I would like to understand better the concept of radiation pressure, my main confusion comes from the fact that if the Stress-energy tensor for electromagnetic radiation is traceless, that would imply the pressure components of the tensor equal zero, and yet it's obvious radiation exerts pressure when absorbed or reflected and radiation pressure plays an important role in star dynamics.
I must be missing something really basic here, can someone explain this to me?
Thanks
