If nature is symmetric, this duality should also hold for matter. Electrons, which we usually think of as particles, may in some situations behave like waves [1]. In addition, dimensions have spaces between them and these spaces are not known how to be fulfilled. Here I show theoretically that wave-particle duality and energy is reflection of the three known dimensions that exist in nature. Also, it is suggested that our universe has more than three dimensions as superstring theory predicts, to reach seven dimensions because the spectrum colors have seven colors that reflect these dimensions. In addition, it is believed that the dimensions move dynamically to fulfill the spaces between the dimensions which are not suggested before as a theory. Moreover, it is suggested that time has three dimensions and not only one dimension because there is three types of motion of the earth that produce time on the earth and they are rotation of the planet on its axis which produces days, the planet orbiting the sun which produces years, and the planet and the sun orbiting the supermassive black hole at the center of the galaxy. http://pubs.sciepub.com/ijp/7/3/4/ijp-7-3-4.pdf dimensions of space dimensions of time spacetime dimensions dynamic dimensions atomic model wave-particle duality the uncertainty principle
