Yes, building the Pyramids today with the same materials would be practically impossible!! A copy of a comparable edifice could be created, but it would only survive 4-12,000 years. A copy could be built out of steel and concrete, but it would be hollow and considerably lighter! The ancient Egyptians made use of the same materials as we do today, so constructing the Pyramids was not even difficult at that time.
The foundations of the Pyramids are composed of fine crushed stone mixed with sand. The stones in the mixture are very heavy so they provide stability even under the weight of the immense structures above them. The ancient Egyptians used wood for their buildings and ships; they also often burned the trees down during the construction process to use the ashes as cement. But even though wood is flexible, it can still bear great weights. Ancient Egyptian boats were made of tree trunks and were quite sturdy.
As far as we know, the first Pyramid was built by Pharaoh Chephren around 2500 B.C. It was named after him and was located near Cairo. Later on, other pyramids were built by several other pharaohs. Most famous are the two Pyramids of Giza, which are still visible today. They are the largest works of human engineering ever built. The Egyptians used local granite for their pyramids but they also worked with limestone and sandstone.
In conclusion, yes, you can still build a pyramid today!
Because of our progression away from authoritarian rulers like the Pharaohs, the building of the Pyramids as they were is unachievable. Modern concrete and crushed building materials are not the same as a single piece of solid granite rock. The Egyptians had no way to transport rocks of that size so they built their pyramids out of mud brick with some sand mixed in for extra weightlessness.
Also because the Egyptians weren't very good at keeping track of time so they built their great monuments as reminders to themselves about what they had done and what remains to be done. They didn't want to forget something important!
And finally, the cost of constructing a pyramid would have been too high for any but the richest Egyptians. Only the pharaoh himself might have been able to afford such an act of vanity.
After that moment in pyramid history, no more pyramids were built, yet their legacy continues on in various ways. Pyramids and other ancient Egyptian structures, such as the monolith, have had an impact on modern architecture. Have you ever seen the Washington Monument, for example? It was based on an ancient Egyptian model.
Furthermore, parts of ancient Egyptian technology have been used by modern engineers: The arch is an ancient Egyptian invention that has been adopted into many different civil engineering techniques including bridges, tunnels, and dams. Also, the stirrup was a mechanical improvement on the footbridge used by horses to cross ditches or narrow streams. Finally, a screw thread was invented by Khufu (also known as Chephren) for use with his stones.
In conclusion, ancient Egypt was home to some of the most advanced civilizations in the world. Their inventions and technologies still influence modern society today.
A pyramid makes good use of material by becoming as tall as feasible. The second project demonstrates that triangular forms are more robust and do not collapse as easily as squares. When the Egyptian city of Cairo was devastated by an earthquake 700 years ago, the pyramids held fast. In the modern world, skyscrapers are often described as "pyramid-shaped," because they have several levels high. Although they are not made of stone, they share many characteristics with the ancient monuments.
Pyramids were not only used for tomb markers but also as religious temples. They were places where Pharaohs were buried or sacrificed animals. The biggest temple in Egypt is believed to be the Great Pyramid of Giza which is today one of the highest points on Earth. It is built around 2500 years ago and at its peak was the tallest building in the world. Today it is still one of the most important symbols of ancient Egypt.
In conclusion, pyramids were used for burial purposes, as tombs, or as temples. They were usually built by royal decree over many years using slave labor. A pyramid structure is extremely stable because each layer is supported by the one above it. No element of construction has any effect beyond what is seen from ground level. However, when excavating sites, parts of pyramids can be damaged or destroyed. Sometimes entire pyramids have been demolished although most of them remain intact today.
