In my previous blog I had a post about Gravitational Lensing but I never get tired of writing about them!
Anytime I start doubting General Relativity I google for images of Gravitational Lenses to believe in the field equations!. They're just too cool!!! :D
It is crazy! Here you are looking at one of the largest gravitationally bound structures in the whole visible universe -a galaxy cluster. That damn ring of multiple images you see is a result of curvature of space-time around the giant mass of the cluster and could be calculated with an astonishing accuracy using General Relativity.
And when you think deeply about General Relativity you see it is the MOST NATURAL thing that could exist!!! This blows up my mind!
