I don't have the best Egyptian knowledge but I know they used a lot of hard stones granite and basalt because they are always questioning how they cut some of the stones particularly in the ancient kingdoms as they only had copper tools which are far softer. I know some of the old sarcophagus material are made with basalt and the one in the kings chamber is pink granite.

Why could that be important? These are volcanic rocks I wrote a note about paramagnetic rocks and biophotons a lot of these ancient sites involve volcanic rock which are paramagnetic. Stonehenge has diabase (the blue stones), Easter Island have the moai made from basalt and we have Egyptian things made from basalt and granite. Phil Callahan noticed the grass grew better around the statues on Easter Island (they had a higher brix) and suggested knowing the rocks are paramagnetic he proposed they are also emitting biophotons. So if you have ever been to a place like that you might have a reason why these places can make you feel different. If you stack in R.Carlson idea that Silbury hill near Avebury acts like a giant orgone accumulator stacking layers of non organic and organic material you might also have another idea too.

Yes plasma does related to electricity and magnetism, its hard to escape the physics of the universe. Dr Temple talk more about dusty complex plasmas its a big topic and he does a better job than a could in a paragraph.

If you go to a Native American ancient site where you are look out for the rock types see if you can spot a similar pattern, would be interested to know. I am hoping to get a paramagnetic meter for soil work so hopefully I can test some of the soil and plants around these sites in the U.K when I have more time to escape the fiat mine.
