How are these stones cut and machined?

[walker]

they have elephants who can lift that

and drilling oh well, i duno. lol.. maybe they have some tools.

what kind of elephant can lift 800 tons? so far, there are no mastodon fossils found in bolivia.

No one exactly knows the answer at the moment. It can range from molding (an ancient form of concrete), or plain and simple uncanny accuracy in the hands of those ancient masons.

the material is granite and diorite not a form of concrete.

mention of "uncanny accuracy" of ancient masons unmatched by modern skills yet.

lets stick to the topic rod. .. and squeeze whatever science flavored juices we can to try to figure out answers about this huge blocks of heavy granite.

mod warnings considered.

ma cut rman ni grinder cutter blade

how did they power those ancient grinders? they had ancient electricity?

[entrepreneur101]

solar power cguro haha
bitaw hantud karn wala pa gyud na nila matubag
so pa buta bungol lng sa ta ani gud

i heard a lecture by author john hancock that puma puncu in bolivia is more unexplainable than anything of the ancient sites primarily because of the way these stones were cut, polished and fitted like a giant lego puzzle.

well, he is not considered a scientist by the normal definition but he is known for his meticulous research of facts.

Maybe this stone, during the ancient time is not as hard as when they (people) made it. As time pass by, this has been harden in proportion sa time.

ancient time or modern time, the stone is already identified as GRANITE and DIORITE.

siguro nakahimo sila ug tools nga mao ila gigamit at the same time they have all the time they need so hinay2x lang nila na gibuhat IMO

kita ko sa usa ka series ani, usa sa ilang explanation is ilang gi mold ang mga rock through intense heat nga malanay na ang bato, pero dili ko contented sa ilang explanation.

Granite and diorite are examples of nature's hardest materials. I've read before that it is possible to carve or make a cut on these "hard stones" in the modern times with a technology such as ultrasonic machining. The stones mentioned are quite very old. The people working on it may have acquired their own crude version of ultrasonic like machining but quite effective. The indentations are quite amazing on the photos.

superb.its really amazing how these people managed to do this.it must have been a pretty tough job to do.

[-==ahylingel==-]

i saw the documentary... they think it has somehow to do with aliens..

daghan pa kaayo mga rock formations nga unexplained on how it was brought there etc...

[jofer]

yeah but lets not entertain that idea here.this thread might be closed or is on its way to be.hehe

[Inta]

they are done by ANCIENT ALIENS
