I haven't studied physics, but I've had this thought in my head lately and I want to get it out. I'm hoping someone here can either help me understand this or set me straight if I'm on the wrong track. I've been mulling over wave particle duality in my head, and I realized that Einstein sort of showed us a duality as well in E=mc2. Basically, I'm wondering if while no one is really observing a particle it is present in an equilibrium of energy and mass potential, so it is a wave and a particle at the same time, but when you try to observe it via its mass the energy is converted to mass temporarily, so that the wave form collapses. Conversely if we had a way to observe the particle by its energy, then the mass would be converted to energy and temporarily the particle would disappear - leaving us with a wave. I'm thinking its balanced between energy and mass normally, but if you check one side of the duality then you force all of the potential energy to that side of the duality and end up with a wave or a particle. Does that make any sense at all? Are wave/particle duality and E=mc2 related? Am I totally thinking in the wrong direction?
