Ulm University scientists have found evidence suggesting that the Universe is small and finite, and shaped like a 3-torus (doughnut).

They used three techniques to compare predictions of how the cosmic microwave background’s temperature fluctuations in different areas of the sky should match up in both an infinite Universe and a doughnut one. In each case, the doughnut gave the best match to the Wilkinson Microwave Anisotropy Probe data.

The team has even been able to pinpoint the probable size of the Universe: 56 billion light years across.
