Is this How Ancient Megalithic Structures Were Made? MIT Scientist Move 25-Ton Blocks by Hand!

Print

Ancient cultures in Peru, China and Egypt, to name only a few; quarried, lifted, transported and crafted vast megaliths, some weighing several hundred tons. Until now, theories as to how these stones were moved in prehistory have been abundant, but demonstrations in the field have been thin on the ground. However, a highly-creative experiment by a team of MIT researchers is now revealing our forebears as masters of gravity, balance and leverage.

The team of scientists released a video on Vimeo showing 25-ton cement blocks being pushed by two men effortlessly with one hand, and this is no internet stunt. On the contrary, the blocks can be pivoted, rocked, walked, tilted or rolled with almost no physical exertion required to achieve what a Gizmodo article rightfully referred to as “remarkable ease and precision.”

The man behind the magic is Brandon Clifford, an assistant professor at MIT and co-founder of Matter Design , who together with building material specialist CEMEX, designed sets of over-sized concrete monolithic building blocks which interlinked to form lager structures. You might already have noticed how similar in style these cement blocks are to the massive boulders that were used to build Sacsayhuamán, the vast fortified citadel situated on the northern outskirts of the city of Cusco, Peru, the historic capital of the Inca Empire.

What Is the Science Behind The ‘Weightless’ Illusion?

There are several design dynamics at play here, which it has to be said, gives the MIT team infinite advantages over their ancient counterparts. For one, the scientists have total control over every microcosmic and macrocosmic aspect of their media - the blocks. The concrete masses are referred to by the scientists as “massive masonry units” (MMUs) and are made with “varying densities to allow precise control over where the object’s center of gravity ends up, adding stability and balance,” according to the Gizmodo article.

While each MMU appears to have been randomly generated, the Matter Design website tell us that each one is carefully engineered with “strategically placed bevels, rounded edges, pivot points, handles, and interlocking features.”

On the other hand, ancient Peruvians transported their massive stones across vast distances in unpredictable outdoor conditions.

The Future of Ancient Sciences

One of the main reasons this interesting experiment has come from ‘Matter Design’ is because they operate much in the same way that ancient cultures did. By this, I mean that the team is multi-disciplined with a wide-ranging skill set, and when focused on a common problem like ‘how do were move this hellishly-sized stone?’ mountains can almost be moved! Sort of, you know what I mean.

And just like on an ancient Andean farm or an Egyptian wheat field, where proto-scientists gauged environmental conditions while shamans and priests dealt with the gods, Matter Design is, in their own words, “a synthesis of art and science,” a design studio and a research lab. Collaborating with industrial partners, historians, music composers and visual artists they “identify ancient knowledge” and unearth “abandoned knowledge” that they claim resonates with topics of today.

This reawakening of ancient thinking processes is going to do more than add to our understanding of how the ancient world was built; these advances might also help in places prone to flooding as the nimble concrete walls could be assembled by local residents and services.

The technology may also have applications where the blocks could be used to quickly form impenetrable barricades within military situations, to defend from attack; just like the Incas used their interlocking stones 1500 years ago.

I am sorry, but those blocks DO NOT look like they weigh 25 tons. Also one thing is to roll them around and ANOTHER is to lift them several feet in the air.
According to that video it seems easy to roll them around in a LIMITED area, BUT transporting them over long distances???

The technique described here may have worked for the first layer. Subsequent layers have flat bottoms
so how were they set in place?

Has the question arieen, why did the ancients need structures built so? What were the buildings and walls built for and against?

Could it have been the Megafauna before the Dryas event?

Any substantive research dating the different megalithic structures about the world?

So the ancient Proto-Incans quarried some of the hardest stone (short of diamonds) and transported it some distance to Sacsayhuaman, then carefully modeled it with computer precision to fit together in thousands of feet of zig zag walls 18 to 20 feet tall. Sure! Sounds reasonable...wink, winkn nudge, nudge.

The Incas of 1500 years ago didn't put together interlocking stones 1500 years ago. The Denovisians were able to do this... If you look at structures near the Denovisian caves in Siberia, they are the same...and there is evidence they traveled to this part of the world. But thay was over 12000 years ago. If the Incas were capable of building these walls, they would have fared better against the Spanish.
