 11 centimeters however no document has information about its existence or purpose this is weird considering that Roman civilization kept the records of almost everything there is a belief that these dodecahedron were used as candle holders dice gauges for water pipes or simply as a solid foundation to support the Roman eagle symbol it is also possible to think that these objects were used for religious purposes or fortune-telling there is no doubt that this is a multi-purpose mysterious object.
1-Giant stone spheres
More than 500 pre-columbian stone spheres were discovered in the Sierpe district, in the south of Costa Rica in 1939 the size of the stones ranges from 30 to 257 and they weigh between two kilos and 16 tonnes it was concluded that Costa Rica's indigenous people used advanced cutting and polishing techniques to transform blocks gia rites and igneous rock into spheres of the perfect finish moreover, it is believed that a superior method to transport these spheres was also used experts state that these spheres are a mystery not because of their construction but because of what they represent nobody has figured it out yet many of these stones have been moved or exploited by treasure hunters this situation has become an obstacle for investigation some of these stones were placed near human and animal statues few data suggests that this group of rocks my been used as an astronomical calendar but the only truth is that there are not spheres like these in any other place on this planet.
