    Would anyone please explain with some back up about this whole "Force-carrying-particles" thing is?

    mmm, where is William when you need him?


    As is often the case with technical subjects we are presented with an unfortunate choice: an explanation that is accurate but incomprehensible, or comprehensible but wrong.

    force-carrying particles are the particle that...well, carry the forces. You could also say they "mediate" the forces between other particles. The force carrier particles are photons (EM force), W<sup>+</sup>, W<sup>-</sup>, and Z<sup>0</sup> bosons (weak force), gluons (strong force), and gravitons (gravitational force; yet to be discovered). All of these particles are bosons, with a spin of 1, or 2 for gravitons, should they be discovered. Photons carry the electromagnetic force between electrically charged particles, the W and Z bosons mediate the weak force and can change the flavor, generation, spin, and momentum of other particles. Gluons carry the strong force between quarks in a baryon or meson and are somewhat responsible for the binding of nucleons into a nucleus. I don't know how much info you wanted on the force-carrying particles, but I can go on, if you'd like...
