It only looks like gold if you’re a fool. There should be a term for that.

Do we not actually know if pyrite conducts electricity or not? This seems like Nobel Prize territory right here.

This is some real dumb shit. While there is still a lot of archaeological work to be done at Teotihuacan. It was a city center.

The liquid mercury bit was a piece of folkloric art, using the various precious metals and jewels as a representation of a landscape under the stars. The mercury represented lakes on the landscape.

Dumb shit is far dumber than the cool shit they were doing artistically.

And racist too, they say the ancient inhabitants could not have had knowledge of the solar system, because………? I guess they didn’t have eyes to see the stars and planets at night and track them like every single other civilization on earth has done. Racist horseshit.

Is be a lot more impressed if they found solid mercury under the pyramid. It would be amazing that they managed to keep it that cold for so long.

They lived a long time ago, therefore they had to be stupid. I find this offensive. An ancient Greek philosopher calculated the circumfrence of the Earth with pretty decent accuracy given the tools available to him at the time. The ancient Egyptians were not dumbasses unable to make observations and record them over time.
