\nP\u00e5 m\u00e5ndagseftermiddagen lyckades forskare vid den stora partikelacceleratorn vid Cern med att skicka tv\u00e5 protoner mot varandra i en kollision.
\nI ett pressmeddelande ber\u00e4ttar CERN, the European Organization for Nuclear Research,<\/a>:<\/p>\n

Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring.<\/p><\/blockquote>\n

Acceleratorn gick ju s\u00f6nder nio dagar efter att den invigdes 2008. I fredags startades den igen, efter mer \u00e4n ett \u00e5rs reparationer. Denna f\u00f6rsta kollision mellan protoner var till f\u00f6r att testa att anl\u00e4ggningen fungerar. Projektet ska g\u00e5 in i sitt stora skede n\u00e4sta \u00e5r, n\u00e4r Big Bang, universums skapelse, ska efterapas.<\/p>\n

Det finns en del kritik och oro kring att Big Band ska \u00e5terskapas.<\/p>\n

Kritiker h\u00e4vdar att \u00e5terskapandet av Big Bang kan skapa ett svart h\u00e5l som kan hota hela jorden.<\/p>\n

V\u00e4rldens mest k\u00e4nda fysiker och experten p\u00e5 svarta h\u00e5l, Stephen Hawking, \u00e4r en av dem som har avf\u00e4rdat de p\u00e5st\u00e5dda riskerna, ber\u00e4ttar DN<\/a>:<\/p>\n

Kollisioner som utl\u00f6ser betydligt st\u00f6rre energim\u00e4ngder intr\u00e4ffar miljoner g\u00e5nger varje dag i jordens atmosf\u00e4r utan att n\u00e5got hemskt intr\u00e4ffar. V\u00e4rlden kommer inte att g\u00e5 under n\u00e4r LHC (acceleratorn vid Cern) s\u00e4tts p\u00e5 igen,” s\u00e4ger han i ett uttalande.<\/p><\/blockquote>\n

Sj\u00e4lv tycker jag det \u00e4r ett sp\u00e4nnande fysiskt experiment och jag har precis b\u00f6rjat f\u00f6lja experimentet p\u00e5 Twitter.<\/a><\/p>\n

Bloggen Tankar fr\u00e5n Roten tycker att DN rapporterade halvhj\u00e4rtat.<\/a>
