The Shape of the Universe is...

...football (soccer for Americans), a volleyball , a doughnut or even a pringle. However, according to New Scientist on Thursday, the Universe could be shaped like a medieval horn.

Once again this is someone's pet theory for the shape of the Universe that has been invented to explain the data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP). One of the biggest puzzles to come from the data is the low l multipole or more simply, why there isn't as much large scale structure in the background radiation from the Big Bang as was expected. This also comes at a time when the football shaped Universe might be running into some problems as it predicts repeating structure which isn't seen.

It can't be long before we get a Universe shaped like a small plastic toy from a Christmas cracker.
