On the other hand, it may be argued that physicists have been led to this point of view because they refuse to believe what is clearly indicated by some of the most interesting solutions of Maxwell's equations. These solutions show that light-darts of an electrical nature may have a real existence and that it is not impossible for electricity to travel with the velocity of light.
