SUMMARY
In the discussion, it is established that most elementary particles in the Standard Model possess mass, with the exception of gluons and photons, which are massless. This leads to the conclusion that since all matter is composed of these massive particles, everything in the universe, except for light, has mass. The inquiry was sparked by a video titled "How Much Does a Shadow Weigh?", highlighting the relationship between mass and the fundamental particles of the universe.
