原文开头
Quantum theory says a vacuum isn’t truly empty. Probing it with powerful lasers could finally expose its hidden structure, discovers Jon Cartwright ON THE outskirts of Hamburg, Germany, pulses from one of the world’s biggest X-ray lasers race underground towards a stainless-steel chamber. Directly above, another huge laser waits. Soon, its beam will be sent down to meet the X-rays head on, bringing the two extraordinarily powerful beams of light together in an almighty burst of energy. The modern concept of the vacuum can be traced to the work of theorist Paul Dirac in the late 1920s. …
