Light from the background galaxy circles a black hole an increasing number of times, the closer it passes the hole, and we therefore see the same galaxy in several directions (credit: Peter Laursen). Looking near the black hole, we see more and more versions of the same galaxy, the closer to the edge of the hole we are looking. The mechanism is shown on the figure below: A distant galaxy shines in all directions - some of its light comes close to the black hole and is lightly deflected some light comes even closer and circumvolves the hole a single time before escaping down to us, and so on. Hence, when we observe a distant background galaxy (or some other celestial body), we may be lucky to see the same image of the galaxy multiple times, albeit more and more distorted. In the vicinity of a black hole, space curves so much that light rays are deflected, and very nearby light can be deflected so much that it travels several times around the black hole. You may also have heard that space itself and even time behave oddly near black holes space is warped. You have probably heard of black holes - the marvelous lumps of gravity from which not even light can escape. Our understanding of this mechanism has now been increased by Danish master's student at NBI, Albert Sneppen (credit: interstellar.wiki/CC BY-NC License). Because space curves around the black hole, it is possible to look round its far side and see the part of the gas disk that would otherwise be hidden by the hole.

The result, which even is more useful in realistic black holes, has just been published in the journal Scientific Reports.Ī disk of glowing gas swirls into the black hole "Gargantua" from the movie Interstellar. While this has been known for decades, only now do we have an exact, mathematical expression, thanks to Albert Sneppen, student at the Niels Bohr Institute. This phenomenon may enable us to see multiple versions of the same thing.
In the vicinity of black holes, space is so warped that even light rays may curve around them several times.
