Re: PROOF God is REAL!
I say that it has 0 rest mass because if the particle did not have motion then it would have 0 mass. The fact that it is moving and has a certain frequency (light has both particle and wave properties) it means it has what is called relativistic mass. Visible light does not pass through curtains because it has a lower energy. UV, x-ray and gamma rays will most definately pass through your curtains hence the reason you can still get skin cancer in places where you are wearing clothes. All sorts of electromagnetic radiation is the same, including visible light.
