I'm not allowed any more to tell you where you are going .
But I can tell you where you have been .
Stretching for 3000 km across Southern Africa.
These are not ruins that can simply be wished away . They stretch on kilometer by kilometer . The estimate for one city is 651 billion tonnes of stone . Not a trivial exercise .
See "Temples" by Tellinger and Heine ISBN13: 978-1-920153-08-3
The aerial photographs are incontestable . It is real .
This I heard myself . A stone being whacked and giving forth a sweet , monotone frequency that decreases in intensity but not frequency .
Another incontestable . Ding-an-sich.
These are sensitive to external sound-harmonics . Internal spikes where muscles , nerves and sinews attach will heat up drastically . Crop-eating insects were sensitive to certain frequencies .
Some unsung genius noticed , while whacking one river stone against another , that the thingie gave out a sound and certain insects fled the area .
They then amplified the effect with very circular stonewalls , with no mortar .
Somebody walked around the inner circle whacking the stones , setting up a standing wave .
It is important to notice that the wall was not mortared . The gaps allowed the sound waves to escape . About 1/3 of the sound waves was broadcast over the landscape . These chased away the insects .
The walls were 1/3 porous to sound .
Some frequencies would considerably enhance nitrogen fixation .
Like fertilizer .
You ended up with circular stone sound generators as both insecticides and fertilizers
From the evidence , it was quite effective . Circular sound structures were surrounded by irregular stone fences , mostly to keep herbivores out .
Sound waves irradiated surrounding fields
This was not agriculture . It was more akin to the farming in pre-Spanish California .
They did not plough or plant , but productivity in terms of grasses was very high .Grazing animals were used to harvest . The energy relations are very simple given a low insect population .
The population density was very high , About the same as present .
They ended up in a typical Malthusian fix .
There is no evidence of war ,.
The rainfall decreased (see http://andreswhy.blogspot.com "Magadigadi sea"
Overpopulated areas died down (as happened in the Middle East circa1000 AD)
Thousands and thousands of kilometers of dwellings were gradually abandoned .
I know that humans prefer a catastrophic end , but a whimper is usually the end of stupidity .
They overpopulated , the rainfall decreased , the food decreased , and the remaining population simply went back to subsistence farming , abandoning civilization .
So much for that .
