The Bad Astronomer writes: "Astronomers have unveiled what may be the deepest image of the Universe ever created: the Hubble Extreme Deep Field, a 2 million second exposure that reveals galaxies over 13 billion light years away. The faintest galaxies in the images are at magnitude 31, or one-ten-billionth as bright as the faintest object your naked eye can detect. Some are seen as they were when they were only 500 million years old."
I have yet to see any problem, however complicated, which, when
you looked at it in the right way, did not become still more complicated.
