Black Hole Photo Made

 -  -  9

Many years ago, Albert Einstein published his theory of relativity. It predicted that a sufficiently compact mass can deform matter to form a black hole. The boundary of no escape is called the event horizon. We were not able to prove this theory for many years because we could never produce an image of a black hole because black holes are technically invisible. That is until now.

Black holes are extremely far away and compact, so taking a photo of one is no easy task. In addition, black holes by definition are supposed to be invisible, although they can give off a shadow when they interact with the material around them. However, Kate Bouman, a graduate from MIT, was able to create an imperative algorithm that was able to stitch many photos of the black together to create a photo like this.

“We developed ways to generate synthetic data and used different algorithms and tested blindly to see if we can recover an image,” she told CNN.

“We didn’t want to just develop one algorithm. We wanted to develop many different algorithms that all have different assumptions built into them. If all of them recover the same general structure, then that builds your confidence.”

Thanks to her algorithm they were able to take a photo of the event horizon.  They could never take a photo like this before without it. Pretty soon, we’ll be able to travel in and out of the black hole.
