Black holes can be divided into “primitive” and normal.
The official science says that there are two types of black holes: traditional and “primitive”. In the first case they are formed after the death of a star, and the second from the remnants of dense matter, which remained after the Big Bang. Another difference is that traditional black holes have a circular shape, and the primitive oval.
Primitive black holes, scientists said, is that recently provoked gravitational waves at the distance of 1.4 billion light years.The exact same information about this can be read with a telescope Einstein, because he is 100 times more sensitive than other modern devices.
