\nOamenii de \u015ftiin\u0163\u0103 urm\u0103resc de mult timp o \u00een\u0163elegere mai profund\u0103 a g\u0103urilor de vierme \u015fi acum par s\u0103 fac\u0103 progrese. Cercet\u0103torii au anun\u0163at c\u0103 au simulat dou\u0103 g\u0103uri negre minuscule – acele obiecte celeste extraordinar de dense, cu o gravita\u0163ie at\u00e2t de puternic\u0103 \u00eenc\u00e2t nici m\u0103car lumina nu poate sc\u0103pa – \u00eentr-un computer cuantic \u015fi au transmis un mesaj \u00eentre ele prin ceea ce echivaleaz\u0103 cu un tunel \u00een spa\u0163iu-timp.<\/p>\n
\nA fost o “gaur\u0103 de vierme bebelu\u015f”, potrivit Mariei Spiropulu, fizician la Caltech , co-autor al cercet\u0103rii publicate \u00een revista Nature. \u00cens\u0103 oamenii de \u015ftiin\u0163\u0103 sunt departe de a putea trimite oameni sau alte fiin\u0163e vii printr-un astfel de portal, a spus ea.<\/p>\n
\n“Din punct de vedere experimental, pentru mine, v\u0103 voi spune c\u0103 este foarte, foarte departe. Oamenii vin la mine \u015fi m\u0103 \u00eentreab\u0103: “Po\u0163i s\u0103-\u0163i bagi c\u00e2inele \u00een gaura de vierme?”. Deci, nu”, a declarat Spiropulu reporterilor \u00een timpul unei \u00eent\u00e2lniri video.<\/p>\n
\n“Exist\u0103 o diferen\u0163\u0103 \u00eentre ceva posibil \u00een principiu \u015fi posibil \u00een realitate”, a ad\u0103ugat fizicianul \u015fi coautorul studiului Joseph Lykken de la Fermilab, laboratorul american de fizic\u0103 a particulelor \u015fi acceleratoare. “A\u015fa c\u0103 nu v\u0103 \u0163ine\u0163i respira\u0163ia \u00een leg\u0103tur\u0103 cu trimiterea c\u00e2inelui prin gaura de vierme. Dar trebuie s\u0103 \u00eencepem de undeva. \u015ei cred c\u0103, pentru mine, este pur \u015fi simplu interesant c\u0103 am reu\u015fit s\u0103 facem asta.”<\/p>\n
\nCercet\u0103torii au observat dinamica g\u0103urilor de vierme pe un dispozitiv de la Google, apar\u0163in\u00e2nd companiei Alphabet, numit procesorul cuantic Sycamore.<\/p>\n
\nO gaur\u0103 de vierme – o ruptur\u0103 \u00een spa\u0163iu \u015fi timp – este considerat\u0103 o punte \u00eentre dou\u0103 regiuni \u00eendep\u0103rtate din univers. Oamenii de \u015ftiin\u0163\u0103 le numesc poduri Einstein-Rosen, dup\u0103 numele celor doi fizicieni care le-au descris – Albert Einstein \u015fi Nathan Rosen.<\/p>\n
\nAstfel de g\u0103uri de vierme sunt \u00een concordan\u0163\u0103 cu teoria relativit\u0103\u0163ii generale a lui Einstein, care se concentreaz\u0103 asupra gravita\u0163iei, una dintre for\u0163ele fundamentale din univers. Termenul “gaur\u0103 de vierme” a fost inventat de fizicianul John Wheeler \u00een anii 1950.<\/p>\n
\nSpiropulu a declarat c\u0103 cercet\u0103torii au g\u0103sit un sistem cuantic care prezint\u0103 propriet\u0103\u0163ile cheie ale unei g\u0103uri de vierme gravita\u0163ionale, dar care este suficient de mic pentru a fi implementat pe hardware-ul cuantic existent.<\/p>\n
\n“Arat\u0103 ca o ra\u0163\u0103, merge ca o ra\u0163\u0103, scoate sunete ca o ra\u0163\u0103. A\u015fa c\u0103 asta putem spune \u00een acest moment – c\u0103 avem ceva care, \u00een ceea ce prive\u015fte propriet\u0103\u0163ile pe care le analiz\u0103m, arat\u0103 ca o gaur\u0103 de vierme”, a spus Lykken.<\/p>\n
\nCercet\u0103torii au declarat c\u0103 \u00een cadrul experimentului nu a fost creat\u0103 nicio ruptur\u0103 de spa\u0163iu \u015fi timp \u00een spa\u0163iul fizic, de\u015fi o gaur\u0103 de vierme traversabil\u0103 pare s\u0103 fi ap\u0103rut pe baza informa\u0163iilor cuantice transmise cu ajutorul codurilor procesorului cuantic.<\/p>\n","protected":false},"excerpt":{"rendered":"
