  • @MultiGalmeida they have momentum, f=dp/dt

  • If gluons attract each other for their charge, how can you predict that attraction without some sort of "bent space" since they have no mass? I mean, I don't know how to measure how a force acts on something which has no mass, except that way it was done with light and gravity

  • Can't we make A spaceship that goes light year speed with that knowledgeably?

  • isnt the weak force the only force which particles have mass?
