“No recordo com va ser que vaig decidir que la hist\u00f2ria de l’Univers podia constituir la base del text de la Cant\u00e0nia del 2018 quan la meravellosa gent de l’Auditori que s’encarrega d’organitzar-les em van fer la proposta.\u00a0<\/i>Fa disset anys havia escrit un musical amb el compositor \u00d2scar Roig sobre la fam\u00edlia, el temps i la mort, a partir de la interpretaci\u00f3 sui generis d’alguns conceptes de f\u00edsica qu\u00e0ntica (El temps de Planck, que es va veure l’any 2000 al Teatre Romea) i des d’aleshores el tema de l’Univers, de com es va originar a partir d’una gran explosi\u00f3 (“Big Bang”) fa tretze mil milions d’anys i de les lleis cient\u00edfiques que el regeixen, sempre m’havia atret. <\/i>
\n
\n<\/i> A l’Univers, tot es belluga. Tot s’escalfa o es refreda. Les part\u00edcules vibren. I qu\u00e8 \u00e9s la m\u00fasica? Exactament aix\u00f2: vibraci\u00f3, temperatura, part\u00edcules en moviment fren\u00e8tic o pausat, ca\u00f2tic o harm\u00f2nic. Per\u00f2 tamb\u00e9 \u00e9s \u00e0nima, sentiment, misteri. No podem at\u00e8nyer nom\u00e9s amb la ra\u00f3 la immensitat de l’Univers i la m\u00fasica ens pot ajudar a entendre’l. I \u00e9s el que ha fet en Llu\u00eds Vidal amb la seva composici\u00f3 lleugera i profunda alhora, “c\u00f2smica”, plena de color, de joc, de saviesa, de vida… Ha sabut tocar la m\u00fasica de l’Univers. Misteriosa i evocadora.”<\/i>
\n
\n<\/i><\/p>\n

Els cient\u00edfics afirmen que fa aproximadament tretze mil milions d’anys, una gran explosi\u00f3 va originar el nostre Univers. En els primers instants de la seva exist\u00e8ncia, es varen crear les quatre dimensions que ara anomenem “espaitemps”: tres d’espai i una de temps. Quatre forces tamb\u00e9 es van separar ja en el primer segon de vida: la for\u00e7a electromagn\u00e8tica, les dues forces nuclears -forta i d\u00e8bil- i la for\u00e7a gravitacional. Tamb\u00e9 des d’aquests primers instants, apareixen les part\u00edcules: protons, electrons, neutrons. En aquests inicis, tot t\u00e9 la forma d’una mena de sopa ca\u00f2tica i incandescent. Despr\u00e9s, l’Univers progressa i la temperatura, extremadament calenta, es va refredant de mica en mica.<\/p>\n

Aquest refredament provoca que les part\u00edcules comencin a agrupar-se entre elles.\u00a0I \u00e9s aix\u00ed com comen\u00e7aran a apar\u00e8ixer els \u00e0toms: combinacions de nuclis de neutrons i protons amb electrons donant-hi voltes.\u00a0I l’Univers es refredar\u00e0 encara m\u00e9s i els \u00e0toms es combinaran entre ells conformant mol\u00e8cules. I les mol\u00e8cules s’ajuntaran entre elles, etc\u00e8tera. Es crea, d’aquesta manera, el que anomenem “mat\u00e8ria”. L’Univers continuar\u00e0 avan\u00e7ant en la dimensi\u00f3 temporal i es refredar\u00e0 cada cop m\u00e9s, i apareixeran tota mena de combinacions de part\u00edcules que conformaran gal\u00e0xies, nebuloses, estrelles, planetes…<\/p>\n

En un d’ells, anomentat Terra, milers de milions d’anys m\u00e9s tard, aquestes combinacions de part\u00edcules i d’elements produiran aigua i altres components que faran sorgir la vida. I la vida crear\u00e0 \u00e9ssers amb capacitat d’observar i de recrear tota aquesta hist\u00f2ria: la m\u00fasica de l’Univers.<\/p>\n
