@BrightInsight6 Nubs tend to occur on blocks with maximum formwork constraint: windows, doorways, corners.
They are at the bottom edge of a block precisely where pressure in a viscous material would be greatest.
They are remnants of material extruding through holes in the formwork.
@here_garbage@EthicalSkeptic I don't think the stone was heated to soften it but it might have gotten hot as a result of whatever technique was used to soften the stone – there is some evidence for heat damage and discoloration.
However, while heat can melt igneous stone, limestone can not be melted.
@here_garbage@EthicalSkeptic The explanation is that it was actually easier to use non uniform material because the process they used naturally produced form fitting structures.
@EthicalSkeptic Perhaps the reason for this type of construction wasn't because it was hard, but rather because it was easy.
Close examination of the construction style does not suggest tedious and precise labor, but rather a process through which the precision emerges almost effortlessly.
@PoustMichael@TheProjectUnity There is good reason to assume the material was at some point viscous. But not poured like concrete, rather temporarily softened in place and compressed/deformed under load. Within this model, formwork was used to restrain and control the deformation process.
@TheProjectUnity Also note that the big scary values are a forecast for the maximum temperature in the largest cities, not the average temperature of the country, but the peak hypothetical temperature in places that maximally experience the Urban Heat Island effect – overlayed on a map of Europe.
@BrightInsight6 They will never admit that the Great Pyramid wasn't built by the Dynastic Egyptians – it would upend their position of authority over history, which to them is more important than the truth.
@TwistDead1 Makes sense. But what about the front section of the Sun Temple – the fit is too precise to be the work of the Inca, don't you think?
The foundation appears to be primitive stonework which is odd...
@Dr_Biberknetese@SunWeatherMan I don't know, I am observing this topic from the sidelines.
The last time the magnetic field collapsed over a period of 10,000 years from top to bottom.
The last top was 3,000 years ago, which suggests the next bottom is far out, however the decline seems to be accelerating...
@Dr_Biberknetese@SunWeatherMan I don't see evidence for a disaster cycle every 12k years. As I said I think the Younger Dryas event was anomalous, likely caused by meteor impacts and air bursts.
It's also important to note that the "rapid" sea level rise began prior to the YD (1A), and another after YD (1B)
@Dr_Biberknetese@SunWeatherMan Milancovic cycles among others.
The Younger Dryas was an anomalous and catastrophic event, the last transition into the interglacial was uniquely chaotic and destructive – resulting in the extinction of half the mega mammals and perhaps existing human civilizations.
@Dr_Biberknetese@SunWeatherMan No it's actually the other way, warming started roughly 15,000 years ago, so much so that climate was quite mild 13-15ka. The Younger Dryas interrupted the warming and plunged the world back into a cold period which lasted roughly a thousand years. Warming resumed afterwards.
@MichaelButtonX Societies could have flourished in equatorial regions for thousands of years during the glacial period.
Unlikely that agriculture was viable but livestock could have sustained a larger civilization.
Imagine domesticated mammoths 🦣 🔥
@Megalithic12000 Obligatory context that the "warnings" were inscribed during a climactic period known as the Little Ice Age (1300-1850), not the previous Medieval Warm Period. Further, the water levels have been this low repeatedly over the last centuries.
