If we take a look on Figure we see depress tendencies.
What are the causes of this phenomena?
Why, particularly in our days, temps of its propagation have risen?
Before, we have been investigating long cycles of Kondratiev N. And have found that they coincides with change in the length of earthdays, rotational velocity of Earth during decades and centuries. And the velocity of flow, rotation of Earth significantly connected to the density of cosmos. For new physicists it is the density of the ether. The energy of ether vortex “feeds” all living species on Earth. Thus, we have come to the idea to see how energetic flows of the ether are connected with an intensity of terrorism acts. Let’s compare graphs describing velocity of rotation of Earth (the length of earthdays) with the intensity of the acts in recent years.
Let’s add some data on the intensity of the solar radiation in the electromagnetic range (see.: http://www.areyou.ru/sun/sun.html).

The connection of the number of victims with Wolf’s number representing the intensity of solar activity is different, in some degree contrary to the connection of rotational velocity (the length of earthdays) of Earth. The causes of this connection on the level of physical processes on the scale of solar system have been explained. (see: Dyatlov V.L. Polarizing model of heterogeneous physical vacuum. Novosibirsk, editing of the Mathematics Department, 1998, 183 pp.). This is the sphere of disputes of physicists and mathematicians. Dyatlov V.L. considers that the gravity-spin and electromagnetic cosmic energies transform into one another according to the law of continuity of complete electrical, magnetic, gravitational and spin current. But this is according to mathematicians, physicists, but we analyze a terrorism as a social and psycho-cosmic phenomenon. Therefore, we take from them only reasonable and sometimes shining scientific terms – gravity-spin and electromagnetic energies. For ourselves, we note that the connection between Earth's rotational velocity and the number of victims of terrorist attacks is deeper, more evident than the Wolf’s number.
In 2014 43542 people died from terrorists. This surge in fatalities from terrorist attacks is linked to the war in Syria. Only in Syria, there were killed more than 190 thousand of people. According to the Syrian Center of Monitoring Human Rights 33278 people of them were civilians. http://www.rbc.ru/politics/01/01/2015/54a564b59a7947111c67297f
