What Happens When You Entangle Black Holes
Black holes have been a part constant of science fiction for as long as I can remember, with storytellers using them as means to travel across the Universe and even to other universes. Of course, these concepts just exist within the realm of fiction. The reality of black holes though may be a bit weirder than expected, according to researchers at the University of Washington.
Quantum entanglement is an interesting phenomenon which links the quantum states of two particles. This means that the properties of one will dictate those of the other, when they are observed, no matter how physically separated the two particles are. What the researchers have done is considered what would happen if two black holes were entangled, and their conclusion is that a wormhole would form. The catch is that you would not be able to transport any information through the wormhole, because black holes do not allow light to escape. However, if you and a friend were to jump into the two black holes, what you would see and experience inside would be identical.
Perhaps this research will dash the hopes of some readers and writers, but it will likely increase our understanding of entangled quantum systems. Forming this theory required showing a relationship between quantum mechanics and classical geometry, which will be a useful tool for other researchers.
