On a science blog I read a question asking about light passing thru a vacuum and how this was possible. If light, as the subject cannot be defined as a particle and therefore cannot be "charged or magnetic " as an electron but defined as a wave. If it is a wave then light becomes a series of wave structures flowing from the emitter to the collector. As an oscillating EMF nears 100 thousand hertz it begins to radiate from the conductor and travels in a nearly straight path. However, an electric, magnetic or some physical object can change its path. It seems that the "wave" is like a balloon, and its path and properties can be changed. The operative concept in the question is, "VACUUM". Starting with space, sometimes is assumed to be a vacuum. Space is not a vacuum. The term vacuum generaly refers to a lower atmosphere pressure which is retained, "vacuum packed" or a moving low pressure moving atmosphere as a vacuum cleaner neither of these is empty. A nearly perfect vacuum can be formed and it does not stop light, or electric / magnetic lines. Because EMPTYNESS is not a blocker.  Light  and free radiated fields do not need a carrier. It may be due to the ultra-ultra high frequency of light giving it high speed and no real inividual wave mass power.
