La teranyina c\u00f2smica<\/h2>\n\n\n\n

Alguna vegada t’has preguntat com s\u00f3n les nostres rodalies a l’univers?<\/p>\n\n\n\n

La teranyina c\u00f2smica \u00e9s una xarxa enorme i complexa de filaments de mat\u00e8ria fosca, gas i gal\u00e0xies, amb c\u00famuls i superc\u00famuls de gal\u00e0xies a l\u2019interior dels punts on hi conflueixen varios d\u2019estos filaments. L\u2019estructura de filaments deixa tamb\u00e9 grans espais buits, que s\u00f3n anomenats precisament \u201cbuits\u201d.<\/p>\n\n\n\n

<\/div>\n\n\n\n

El model<\/h1>\n\n\n\n

En este model 3D vegem una part de la teranynia que inclou a Laniakea, el nostre entorn c\u00f2smic m\u00e9s proper. Al centre del model es trobaria la nostra gal\u00e0xia, la Via L\u00e0ctia, per\u00f2 l\u2019escala no ens permet representar-la.<\/p>\n\n\n\n

S\u00ed que \u00e9s posible identificar diversos superc\u00famuls de gal\u00e0xies, objectes astron\u00f2mics que engloben milers de gal\u00e0xies, i que hem representat amb formes s\u00f2lides irregulars i suaus que semblen grans faves o fesols. Els filaments que posen en contacte dos superc\u00famuls tamb\u00e9 tenen nom, format pels dels mateixos c\u00famuls.<\/p>\n\n\n\n

S\u2019estima que Laniakea compren 100 000 gal\u00e0xies (la Via L\u00e0ctia inclosa).  La porci\u00f3 d\u2019univers representada al model cont\u00e9 de l\u2019ordre d\u20191 mil.li\u00f3 de gal\u00e0xies. El tamany de la part d\u2019Univers representada \u00e9s de m\u00e9s de 1000 mil.lions d\u2019anys-llum.<\/p>\n\n\n\n

Hem fet dues versions del mateix model: una llisa (Laniakea.stl) i un altra on els objectes estan identificats per la seua inicial en Braille (Laniakea Braille.stl). La llegenda en Braille est\u00e0 en el fitxer \u00abBraille legend.stl\u00bb.<\/p>\n\n\n\n
