A s\u00faa lei da Gravitaci\u00f3n Universal dominaba a f\u00edsica do momento, pero entraba en conflito coa Teor\u00eda da Relatividade Xeral de Albert Einstein, que propo\u00f1\u00eda que a luz desviaba a s\u00faa traxectoria ata o dobre ante a presenza dun obxecto moi masivo debido \u00e1 curvatura do espazo. Ante a falta dunha evidencia experimental, o astr\u00f3nomo brit\u00e1nico Arthur Stanley Eddington liderou un experimento: utilizar a eclipse de 1919 para fotografar as estrelas que se atopaban ao redor do disco solar antes e durante o evento e as\u00ed comprobar se se produc\u00eda a deflexi\u00f3n ou desviaci\u00f3n da s\u00faa luz ao pasar preto do Sol.<\/p>\n<p>Grazas ao escurecimento do ceo durante a totalidade da eclipse, os dous equipos ingleses que formaron a expedici\u00f3n cient\u00edfica puideron comprobar meses despois ao revelar as placas fotogr\u00e1ficas que a posici\u00f3n dalgunhas desas estrelas alterouse. A s\u00faa luz, no canto de viaxar en li\u00f1a recta, desviouse lixeiramente ao pasar preto do campo gravitacional do Sol. Nesta conferencia, o investigador do IGFAE e profesor da USC Jos\u00e9 Edelstein relatar\u00e1 a historia de como Newton quedou eclipsado definitivamente por Einstein, quen se converteu na celebridade mundial que perdura xusto un s\u00e9culo despois.<\/p>\n<ul>\n<li>Lugar: Centro ABANCA Obra Social (praza de Cervantes) de Santiago de Compostela<\/li>\n<li>D\u00eda: 29 de maio de 2019<\/li>\n<li>Hora: 19:30 h<\/li>\n<li>Entrada gratu\u00edta ata completar aforo<\/li>\n<li>Idioma da charla: castel\u00e1n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Con motivo do centenario da eclipse total de Sol no que se comprobou por primeira vez unha das predici\u00f3ns da Teor\u00eda&#8230;<\/p>\n","protected":false},"author":21,"featured_media":3085,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0},"categories":[118,116],"tags":[],"aioseo_notices":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v18.4.1 -
