There are quite a few rust free iron pillars in India. Western world knows only about the one in Delhi. To say they were made by accident would be under statement and undermining their knowledge of metallurgy

my mate is a blacksmith and he said that Damascas steel is made with 'heart', referencing the amount of effort needed to create it. Certainly not just poured from the crucible.

Roman concrete’s secret ingredient is volcanic ash and it was also a highly protected trade secret during it’s day. The relative scarcity of volcanic ash does not allow roman concrete to scale like portland cement.

Humans 5 or ever 10 thousand years ago were essentially no different mentaly or physically than modern man. They had the same mind, the same inventiveness, the same sense of humour and hopes and desires, the only difference was the technology and knowledge they had access to. Presented with a problem, they would find ways to solve it using what was available to them. Who knows, maybe the "softened rock" was just stone masons having a joke with the locals, or showing off their skills to their colleagues.

That bicycle (or scooter) could easily have been made out of bamboo. It's a very efficient shape for driving so why do we say it was invented so recently? That's just weird to say that the ancients could not have thought of that design. And none of them would be in archeological digs today.

Hint: The more advanced a technology, the more frequent and in-depth maintenance/repair it requires to remain functional. If for "some reason" the people disappeared from our civilization, the vast majority of our works would disintegrate in about 200 years. Worse, if they didn't disappear but were no longer interested and/or able to repair the advanced stuff, historically speaking that stuff always gets looted and broken up for raw materials in short order. This is saying, if ancient civilizations past a certain point were MORE advanced than us, we'd have no way of knowing, and this relatively recently, ranging from 1,000 to 5,000 years ago depending on where on earth. Their tech would be dust, their structures would be stripped, scavenged, and leveled more often than not.

Ancient man was waaaaayyyy more intelligent than most people, even scientists, give them credit for.

Hey, simple answer to the "melted" stone. It's hard to melt stone, so what if the answer is simpler than that? It was never melted, but it was liquid at one point. Someone could have made a concrete mix out of nearby materials. It would have been soft at one point, soft enough to leave hands prints, but then hardened to where it is.

A lot of ancient tech like the pillar thing can be summed up as: they figured something out by accident, they know it works, but they don't know why it works. They keep doing it despite not knowing how it works.

I recently went to Weymouth's Jurrasic Coast in South West England. It is mind blowing to see big chunks of the cliff broken off, because you can see many sets of footprints imprinted in the sandstone.

I question the accuracy of some of the information presented in this…

Most examples of historic concrete are well known and studied by at least some people in Building Research Centre in England. I attended a lecture by one of them in 1979. Examples go back 5000 years. The harbour at Ostia Antica is well known and some modern concrete is just as durable. If you visit the Pantheon in Rome you can see how durable concrete can be. The structure is fine condition.

Pls check your facts, there are four more (same)rust proof pillars in India built during the same period.

And that Marquette thing was definitely used for angles and leveling. We still use things similar in design today. Seems like an extremely inefficient way to tell time. But very useful in masonry and framing

Caves have been used for hundreds of years to keep food cool. In places where people lived near caves. As well as streams. My grandmother said they had... I think she called it a "spring race" where they kept their food in crocks in the spring to keep it cool when she was growing up. Like dairy foods. Things that weren't smoked, salted, pickled, or like jams and jellies. Other people had spring houses for the same purpose.

We really are a species with amnesia, none of this stuff is taught in the mainstream.

I’m a bricklayer and this is awesome history of masonry. 👍

Showing someone from 1000 years ago your mobile phone: "That's pretty, what's it do?" "I can talk to people far away with it... or I could if they had one, too. And there were any cell towers nearby. And if you had a USB port I could recharge at. But look! It's shiny. BTW, how do you make bread?"

That plant mixture is the first explanation I've ever heard for ancient peruvian megalithic sites.

Ever look up the wonders of time videos, one man embedded his footprints inches deep into solid stone just by walking the steps repeatedly no softening agent required.

Why do mainstream academics try harder to debunk mysteries than to actually study them.

In case anyone was wondering @ 2:56 that particular cell phone is the 1995 Motorola Flare. Just an interesting piece of side information. 😁

Of course softening stone is compelling. However, moving such massive weights is not going to be facilitated by softening.

Damascus steel is not formed in a crucible but by layering different types of steel and forging them together..

This man's over here talking about bicycle carvings on that temple and I'm over here wondering why he isn't saying a word about the carvings of cell phones nearby.

The bicycle carving was definitely a modern addition. The dead giveaway is that it's an exact replica of a modern bike. If it was some ancient lost tech, it would certainly look different in some respects (handle bars, wheel/spoke, etc).

