Figure 5. The S’ reference frame has a velocity v in the positive X axis direction. The man and the S reference frame are at rest. Also, an impenetrable barrier is at rest in the S frame and a bullet (particle wave) will tunnel through the barrier to the left via the here-now of the S’ frame. The difference between the two frames along the width of the barrier is T" to the right and –T" to the left. Consequently, the particle wave will tunnel into the past relative to the man.
