Another probably very retarded question im affraid.Ive only recently been studying all this of my own back so please bare with me. Firstly as i understand it a Photon carries electromagnatism Z and W Bosons carry the strong and weak nuclear forces and the Higgs boson is the missing gravity carrier then what exactly does the Gluon do???? Does it have something to do with the nuclear forces? My next question is how does a boson exactly act? To be honest im a little confused.....does it has any sort of mass, does it sort of attach itself to other particles??? This maybe a bit of a stupid question i understand just need some guidence please.
