Simple! There are only 3 kinds of mass:
- “Newtonian” mass
- “relativistic” mass
- “quantum” mass
What is it that makes one particle light and another heavy? The origin of mass is one of the most intriguing mysteries of nature.
Some particles, such as the W boson (which carries the weak force) have so much mass they barely move, while others, like the photon, are entirely massless and zip around at the speed of light.
The mass of fundamental particles – those that carry forces and build nuclei and atoms – is often explained by the way they move through the Higgs field that is thought to pervade all the space of the Universe.
To some particles, such as the top quark, the Higgs field is like molasses: they get bogged down and become very heavy. To others, like the photon, the field is empty space: they fly through unimpeded and gain no weight at all.
