I was reading about Quantum physics and this really puzzled me. How can an electron move the speed of light? Of course, I’m assuming an electron has mass whereas a photon does not, and I understand that the issues is more about all possible trajectories of an electron needing to be averaged to determine it’s possible position and velocity. But still, wouldn’t some trajectories be nullified due to the inability of anything with mass to travel the speed of light? Or maybe I’m just a moron and my question is flawed!
