Una pregunta que los cient\u00edficos no esperaban<\/span><\/strong><\/h4>\n

Durante siglos, los cient\u00edficos asumieron que el universo simplemente <\/span>es como es<\/span><\/em> .<\/span><\/p>\n

Pero la f\u00edsica moderna descubri\u00f3 algo sorprendente:<\/span><\/p>\n

El universo parece estar extraordinariamente bien ajustado para la vida.<\/span><\/strong><\/p><\/blockquote>\n

Esto no se hab\u00eda previsto.<\/span><\/p>\n

Fue descubierto.<\/span><\/p>\n

\nEl universo parece estar finamente equilibrado para la vida.<\/span><\/figcaption>\n<\/figure>\n<\/div>\n
\n

\u00bfQu\u00e9 significa \u201cajustado con precisi\u00f3n\u201d?<\/span><\/strong><\/h4>\n

El ajuste fino significa que muchas constantes fundamentales de la naturaleza:<\/span><\/p>\n

    \n
  • Debe estar dentro de un rango extremadamente estrecho.<\/span><\/li>\n
  • De lo contrario, la vida ser\u00eda imposible.<\/span><\/li>\n<\/ul>\n

    C\u00e1mbialos aunque sea ligeramente y:<\/span><\/p>\n

      \n
    • Sin estrellas<\/span><\/li>\n
    • Sin qu\u00edmica<\/span><\/li>\n
    • No hay planetas<\/span><\/li>\n
    • No hay vida<\/span><\/li>\n<\/ul>\n
      \n

      Ejemplos de ajuste fino (explicados de forma sencilla)<\/span><\/strong><\/h4>\n

      Aqu\u00ed hay algunos ejemplos:<\/span><\/p>\n

        \n
      • Gravedad<\/span><\/strong> ligeramente m\u00e1s fuerte \u2192 las estrellas se queman demasiado r\u00e1pido. Ligeramente m\u00e1s d\u00e9bil \u2192 las estrellas nunca se forman.<\/span><\/li>\n
      • Fuerza electromagn\u00e9tica<\/span><\/strong> Alterarla ligeramente \u2192 los \u00e1tomos no pueden existir<\/span><\/li>\n
      • Tasa de expansi\u00f3n del universo<\/span><\/strong> Demasiado r\u00e1pida \u2192 la materia nunca se agrupa Demasiado lenta \u2192 el universo colapsa<\/span><\/li>\n<\/ul>\n

        No se trata de m\u00e1rgenes peque\u00f1os.<\/span><\/p>\n

        Son <\/span>asombrosamente precisos<\/span><\/strong> .<\/span><\/p>\n

        \n
        \"\"

        <\/p>\n

        \nPeque\u00f1os cambios en las constantes f\u00edsicas impedir\u00edan la vida.<\/span><\/figcaption>\n<\/figure>\n<\/div>\n
        \n

        \u00bfDe qu\u00e9 grado de precisi\u00f3n estamos hablando?<\/span><\/span><\/strong><\/h4>\n

        Los f\u00edsicos describen algunas constantes como ajustadas a:<\/span><\/p>\n

          \n
        • 1 parte en 10\u2076\u2070<\/span><\/li>\n
        • 1 parte en 10\u00b9\u00b2\u2070<\/span><\/li>\n<\/ul>\n

          Estas cifras escapan a la comprensi\u00f3n cotidiana.<\/span><\/p>\n

          Esto no es normal en la naturaleza.<\/span><\/p>\n

          \n

          Por qu\u00e9 esto supone un problema para el azar<\/span><\/span><\/strong><\/h4>\n

          Las explicaciones basadas en el azar presentan dificultades porque:<\/span><\/p>\n

            \n
          • No se conoce ning\u00fan mecanismo que <\/span>establezca<\/span><\/em> estos valores.<\/span><\/li>\n
          • Los procesos aleatorios favorecen abrumadoramente a los universos sin vida.<\/span><\/span><\/li>\n<\/ul>\n

