One of the big detectors which record these collisions, they didn't think there was technology that could withstand the radiation that would be created in the LHC, so there was basically a lump of lead in the middle of this object with some detectors around the outside, but subsequently we have developed technology.
Unul dintre marii detectori  care înregistrează coliziunile, ei nu credeau că există tehnologie care ar putea rezista radiațiilor  create în LHC, și practic, în mijlocul acestui obiect  era o grămadă de plumb cu unii detectori pe exterior, dar ulterior am dezvoltat tehnologia.
