Scientists are close to solving the mystery of gravitational waves

In modern physics, gravity - one of the mysteries. We just learned to measure its manifestation in the form of gravity. But what is gravity, where it is taken as passed - to answer unequivocally modern science has not yet in force.
The fact that gravity is one of the the four fundamental interactions - transfer of energy forms - and at the same time the weakest of all. But the main problem lies elsewhere.
It is known that the three most-studied interactions are mediated by using particle. And if other types of interactions these particles are known, and their existence confirmed experimental (direct or indirect way, even with large assumptions), then for all gravity much more difficult.
At the moment, not possible to confirm the fact of the presence of not only the so-called gravitons (theoretical particle responsible in some of the concepts for the transfer of Physics gravity and the creation of gravitational fields), but these traces of gravity, which would determine the nature of its transmission (or, say, transportation space-time).
According to the same theory, which suggests the presence of gravitons, it turns out that gravity should be transmitted in the form directed quantized (i.e., consisting of particles or "like particles" - energy packets with a certain value) waves - gravity radiation. It should manifest itself in the form of huge waves from any large space objects and events - black holes and galaxy clusters, supernovae at birth. However, to find them have so far failed.
And January 11, 2016 Arizona State University cosmologist Lawrence Krauss (Lawrence Krauss) wrote in his Twitter"My suspicions about the opening LIGO It has been confirmed by independent sources. Stay in touch! Gravitational waves can be detected! "
Gravitational-wave Observatory, LIGO It is one of the most important places where the study is conducted gravity and search of gravitational waves. LIGO station using advanced laser interferometers for the detection of gravitational waves. Although still in September 2015 Krauss hinted that LIGO detector were found signs of the elusive gravitational waves, official confirmation of this has not appeared. Shortly before that, the complex has been upgraded, and there started the Advanced LIGO experiment, which may lead to the detection of gravitational waves.
Official statements from the observatories in the meantime has been received (they are expected to at least February) so experts believe that it is too early to rejoice and to spread rumors about the extremely important opening. The more that the previous findings of the experiment BICEP2It turned out to be wrong: the signal was actually not caused by gravitational waves, and dust.
Why do it, and why is it so important? Any theory - the beginning of practice. Without quantum physics would not exist GPS, satellite communications, modern transistors and quantum computers (and optical communication lines too). Working, complete theory describing gravity, might allow a more detailed study of the universe, its laws, move objects, black holes, dark energy and dark matter. And, it is possible to create entirely new types of movement in space (or time). Until then, we are not available or quantum jumps or "wormholes" or superluminal velocity.
