Chambers Generating Heat


So here is the thing- no solid proof has been found on when and how these mysterious structures were made. Then it found that the Great Pyramid has some hidden chambers from which heat/energy is emitted. What is happening?
A thermal scan performed on the Great Pyramid in 2015 revealed that there were three specific areas in it which were generating heat. Some ‘mysterious technology’ is ascribed the reason for this heat production. Some heat areas in the upper half of the Pyramid have led to the speculations that there are more chambers hidden inside.
