Universe could be football-shaped
This is not a joke. I have found this article on Nature magazine.
The idea that the universe could really have such a perfectly symmetrical structure comes from observations of NASA´s Wilkinson Microwave Anisotropy Probe (WMAP) satellite.
It was looking back to the universe when it was 380,000 years old, and it calculated radiation data that assumes this conclusion by analyzing the microwave background in the cosmos.
The explanation of the method used here is compared to a bathtub: neither do you have any waves in your bathtub, nor could the satellite see any waves appearing in the universe. Therefore the universe needs to be finite. The best explanation for the non-existence of waves is that the universe is formed like a Poincaré dodecahedral space. Why? Because 12 curved pentagons produce exactly these patterns.
But, after all, it would be a surprise if the universe was so small. And "it's going to be a surprise if the Universe has chosen such a beautiful platonic form", says cosmologist Janna Levin of the University of Cambridge, UK.
If the theory is true, then the most distanct objects looked at at the same time, would appear in opposite of each other. In 60 billion light years on a journey across the universe, you would come back to where you´ve started.
A method how you could also prove this theory would be recognizing repetitive patterns. They appear when background radiation has travelled far enough in space to meet itself again and creates circular patterns.
