Analysis of Galaxy Spin Reveals Universe Might Be Left-Handed 171

Taco Cowboy writes "Someone from US is claiming that the universe was born spinning and continues to do so around a preferred axis." The full paper has more details. The researchers measured the spin of a number of galaxies in the northern hemisphere; the data indicated a distinct bias toward left-handed spins. "Longo says that the chance that it could be a cosmic accident is something like one in a million. 'If galaxies tend to spin in a certain direction, it means that the overall universe should have a rather large net angular momentum. Since angular momentum is conserved, it seems it [the universe] must have been "born" spinning.'" Naturally, there is some skepticism: "Neta Bahcall, an astrophysicist at Princeton University in the US, feels that there is no solid evidence for a rotating universe. 'The directional spin of spiral galaxies may be impacted by other local gravitational effects,' she said. She believes that this could result in small correlations in spin rotation over distances less than about 200 Mpc – whereas the observable universe is about 14 Gpc in size."
