The expansion of the universe happens with acceleration and the tightening of matter into a black hole the same happens with acceleration. Coincidence? "I don't think so."
One of the purposes of the black hole is recycling of all the matter forms and turning them into their original forms: oxygen, deuterium, lithium and helium.
The Universe creation process isn’t a blast from a point, but the black hole-like puncture out of neighboring Universe through which energy from the neighboring Universe starts to outpour into ours, filling its emptiness. Basically, it’s like a start of a new child process, linked with the parental one.
The black hole is the very point, analogous of the one out of which our Universe emerged. It’s a super-conductive energetic channel, puncture into the space of Nothing, where energy of our Universe outpours, creating a new Universe there.
Black holes are energy channels with ultra-high pressure and low temperature, having superconductivity and designed to transmit energy, including in such States as matter and space.
It is believed that the peculiarity of black holes is their opacity for time and light. Time and light cannot penetrate black holes.
We can assume that white holes (stars) and black holes are two mutually degenerating, related entities, on the one hand, it is a black hole, on the other - white.
There is a star - it's a white hole and there is the opposite of it - it's a black hole. Through white holes energy comes to our universe, through black it is utilized, keeping the balance of energy. White holes are responsible for the expansion of the universe, black holes are responsible for compression. The older the universe, the less white holes it is, and the more black holes it is. Perhaps, there are two universes. They are like hourglass smoothly folded to a point, then spread out. From one energy flows into another and back again.
