If we think about our children and grandchildren, about their children and grandchildren, the danger of a collision, for example, of a comet with our planet grows with a geometric progression. Although the collision may occur and in a few hours after you read these lines. Just do not tell me about nuclear explosions, as an effective tool. There must be an opportunity to correct the error, then the solution can acquire reliability. The parameters include not only the time of detection and reaction but also the absence of unpredictable consequences from actions. The explosion is an uncontrolled process. The only way to solve the problem is a technical solution for managing gravity. This fundamental problem is no solved if we do not "bypass" Newton's third law and use solar energy for transportation. This means that evolution has programmed its death for the near future - and no this unlikely for many civilizations (which use the same laws of physics). Then there must necessarily be such an opportunity and hence, we can only to use chance it, no more. We need radical scientific theories, which do not deny but include the previous achievements of fundamental science. In this connection, the fundamental theory - the Holographic Principle provides a solution to this problem without denying the fundamental laws, explaining (not postulating) the long-range mechanism of gravity and the ability to control it without using exotic masses and energies. The Holographic Principle will soon be 30 years old and where are the practical results? We very-very at risk. The statistical period of mass extinctions due to the fall of large meteorites and comets has already been overcome. The greatest danger is represented by massive long-period comets, although they fall into the zone of planets of the terrestrial group about ten times less frequently than short-period comets. Their appearance is most often unexpected because of the arbitrary orientation of the planes of orbits and large or very large periods of circulation. Moreover, many of these comets are aperiodic, that is, they move along non-closed trajectories (parabolic or hyperbolic) and are therefore really new. These comets have a higher rate of collision with the Earth - up to 72 km / s (on opposite trajectories) (Wiki), which can lead to global catastrophic consequences - up to the destruction of the entire human civilization.
