CBS News – Beneath the honking horns and operatic yelling of Naples, the most blissfully chaotic city in Italy, archeologist Raffaella Bosso descends into the deafening silence of an underground maze, zigzagging back in time roughly 2,300 years. 

Before the Ancient Romans, it was the Ancient Greeks who colonized Naples, leaving behind traces of life, and death, inside ancient burial chambers, she says. She points a flashlight at a stone-relief tombstone that depicts the legs and feet of those buried inside. “There are two people, a man and a woman” in this one tomb, she explains. “Normally you can find eight or even more.” This tomb was discovered in 1981, the old-fashioned way, by digging. Now, archeologists are joining forces with physicists, trading their pickaxes for subatomic particle detectors about the size of a household microwave.
