Ha sigut assessora cient\u00edfica de l&#8217;Ag\u00e8ncia Espacial Europea entre altres col\u00b7laboracions.<\/p>\n<p>\u00d2mnium Cultural Terrassa i l&#8217;Associaci\u00f3 Astron\u00f2mica de Terrassa van convidar Al\u00edcia&nbsp;Sintes&nbsp;a parlar de les ones gravitacionals, un tema que ja va sortir a les darreres Jornades Relativistes de Terrassa (tamb\u00e9 coorganitzades per \u00d2mnium Cultural); aquest cop, per\u00f2, la jornada va coincidir amb la publicaci\u00f3 a San Diego, al mateix moment de la confer\u00e8ncia, de les dades d&#8217;un segon impacte de forats negres que s&#8217;ha pogut detectar amb el sistema&nbsp;LIGO. Els oients de Terrassa vam ser, doncs, espectadors privilegiats d&#8217;un fet que ser\u00e0 recordat a la hist\u00f2ria de la ci\u00e8ncia: la detecci\u00f3 i escolta d&#8217;ones gravitacionals.<\/p>\n<p>Per\u00f2, qu\u00e8 s\u00f3n les ones gravitacionals? La doctora&nbsp;Sintes&nbsp;va fer una xerrada d&#8217;una hora (<a href=\"https:\/\/www.youtube.com\/watch?v=IEHygva7EII&amp;feature=youtu.be\" target=\"_blank\">que podeu escoltar sencera al nostre canal de YouTube<\/a>) on va explicar en qu\u00e8 consisteix aquest fenomen, com va ser dedu\u00eft per Albert Einstein fa cent anys i com la tecnologia actual ha perm\u00e8s finalment construir un detector que al seu moment Einstein calculava que seria impossible de construir. Les ones gravitacionals s\u00f3n&nbsp;pertorbacions&nbsp;al mateix teixit de mat\u00e8ria&nbsp;creades&nbsp;per canvis de velocitat dels cossos, per\u00f2 s\u00f3n tan d\u00e8bils que l&#8217;ona creada per dos forats negres gegants (amb una suma combinada de 60 masses solars) ha creat una distorsi\u00f3 equivalent a allunyar el planeta Saturn un \u00e0tom d&#8217;hidrogen respecte al Sol. Imagineu quin grau de precisi\u00f3 t\u00e9 el sistema&nbsp;LIGO&nbsp;per arribar a detectar aquestes variacions!<\/p>\n<p>La confer\u00e8ncia de&nbsp;Sintes&nbsp;va ser molt pedag\u00f2gica i va anar acompanyada d&#8217;imatges interessants i il\u00b7lustratives dels assoliments cient\u00edfics en el camp de les ones gravitacionals. Al final de la xerrada el p\u00fablic assistent al Centre Cultural va poder preguntar i demanar m\u00e9s informaci\u00f3 sobre aquests grans aven\u00e7os en ci\u00e8ncia i tecnologia i la doctora&nbsp;Sintes&nbsp;va oferir unes respostes ben f\u00e0cils d&#8217;entendre.<\/p>\n<p>Si en voleu saber m\u00e9s, us recomanem que escolteu la confer\u00e8ncia aqu\u00ed:<\/p>\n<p><iframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/IEHygva7EII\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dimecres passat la doctora Al\u00edcia Sintes, de la Universitat de les Illes Balears, va impartir una confer\u00e8ncia al Centre Cultural de Terrassa amb el t\u00edtol &#8220;Les ones gravitacionals: les noves missatgeres de l&#8217;univers&#8221;<\/p>\n","protected":false},"author":93,"featured_media":12898,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[953,823,955],"post_headquarter":[1774],"post_project":[1844],"class_list":["post-12897","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized-ca","tag-alicia-sintes","tag-ciencia-en-catala","tag-ones-gravitacionals","post_headquarter-terrassa","post_project-ciencia-en-catala"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 -
