By Zeeya Merali STEPHEN HAWKING should be pleased. The first signs of an effect the British physicist predicted more than 30 years ago – known as Hawking radiation – have finally materialised from the simulated edge of a black hole. Quantum mechanics tells us that entangled pairs made up of a particle and its antiparticle can spontaneously pop out of otherwise empty space, exist for a fleeting moment, and then annihilate each other and disappear. In the 1970s, Hawking predicted that if such a pair were created near a black hole’s event horizon,