The bike was interesting but the cell phone next to it was cooler imo

What were all those rust colored patches on the rust-proof iron pillar in the first segment at 1:23? I understand that it is ancient and not rusting away, but narrator said it is completely rust free and it just looks like there is surface rust to me

You probably have to use saltwater to mix the concrete vs just letting salt water absorb into your already dry crete

It wasn't the Inca, The polygonol stone work was there before they arrived. They merely adapted the building style and you can see by the crude cuts on top of the existing Building structure, including filling walls with loose gravel etc. The walls that were there are noit feeble and are completely solid. So no. It was not the INCA.

9:56 Did we really have to bring racism into it?

BROTHER, YOU ARE THE BEST!!! You oooh really helped me!! THANK YOU VERY MUCH!

PLease cite a reference to where I can find a functional description of an Egyptian marquette, I want to find out how it worked.

Too many factual untruths in this one...

Nicely done. These are fascinating.

The rust proof pillar wasn't an accident.. the recipe for the same is written down in our ancient books.. it was called as vajra dhatu. It had lead,brass and one other substances with the exact proportion..

"tHaT wAs RaCiSt" Oof...

This was like a comic book edition of How It's Made.

Modern cement falls apart after about 100 years BECAUSE of the use of rebar. Without the rebar, the cement would last just as long as the cement from ancient Rome. The rebar rusts inside the cement over time. When the iron rusts, it expands. The expanding rust causes the cement to crack and spall.

Keep your opinions out of the videos

well not true we can get the ancient roman concrete mixture right granted we only rediscovered the correct formula for roman concrete 5 or 6 years ago (officially at least) the problem is that it's simply not economically viable for large-scale production as the materials required are highly localized. And are extremely expensive to get in high enough quantities. When modern concrete doesn't last as long but is 20 times easier and cheaper to mass-produce and doesn't necessarily need to last as long since we have other construction materials and building methods that we use when we need something to last a long time.

crucible steel for weapons is forged not cast, there may be an exception somewhere in history, but forging is the norm. pretty sure steel swords are not cast. iron maybe, definitely bronze is cast.

The stone softeners did it for a specific purpose that is to make their buildings , but I'll bet that they knew that the process would be lost in time .. they made puzzles to confound the future and died laughing their ass off knowing how it would screw with the people in the future.....

They didn't include the Valerian steel made from the blood of dragons

"AnD tHeYrE RaCiSt!!"

Don’t know how these are abandoned techs when people are still using them

👏 really loved this.

Damascus steel was made in Damascus Syria using indian Wootz steel as raw material. The Syrians would work the indian steel folding it multiple times introducing carbon in the folds increasing its ductility and strength. The crusaders faced the formidable swords made with Damascus steel and was one reason for their defeat.

Bicycles were invented in 1817, the nineteenth century not eighteenth century!

"you will be able to blow their minds with technology" Me being accused by my ancient ancestor as a witch

This is one of the first videos that gets Damascus right. Most people confuse it with the Japanese honzo style of folding steel when in fact it is a molten pour technique. Good on ya👍

"Unexplained" does NOT mean magical, no matter what your mommy told you. Stay strong, people!

Damascus steel have seen had been folded over & over....ect. Lots of work! It aligns the carbon atoms in layers.

that bike though at 2:38 its a weird ass design i havent seen one like that ever. but look at the frame going from the back wheel to the seat area. 2 tubes are cut in half and joined. cleanly you can see the individual tubes. did they have bolts and nuts with threads? could they weld? not many other ways especially the wheels. whats the bearing?

I'll give a like specifically for having the yakchal.

Simply amazing

I was thinking something similar today about travel. Instead of rich people who can afford to take time off of work and fly to places far away to see folks who are impoverish. Why don’t we make local programs where we offer to host a family in our home town for a week or weekend? Turn the idea of a vacation upside down and let the people Who really do deserve a break and might not have any other chance for cultural exploration to do so

The reason for all this is explained in the documentary "land of the lost" Dr Rick Marshall will demonstrate without a shadow of a doubt, how today's knowledge can exist in the past, present, and future simultaneously with the use of tachyon rays.

Ancestor sees smart watch...."Slay him for food!"

wow that's interesting 💙💙💙

Whoa, whoa, whoa there, don't go throwing the R-word around all willy-nilly like there, cowboy. We're talking about science and history, no room for that word in those domains.

Page 5:00 no they did not know a way to soften stone. Only that the substance we call stone today started clay like texture can be sculpted by wooden tools. It turn into stone hard over time under the sun.

Thx 👏👍

Loved the bicycle graffiti. all of this is very interesting.

nobody's gonna talk about the guy pouring ice out of a bottle of water onto the sand ? we're just gonna gloss over that

Damascus steel is NOT made via crucible. It is produced by folding and forging different toughness steels together, creating hard but flexible steel.

