Scientists at the University of St Andrews have used lasers to simulate a in their laboratory.
Professor Ulf Leonhardt and Dr Friedrich König used intense light pulses to create an artificial 'event horizon' - the defining feature of a black hole known as 'the point of no return'. The development may allow researchers to test Professor Stephen Hawking's theory that black holes are not black at all but in fact radiate light.
It is the first time that scientists have successfully simulated an event horizon using light. The St Andrews demonstration of the physics behind the event horizon, in which they measured the shifting of light, has been described as a 'milestone'.
