New Theory on Great Pyramid Construction

Scientists have a new idea about how the Great Pyramid in Egypt was built.

They think the builders used a pulley and counterweight system to lift the heavy stones.

The pyramid has 2.3 million limestone bricks, some weighing over 60 tons.

The researchers believe the pyramid was built from the inside out, starting at the core and moving upwards.

They found clues inside the pyramid, like the Grand Gallery, which they think was used for the pulley system.

This new theory is different from the old idea of using ramps to build the pyramid layer by layer.

The researchers think this method would have been faster and more precise.
