      Description

      I was curious to see if thanks to modern equipment and processing techniques you can actually capture these mind bending phenomena that happen in our universe, turns out you can For those who don't know gravitational lensing is a light distortion effect caused by large masses that bend space to the point it starts to behave like a lens, magnifying everything that lies behind. It's actually direct confirmation of Einstein's general relativity At the center of the cluster (that lies 2.3B LY away) you can see many distorted galaxies that dont actually belong to the cluster itself, but are much farther away - just magnified and distorted by space.
