In quantum tunnelling,as I understood,when a particle reaches the boundry of a potential barrier,it is possible,that the particle passes the barrier and it is performed like disappearing before the barrier and appearing after it.If the latter is the case,so there should be a motin which is faster than light.But it can't be correct.
Another problem is that the probability for the presence of particle in the middle of the barrier,is not zero.I think it means that the particle just moves inside the barrier and then outside of it.But it can't be correct too because the particle can't do that because of the high pottential difference.
Its so much confusing.Could you help?
thanks
