In my viewpoint, it’s all a matter of perspective. Gravity SEEMs like a very strong force to us, but in reality it’s quite weak. When you get to the subatomic levels, some weak forces are stronger than gravity which has strength we run into every moment of every day.
Added to that: Scientists might be finding NEW forces at these levels.
From what I remember neutrons have 2 down quarks and protons have 2 up and 1 Dow quarks. This brings up several questions, Do quarks, if so are they doing so in the nucleus? Or is it only the glueons, that holds the strong force? Always wondered about what holds the strong force, nucleus together. I had not considered gravity, because I thought of it as a macro force, I will have to read up on it, thanks for your thoughts.
