【明報專訊】A long-hidden narrow void in Egypt's Great Pyramid of Giza (胡夫金字塔) has been found by a group of scientists. The void, at least 30 metres in length, was found above the Grand Gallery (「大走廊」) — an ascending corridor that links the Queen's chamber to the King's in the heart of the pyramid. The researchers say the space has remained hidden since it was first constructed 4,500 years ago.
