A team of British researchers have successfully developed a black hole inside a fiber optic cable and to be more specific they created an artificial event horizon. Ulf Leonhardt, physicist at St. Andrews University, says that they actually created pairs of black and white holes which exist as long as they send light pulses through the fiber cable.

This experiment had the purpose of understanding the effects that take place near black holes and the reason why are not all gone is that they created an analogue of the event horizon and you would not be wrong to call it fake black hole. The not-so-real black holes are harmless and they lasted about 10 nanoseconds. Their plans for the future include the study of the similarities of the white holes and the black holes.
