Wormholes are a hallmark of science-fiction that allow stranded heroes to jump into a black hole and be spit out the other side of the universe without a scratch. While scientific theories from the likes of Einstein do support the possibility of wormholes, in reality they would likely be extremely deadly. That is, if they even exist at all.

Scientists have spent decades pondering over the existence of such wormholes and now a team of scientists from MIT, Caltech, Harvard, and Google, have reported successfully creating a “holographic” wormhole using Google’s Sycamore quantum computer that allows information to travel through it. These findings were published Wednesday in the journal Nature.
