BBCnews does its best to summarize brain-crunching astrophysics with this report on new developments in cosmological theory. Turns out that recent observations of the cosmological background radiation (the leftover heat signature of the Big Bang) indicate the universe is much larger than it would appear by looking at. Involves the distance a light year travels getting longer as the universe expanded. If I'm reading it right, it provides a nice explanation for why the sky is dark, as well as why it wouldn't be possible (assuming you had a large enough telescope) to see the back of your own head from space.

Told you it was confusing.
