Ma una sfida per gli astrofisici e i cosmologi moderni \u00e8 comprenderne il suo destino: in poche parole, come tutto avr\u00e0 fine. In base alle osservazioni, tra le teorie pi\u00f9 accreditate, ne sono state formulate tre: il Big Crunch, il Big Rip e il Big Freeze.<\/p>\n<\/div><\/div><\/div><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-2 fusion_builder_column_1_1 1_1 fusion-flex-column\" style=\"--awb-bg-size:cover;--awb-width-large:100%;--awb-margin-top-large:0px;--awb-spacing-right-large:1.92%;--awb-margin-bottom-large:0px;--awb-spacing-left-large:1.92%;--awb-width-medium:100%;--awb-order-medium:0;--awb-spacing-right-medium:1.92%;--awb-spacing-left-medium:1.92%;--awb-width-small:100%;--awb-order-small:0;--awb-spacing-right-small:1.92%;--awb-spacing-left-small:1.92%;\"><div class=\"fusion-column-wrapper fusion-column-has-shadow fusion-flex-justify-content-center fusion-content-layout-row\"><div class=\"fusion-text fusion-text-2\" style=\"--awb-content-alignment:justify;\"><h4 style=\"text-align: center;\"><strong>Big Crunch (Grande Collasso)<\/strong><\/h4>\n<\/div><div class=\"fusion-text fusion-text-3\" style=\"--awb-content-alignment:justify;\"><p>Questa ipotesi suppone che, dopo l\u2019attuale fase di espansione del nostro universo, la gravit\u00e0 torni ad essere la forza dominante, rallentando e perfino invertendo il processo. Risultato: l\u2019Universo tornerebbe a restringersi sempre di pi\u00f9. Le galassie inizierebbero ad avvicinarsi e a fondersi con maggiore frequenza, fino al condensarsi di tutta la materia esistente in un elemento sempre pi\u00f9 piccolo e denso.<\/p>\n<p>Si ipotizza che questo fosse lo stato iniziale del cosmo prima del Big Bang. Se il destino del nostro Universo fosse quello di tornare al suo stato iniziale, \u00e8 plausibile supporre che un altro Big Bang possa verificarsi e dare origine a un nuovo universo. Il nostro cosmo sarebbe uno di tanti universi che si susseguono in un ciclo infinito di espansioni e restringimenti della materia.<\/p>\n<\/div><div class=\"fusion-text fusion-text-4\" style=\"--awb-content-alignment:justify;\"><h4 style=\"text-align: center;\"><strong>Big Rip (Grande Strappo)<\/strong><\/h4>\n<\/div><div class=\"fusion-text fusion-text-5\" style=\"--awb-content-alignment:justify;\"><p>Questo scenario \u00e8 esattamente opposto alla precedente. Invece di rallentare e invertirsi, l\u2019espansione dell\u2019Universo accelererebbe sempre di pi\u00f9, portando le galassie ad allontanarsi per disfarsi sempre di pi\u00f9. Ogni struttura e corpo nel cosmo, perfino gli atomi, sarebbe dissolto a causa della violenta dilatazione del tessuto spazio-tempo. Una morte violenta per il creato, in cui nulla riuscirebbe a sopravvivere alla continua espansione del cosmo.<\/p>\n<\/div><div class=\"fusion-text fusion-text-6\" style=\"--awb-content-alignment:justify;\"><h4 style=\"text-align: center;\"><strong>Big Rip (Grande Strappo)<\/strong><\/h4>\n<\/div><div class=\"fusion-text fusion-text-7\" style=\"--awb-content-alignment:justify;\"><p>Secondo questo modello il nostro universo sarebbe destinato a spegnersi lentamente: ad ogni generazione di stelle, infatti, se ne formerebbero sempre di meno. Spenta anche l\u2019ultima stella, rimarrebbero solo buchi neri, stelle di neutroni e nane bianche, destinati a consumarsi ed evaporare. Alla fine l\u2019universo tender\u00e0 a raffreddarsi sempre di pi\u00f9 verso lo zero assoluto. Un cosmo luminoso e caldo si ridurrebbe a un luogo freddo, buio, quasi vuoto e con zero energia utilizzabile. Questa teoria sarebbe supportata dalle leggi della termodinamica e dal naturale aumento dell\u2019entropia (disordine) dell\u2019Universo.<\/p>\n<\/div><div class=\"fusion-separator fusion-has-icon fusion-full-width-sep\" style=\"align-self: center;margin-left: auto;margin-right: auto;width:100%;\"><div class=\"fusion-separator-border sep-single sep-dashed\" style=\"--awb-height:20px;--awb-amount:20px;border-color:var(--awb-color2);border-top-width:3px;\"><\/div><span class=\"icon-wrapper\" style=\"border-color:transparent;font-size:23px;width: 1.75em; height: 1.75em;border-width:3px;padding:3px;margin-top:-1.5px\"><i class=\"fa-angle-down fas\" style=\"font-size: inherit;color:var(--awb-color2);\" aria-hidden=\"true\"><\/i><\/span><div class=\"fusion-separator-border sep-single sep-dashed\" style=\"--awb-height:20px;--awb-amount:20px;border-color:var(--awb-color2);border-top-width:3px;\"><\/div><\/div><div class=\"fusion-text fusion-text-8\" style=\"--awb-content-alignment:justify;\"><p>Tra le tre, quella pi\u00f9 accreditata e attualmente supportata \u00e8 il Big Freeze. Sappiamo infatti che il nostro cosmo \u00e8 in una fase di espansione che accelera di continuo, sfavorendo quindi la teoria sul Big Crunch. Nonostante l\u2019accelerazione, anche l\u2019ipotesi del Big Rip \u00e8 considerata molto estrema stando alle osservazioni.<\/p>\n<p>L\u2019idea oggi pi\u00f9 condivisa \u00e8 quella di un\u2019espansione che allontaner\u00e0 tra loro le galassie le cui stelle si spegneranno a poco a poco. Il destino pi\u00f9 probabile del cosmo, almeno secondo le conoscenze attuali, sarebbe quindi un lento e inesorabile spegnimento, una stanza che rimarr\u00e0 buia per sempre.
