I'm having trouble understanding how light travels as waves and particles. I think it should be one or the other and not both. I'm thinking that light travels only as particles and only linear. The fact that light wraps around things is due to the lensing effect that light does naturally. We can see this if you take a flashlight and point it at something solid that light cannot pass through and if you move the light source closer or farther to the object, the shadow changes, due to the lensing effect as a normal property that light has. Wouldn't this mean that there is no such thing as gravitational lensing? That the redshift is just due to the lensing effect happening at high speed? There was an experiment that one guy did to show the redshift with rotating mirrors, but again isn't that just at high speed? That would also be why light can be split or focused. If it were to travel as waves, and we tried to split it, it would then be split to nothing or focused to nothing. I could be wrong about this. This is just what makes sense to me.
