The sun was silent

The sun is in an unusually silent period, with less black streaks and a sudden weaker magnetic field from 1913 to the present.

A silent sun means that global positioning systems work more accurately, satellites are on longer trajectories, even the effects of man-made global warming downward trend.

The reduced activity of the sun also causes the earth's atmosphere to shrink, but that's not a big deal. During the period of abnormal silence on the regular cycle of the sun's life, the sun does not attack the earth blasted by short radiation rays, which help the earth's atmosphere expand.

Researchers at the University of Texas (USA) found that the boundary of the upper atmosphere is at the lowest level in the history of space, about 200 km lower than normal.
