TOKYO The riddle of what lies inside the pyramids has fascinated Egyptologists for centuries, yet the risk of damage and the complexity of excavating these ancient structures has meant we still only have a limited understanding of what is hidden at their core.

Now, intriguingly, elementary cosmic particles that hurtle through space may just provide scientists with a noninvasive way of peering inside these monolithic feats of engineering, in much the same way as X-rays are used to see inside the body.
