Pyramids: How did the structure of the pyramids get the exact shape without modern technology?

Interesting science

The Egyptian pyramids astonish visitors not just because of their mummies’ secrets, but also because of their architecture and engineering. It is nothing short of a miracle that such structures were built in such a perfect manner without the use of contemporary technology in Egyptian society 4500 years ago. Despite the dearth of substantial evidence, a study has revealed how the Perfect Alignment of Pyramids may have been achieved.

If Kufu, the Great Pyramid of Giza, is selected, the west side of the pyramid’s base is somewhat longer than the east side. Each arm is 138.8 metres long on average. However, what’s remarkable is that they’re straighter and more accurate, and their alignment with the directions is great.

The cardinal points of the kufu pyramids, Egypt’s pyramid builders, are more precise than four minutes of an arc, or 15ths of a degree, according to archaeologist and engineer Glenn Dash’s study published in the Journal of Ancient Egyptian Architecture. However, the stars could align.

The alignment of the three major Egyptian pyramids, two of Giza and one of Dashur, is extremely precise, and such precision is impossible to achieve without the use of drones, blueprints, and computers in today’s world. All three pyramids, according to Dash, share the same flaw and are somewhat clockwise from the cardinal points.

There have been several suggestions as to how this may have been accomplished. It also incorporates the use of shadows cast by the Sun’s beams, which are aligned with the help of the pole star. It was once again impossible to determine how this alignment would have been attained.

Dash has come up with yet another easy explanation. According to their findings, the Egyptians may have employed equinox or Sampat, the two days of the year when day and night are of equal length, for perfect alignment as early as 4500 BC. The plane of the Earth’s equator crosses across the centre of the Sun’s disc just twice a year on this rare occurrence.

The prospect of using an alignment approach to measure isotherm or equinox was previously dismissed as having insufficient precision. Dash’s study has proved the efficacy of the isotherm approach. It makes use of a gnomon stick. Dash undertook his studies for this, using the shadow of September 22, 2016, to study the shadows dropping at regular intervals and accomplish accurate alignment using a curve composed of those places that could get the correct line from east to west. The approach is also known as the Indian circle method. However, there is no proof that the Egyptians adopted this strategy exclusively. However, it became evident from this that large bodies, such as pyramids, may be created using this basic process.
