Were the pyramids carved out of mountains?

Were pyramids built from the outside?

Egyptians built the 480-foot-high Pyramid from the inside out, says French architect Jean-Pierre Houdin. Previous theories have suggested that builders on Egypt’s Giza Plateau hoisted the pyramid’s millions of multi-ton stone blocks using an external ramp.

How do we know how old the pyramids are?

One radioactive, or unstable, carbon isotope is C14, which decays over time and therefore provides scientists with a kind of clock for measuring the age of organic material. But material from the time of the pyramids lends itself well to radiocarbon dating because they fall into the 2575-1640 date range.

What is the mystery behind the pyramids?

The ancient Egyptians built nearly 100 pyramids over a millennium to serve as burial chambers for their royalty. They believed that the pyramids eased the monarchs’ passage into the afterlife, and the sites served as centers of religious activity.
