    Does my mirror reflection have mass? What about your shadow?

    "Your mirror reflection" is not a well-defined object (same for the shadow). Asking if it has mass is about as meaningful as asking "does the color red have mass?".

    That makes sense. I am not involved in Physics in anyway, it was just something that I was curious about. Thank you.

    Optical images do not consist of matter so the answer has to be no. Interestingly, your image can be seen to bump into other images and knock them over. Now there's a thought. :smile:

    damn daemons, they always disappear in a laboratory setting, that's why we can't scientifically conduct experiments on ghosts :wink:
