Ok, I understand that it is about those negligable probabilities that end up happening, but b/c we don't live long enough to see these probability happen in our real life(big objects take longer time), we have seen that quantum tunelling exist on nanoscopic level. Now, what I don't understand is that how is it possible? I know it has been proven, and makes sense by probability but still. I guess it just bothers me to see something happening that is not supported by our physical laws. I believe everything happens for a reason(causuality) but this counters it.
