Riddle in the Ruins (3x3)

Data de estreia: Nov 29, 2016

Black holes near pyramids in Egypt; weather radar in Texas finds a strange pulsing object; in 2015 satellite images show two large white objects with wakes that make them appear to be moving at very high speeds; ruins in Peru that suggest the Inca people knew more than previously thought; in 2001 images of a red swarm on an Indian river bank; a dark streak in the Andean desert of Bolivia may indicate the location of a meteor strike.
