Hello, I am a Msc Computer Engineer who is dealing with physics as a hobby. I have read some books about quantum physics. But I am not technically professional on equations and general scope of quantum physics. I was recently thinking of why a photon is moving a sinusodial trajectory in space. If the space is in 3 dimension, a single particle should move on a linear trajectory. I strongly believe that the space has a forth dimension which is a spehere at every (x,y,z) points. and this dimension interacts with some particels such as photos by chaging its directions. And every particle (some people may call it a string from superstring theory) has two property P1 and P2. If P1 of the particle is high the 4th dimension will change its direction much, if P2 is high but this time the dimension will respond in change less. P1 will affect amplitude of the particle and P2 will affect the wavelenght. I cannot state what i think in equations but i believe the tracjectory of a photon under these circumstances is like the image below http://www.buyutec.net/data/media/88/yay.jpg By this approach, if P2 is too high thus making the wavelength of a photon zero will lead to the creation of a mass. Close string Is there any known issue like this approach?