Please make a vedio on Harappa and Mohenjodaro located at Indus valley.

The bicycle carvings were clearly added later , it was most likely added because the invention of the bicycle was so beneficial for humans that they felt the need to honor it. The cultures in that part of the world tends to worship and glorify anything that help them throughout history. Like the cow!

I clearly saw rust on the iron rod. Someone is doing something to it to keep the rust off.

It's not stone softening. It's just high tech clay

Oh yeah, the famous Romans and their buildings. A shabby Cesar's house in the heart of the Empire and a magnificent temple in Baalbek, modern day Lebanon. Perfectly logical.

wootz steel isnt demascus. wootz steel comes from what is now india where it was made in a similar style to crucible steel. damascus comes from; pause for dramatic effect, Damascus. damascus is also layered and folded steel billits that are forgewelded together.

6:50 WRONG! It's forged steel. Never heated high enough to melt into a mold but only hot enough to weld the different peices of iron together with the help of an iron hammer 🔨 💪 and sweat! All the while working in carbon to form a stronger and more flexible steel. Forged not Cast.

"Arrogant and racist." Okay dude

As for Roman concrete, we can reproduce it. However it reacts poorly when reinforcing it with metal. Thus we can't use it for skyscrapers.

Take a shot for each time "Ancient Ancestors" was used

Our ancestors laugh at those who think they were little more than monkeys with sticks. Can't see the truth in front of our faces. 'Then why is it only stone?' Because over the millennia everything decays, stone with arguably the longest longevity. The plastic and whatever else in a circuit board will return to the earth no matter what they tell you. The metal in said circuit board will too, eventually. Can't wait until they find a circuit board from ancient times preserved in the right conditions. Won't that set the 'ologists of the past off???

The photo that shows the scoop marks like claws dug it out, is from very long ago. So long ago that the present hard rock was soft and like soft mud. Over time they petrified. So it takes centuries of a million times to accomplish this , the history of the planet is up for review.

2:04 that bicycle carving is not done 2000 years ago.

6:23 wootz steel and damacus steel are not the same thing. Damacus steel was so good because it was crucible steel, which was new at the time. Wootz steel is any layer steel, and it is not better than standard steel.

Wasn't a large vat of mercury found under a meso American pyramid? Mercury has been used to soften stone.

How is the Substanz spelld für the Iron piller i would like to read up on this but i cant finde it ?

What a fine idea that was 🙏

Wootz steel Damascus steel and crucible ar all completely different. A little research on your end would be greatly appreciated.

we as modern civilizations seem far more primitive than our ancestors. Not only were they able to master technologies beyond our comprehension, but also managed to do so in harmony with nature, which goes to show that nature and technology can go hand in hand...

I think the answer is in the Bible...the 'softened' stone was from thickened mud after the flood...before it hardened to stone...( in Sumarian text is is said that AFTER THE FLOOD 6 SUNS APPEARED IN THE SKY...)(TO HARDEN THE MUD TO STONE...AS A KILN WOULD DO WITH SLIP.)

The book by Jonathan Grey called Dead Men's Secrets has many of these examples

You need to learn what the actual meaning is of the word “racist”…it is not at all racist to think a group of primitive people were primitive…

"they assumed the Spanish created these aquifers in the region, and that is racist" Everything is racist

How about Coral Castle in Homestead Florida? I visited this place…no one knows how this ninety eight pound man cut,mrsised and built these thirty ton slabs of coral, check it out!

This iron pole physically cannot rust! *shows closeup photos of rusty pole*

You said it was racist to assume that the Spanish had to have built them because they were believed to be too primitive. That's not racist. You're dangerous.

The stone softing was something that needed to be maintained over the years. When it wasn't it got hard. The rocks were probably kept wet and used for pottery

Subscribed... 👽

Pretty interesting

Damascus steel was never melted it's basically bunch of small metal pieces inside steel cube that was then heated and hammered into a blade which made the metal pieces squished and longered then when they sharpend the knife and remove the steel cube walls the texture of the squished metal pieces was reviled Also the strength comes from the bunch of metal pieces fused together so the damage won't progress as much as on solid steel sword

Very few extinctions have been human-driven. In total, less than 0.1%. As well, plants and animals change in form over time and a minute change in biochemistry can easily alter the effects produced by their by-products.

5:46 Where and when is that stone from ?? Interesting how some bits look new.

At 20:46 what about the cell phone or radio a little pricey isn't it check it out right hand side

I dont see how it's racist to assume that a people who never invented the wheel would be too primitive to invent those water cashes
