Twenty degrees Celsius. Sixty-eight degrees Fahrenheit.

That's the temperature inside the Great Pyramid of Giza. Always.

Outside: 45°C blazing desert heat during the day. 5°C cold desert nights.

Inside: 20°C. Constant. Comfortable. Perfect.

Tomorrow? 20°C.
Next week? 20°C.
Next month? 20°C.

For 4,500 years, every single day, the Great Pyramid has maintained this temperature.

No electricity. No air conditioning. No heating system. No moving parts. No maintenance.

Just stone, geometry, and physics.

How is this possible?

The answer involves five factors working together:

Massive thermal mass (6 million tons of limestone)
Pyramid geometry (minimal surface area for volume)
Internal shaft system (natural air circulation)
Strategic passages (convection currents)
Bedrock connection (stable earth temperature as heat sink)

The result: passive climate control that NASA is now studying for space habitats.

Modern buildings with air conditioning still show 5-10°C temperature variation. The pyramid: less than 1°C variation annually.

How this challenges our view of ancient technology

The Great Pyramid isn't just a tomb. It's a masterclass in passive thermal engineering.

4,500 years old. Still working perfectly. No electricity required.

Ancient Egyptians built something we're still trying to understand.
