Problem of black banner has long engaged scholars of mathematics and physics all over the world. But only in the last few months, this information was disseminated among ordinary internet users, it is almost zahlestnuv whole. I am often asked what a “black banner, is not it someone’s joke or scientific innuendo – I think not. From a scientific point of view, the existence of ‘black banner’ was caused by the development of quantum physics and mathematicians have proved the theory of the existence of particles, dubbed “anahrony” – which can to mix back in time. In other words, a banner composed of these particles (perhaps, in part, or even completely), moves back in time! Black it is called, most likely because of the mystical rather than rational considerations (in this convergent views of most scientists), but more on that later. But beyond that begins the disagreement even the most eminent of them. Who created it? Where he came from and where it goes? The stories of those who clicked on it. All of this in our next article..
