Last night I had several friends come come over and we got into a discussion about physics. We got to talking about the wave nature of a particle and one of them asked, "If a particle sometimes acts like a wave does that mean it is a wave?" and of course my response, "No it is a particle it's just that some observations see it as a wave.". Later thinking about my response I wondered is that really true. Isn't it possible the exact opposite is true, that it is really a wave and some observations see it as a particle?
