The Nasa's Wilkinson Microwave Anisotropy Probe (WMAP), launched on 30 June 2001, has been since then taking the temperature of big bang afterglow, known as the "cosmic background radiation". If the standard big bang picture of the Universe is correct, the blotches and freckles should be scattered randomly about the sky. "The big surprise is they are not," says Chris Vale of the University of California at Berkeley. "The quadrupole and octupole blotches are aligned with each other - along what they call “the axis of evil."
According to some scientists like Joao Magueijo at Imperial College in London, who coined the term "the axis of evil", there may be something seriously wrong with our big bang models.
