[…] The "pupil" of the eye is actually a galaxy about 2.2 billion light years from Earth. That’s a fair bit! But it happens to sit almost directly between us and a much more more distant galaxy — one that is 11 billion light years away. As the light from the background galaxy passes by the nearer one, the gravity of the nearer one bends the path of that light, twisting it in what’s called a gravitational lens. […]

I think I have just read the best description of gravitational lensing I have seen. Thank you, Phil.

Now there’s an optimist for you! We finally find ONE and he says “if we can find as few as 50″! :0
