Point A to Point B

[enkinight]

It traveling at the speed of light, If an electron met a point of action in space(e.g. interacting with some other particle) and then went to point B the next place of interaction would the space inbetween these two points matter if there was no information to interact with in this space? <br />I guess my question is.... is space relevant as a distance traveled if there is no interaction/information with in it?<br />Especially for light speed wouldn't things at this speed only be concerned with one interaction to the next? <br />In my opinion this could explain the tunneling effect seen in sub atomic particles.
