Forgive my ignorance if I'm missing something obvious; although I try to stay informed my interest in physics is rather casual. However, I do like to think and speculate about such things based on the knowledge I already have. So with this in mind, I thought I'd just get some feedback on some of these thoughts. What I'd like to know is if there is anything that dismisses the possibility that everything, quarks, electrons, etc., could be made up of photons of varying wavelengths, that when certain conditions are met photons will group together to form what we know as 'mass'. Taking this further, I'd like to know if it is possible that even the fundamental forces could actually be photons; perhaps of such wavelength and properties that we cannot ( yet ) perceive of them? Any thoughts on this? Is there anything that contradicts this completely?