            Los universos que permiten la vida parecen ser extremadamente raros.<\/span><\/p>\n

            \n

            Explicaciones comunes ofrecidas<\/span><\/strong><\/h4>\n

            Los cient\u00edficos suelen proponer tres explicaciones:<\/span><\/p>\n

              \n
            1. Necesidad f\u00edsica<\/span><\/strong> \u2192 Las constantes <\/span>ten\u00edan<\/span><\/em> que ser as\u00ed (No hay evidencia que lo respalde).<\/span><\/li>\n
            2. Azar<\/span><\/strong> \u2192 Tuvimos suerte (Las probabilidades son incre\u00edblemente bajas).<\/span><\/li>\n
            3. Dise\u00f1o<\/span><\/strong> \u2192 El universo fue estructurado intencionalmente<\/span><\/li>\n<\/ol>\n

              Los datos en s\u00ed mismos no eligen.<\/span><\/p>\n

              pero <\/span>plantea la pregunta<\/span><\/strong> .<\/span><\/p>\n

              \n

              Por qu\u00e9 esto importa m\u00e1s all\u00e1 de la ciencia<\/span><\/strong><\/h4>\n

              El perfeccionamiento de los detalles no prueba la Biblia por s\u00ed solo.<\/span><\/p>\n

              Pero sugiere firmemente lo siguiente:<\/span><\/p>\n

                \n
              • El universo no es aleatorio.<\/span><\/li>\n
              • La vida no fue un accidente.<\/span><\/li>\n
              • La realidad parece tener un prop\u00f3sito.<\/span><\/li>\n<\/ul>\n

                Esto coincide notablemente bien con la afirmaci\u00f3n inicial de la Biblia:<\/span><\/p>\n

                \u201cEn el principio, Dios cre\u00f3\u2026\u201d<\/span><\/em><\/p><\/blockquote>\n

                \n

                Por qu\u00e9 esto plantea preguntas m\u00e1s importantes<\/span><\/strong><\/h4>\n

                Los ajustes finales no ponen fin a la discusi\u00f3n.<\/span><\/p>\n

                Comienza uno.<\/span><\/p>\n

                Si el universo est\u00e1 dise\u00f1ado:<\/span><\/p>\n

                  \n
                • \u00bfQui\u00e9n lo dise\u00f1\u00f3?<\/span><\/li>\n
                • \u00bfPor qu\u00e9 importa la vida?<\/span><\/li>\n
                • \u00bfPor qu\u00e9 estamos aqu\u00ed?<\/span><\/li>\n<\/ul>\n

                  La ciencia puede describir la sintonizaci\u00f3n.<\/span><\/p>\n

                  pero no el significado.<\/span><\/p>\n

                  \n

                  Un resumen sencillo<\/span><\/strong><\/h4>\n

                  El universo es:<\/span><\/p>\n

                    \n
                  • Regido por leyes precisas<\/span><\/li>\n
                  • Equilibrado al filo de una navaja<\/span><\/li>\n
                  • Extraordinariamente adecuado para la vida<\/span><\/li>\n<\/ul>\n

                    Eso exige una explicaci\u00f3n.<\/span><\/p>\n

                    \n

                    Reflexi\u00f3n final<\/span><\/strong><\/h4>\n

                    El ajuste fino no impone la creencia.<\/span><\/p>\n

                    Pero eso hace que <\/span>la indiferencia sea irrazonable<\/span><\/strong> .<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"featured_media":0,"template":"","categories":[142],"class_list":["post-56598","el-tallo","type-el-tallo","status-publish","hentry","category-cientifica"],"yoast_head":"\nAjuste fino del universo - CIG22<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/cig22.com\/he\/el-tallo\/ajuste-fino-del-universo\/\" \/>\n<meta property=\"og:locale\" content=\"he_IL\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Ajuste fino del universo\" \/>\n<meta property=\"og:description\" content=\"Una pregunta que los cient\u00edficos no esperaban Durante siglos, los cient\u00edficos asumieron que el universo simplemente es como es .
