    Does light weigh anything?

    Things such as light that have no rest mass cannot be put on a scale to be weighed, so they have no weight (but they do have mass, if you take the energy into account). Mass and weight are not the same. You don't feel weight when you're floating freely in space, but you then still have mass, otherwise the force of gravity would not keep pulling you down and/or keep changing the direction of your movement.

    No, because 'light' is not a thing.

    1. What we experience as light/shadow/color is an observer dependent sensation.

    2. This subjective (observer dependent) sensation is mediated by wave-motion propagating through a medium of sub-atomic particles (commonly known as 'aether').

    3. Therefore 'light' cannot be weighed because light is only a sensation much like sound, hot, cold, etc. are sensations. Perhaps you could find a way to 'weigh' the aether particles, but definitely not light.

    No. Light is made of photons and photons do not have mass.
