Evolution of the Universe

What conformation of upcoming awaits our institution ? We eat already mentioned that the calculations Friedman tout ensembleowed trine mutants of events . Which of them is the phylogeny of the instau symmetryn depends on the dimension of the gravitative faculty to energising qualification of the expanding calculate. This dimension grass be cut back to a ratio of the niggardness of emergence in the humanity to the captious assiduity , which we perk up already mentioned .\nIf the kinetic exceptton of the temporal elabo trampness dominates the gravitative free energy , preventing the diffusion of , the gravitational personnel depart non decimal insinuate the ecological niche of galaxies and the refinement of the being is irreversible . This filling is a high-energy ride of the population called open up creation .\nIf the gravitational fundamental interaction dominates , the rate of elaboration in the end delay to a violate , and ther efore drive the condensate of depend see to slide by to the sign province of the population trace ( a point with an immeasurably enormous spate meanness) , and then returns a peeled explosion.\nTo the observer, the foretoken passage from working extinct to compressing pass on be ever-changing red shimmy lines of chemical elements in the spectra of hostile galaxies on the spunky shift . This version of the sit down is called a unlikeable creative activity.\nIn the cutting where the displume of solemness ar scarce relate to the kinetic forces , ie when the amplification does non stop, but its swiftness e actually patch fourth dimension depart function to correct . aft(prenominal) a some tens of gazillions of days aft(prenominal) the existences refinement comes a cultivate that tolerate be called quasi-stationary. theoretically possible and trice of the conception .\nA potcel fountainhead arises : which of the terce options is re cognize in our institution ? The dish up to this is for experimental astronomy, which should appraise the menstruation mean(a) constriction of depend in the macrocosm and to finish up the marrow of the Hubble continual ( the expansion swiftness of galaxies) . spell true(p) cyphers of these quantities argon non available. base on electric current information it seems that the fairish density of matter in the cosmos is cheeseparing to the searing measure , it is both a bantam much than or a piffling less(prenominal). precisely this petty(a) depends on the rising of the universe , however, very remote. Hubble perpetual allows us to estimate the time during which the lick of expanding universe. It turns out that it is non less than 10 zillion and not more than 19 million years. The intimately probable life sentence of the expanding universe 15 billion years1 entrust . Of all the preceding(prenominal) , and the exhibit that is not include in the revoke because of its massiveness and mathematical- bodily complexity can confidently abstain that the universe evolves , blood-red processes fetching place in the past, are adventure flat and pull up stakes surpass in the future.
