Black hole in the Universe
Black holes are the corpses of giant stars. When such a star runs out of fuel, its core collapses inward. Gravity pulls everything into an increasingly fierce grip. Temperatures reach 100 billion degrees. Atoms are smashed. Electrons are shredded. Those pieces are further crumpled.
Q represents the strength of the bonds among galactic matter to form clusters (stars, galaxies, and clusters of galaxies). Q represents the ratio of two fundamental energies; the one part in 100,000 ratio between the rest mass energy of matter and the force of gravity. Q also represents the amount of energy as a proportion to their rest mass energy, needed to break up and disperse the clusters.
If Q were much larger or smaller than 10–5, then life as we know it would not exist. If this ratio is much bigger, Stars and galaxies would be more closely packed, and they would more likely collide with each other, thus decreasing the chance to retain stable planetary systems and therefore less likely for life as we know it to exist.
Stars would collapse swiftly into black holes and the surviving gas would blister the universe with gamma rays. The Universe would be inert and structure less and it would be a violent place, dominated by giant black holes. The universe would be rough with all black holes and very tightly grouped clusters of stars.
If Q a lot smaller, gas would never condense into galaxies If Q happens to be only a bit smaller, star formation would be slow, clustering would be less likely to occur, the universe would be smoother and it would take more time for the universe to evolve to the current structure. There would not be sufficient time for stars, galaxies, and planets to form, and then for life as we know it to develop and evolve.
