However, this explanation can be criticized on the fact that it assimilates the time measured in a ‘terrestrial frame’ to the proper time in ‘muon frame’, and mainly that it confuses ‘lifetime’ of a muon and dilation of the ‘time’. <o:p></o:p></i></p><p class=MsoNormal><i><o:p> </o:p></i></p><p class=MsoNormal><i>Therefore, another explanation is proposed based on the CERN results: muons lifetime would be proportional to gamma factor, indirectly to their speed or energy level. It is then shown that restless muons can reach ground level. <o:p></o:p></i></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Best regards<o:p></o:p></p><p class=MsoNormal>Olivier<o:p></o:p></p></div></body></html>
