Just about accordingly, before paragraph the doubtful universe signal that time FAST received to be located in 1300 light-year to control, this universe signal and common pulsar are distinguished somewhat, but unusual appearance resembles, the distance of 1300 light-year leaves us not far actually, the diameter of the galaxy has 100 thousand light-year. So famous scientist Hocking also is to express, to the universe medium signal does not reply easily, probable it is the signal that the position for him conceal pretends the civilization outside the ground to be given out into pulsar thereby.
