Sun’s 11-Year Cycle Caused by Dark Matter, Say Physicists

Posted by K R on

The way the planets influence the flow of dark matter into the Sun could explain one of the biggest mysteries in science, say particle physicists The Sun’s 11-year cycle is one of science’s greatest mysteries. Astronomers have watched in fascination for centuries as the number of sunspots increases and decreases over a regular cycle of almost exactly 11 years. More recently, they’ve discovered that at the same time, the Sun’s visible light luminosity changes by about 10^-3 while its x-ray luminosity changes by a factor of hundred. Nobody knows why this happens but various scientists have pointed to the remarkable correlation between the solar cycle and the orbital periods of the planets. In particular, Jupiter takes 11.8 years to orbit the Sun and there are a number of other tidal resonances of around 11 years associated with Saturn, Venus, Earth and Mercury.
