Didn't Einstein say that mass and energy were interchangeable quantities?
Electromagnetic waves transport energy - Does this therefore mean they also transport mass?
Could, therefore, all the radiation coming out of every decaying atom in the universe, every star and every accelerating charge (gaining kinetic energy) not cause some large scale gravitational effects that could explain dark matter?
I also thought that this could mean in places where different EM waves from different star systems happened to superimpose there could be greater mass. The amount of dark matter in a galaxy would be proportional to the number of stars in it then I suppose, and things like E=hf mean x-rays would be "heavier" etc...
