Black hole mysteries



Scientists are just getting to know the black holes that help anchor our cosmos

 
Hungry black hole
Though black holes are invisible, they can create brilliant light shows. This illustration shows a black hole devouring a star.

The first rule for anyone dealing with a black hole is, of course, don’t get too close. But say you do. Then you’re in for quite a trip — a one-way trip — because there is no coming back once you fall into a black hole.
A black hole isn’t actually a hole. If anything, it’s the opposite. A black hole is a place in space containing a lot of stuff packed very closely together. It has accumulated so much mass — and therefore gravity — that nothing can escape it, not even light. And if light cannot escape a black hole, then neither can you.

Luckily, you don’t have to fall into a black hole to learn about this cosmic phenomenon. Decades of study from a safe distance have taught scientists quite a lot. Those observations, including startling discoveries made in recent months, continue to add to our understanding of how black holes help shape the universe.

    Galactic clusters formed by conglomeration?
    No. Galactic clusters formed by Big-Bang's fragments dispersion, evidenced by their Newtonian behavior including their separation acceleration.

    The big bang is the shattering of the short-lived singularity mass into fragments that later became galactic clusters. This is inflation. The shattering is the start of movement of the shatters i.e. the start of reconversion of mass into energy, which is mass in motion. This reconversion proceeds at a constant rate since the big bang as the resolution of gravitons, their release from their shatters-clusters, proceeds at constant rate due to their weak specific force due to their small size.

    A commonsensible conjecture is that Universe Contraction is initiated following the Big-Bang event, as released moving gravitons (energy) start reconverting to mass (gravity) and eventually returning to black holes, steadily leading to the re-formation of The Universe Singularity, simultaneously with the inflation and expansion, i.e. that universal expansion and contraction are going on simultaneously.

    Conjectured implications are that the Universe is a product of A Single Universal Black Hole with an extremely brief singularity of ALL the gravitons of the universe, which is feasible and possible and mandated because gravitation is a very weak force due to the small size of the gravitons, the primal mass-energy particles of the universe.

    This implies also that when all the mass of the presently expanding universe is consumed by the present black holes, expansion will cease and be replaced with empansion back to THE Single Universal Black Hole.
