Serious academic researchers now believe that particles store information about themselves in a form that increases their mass additional to the known particle masses. This is totally ridiculous. Why does information about a particles's spin need to be written on some kind of massive "nametag" inside the particle? Does it not dawn on them that the information about the spin is stored in the...... fact that it has spin?
