If gravity is one of the weakest natural forces, then why is it the dominate force in space?

Orbits act and react because of gravity. Stars collapse, some into black holes, because of it. Galaxies and galaxy clusters are bound by it. How is this so if it is the, or one of the, weakest natural force?

EDIT: Okay, I think I get why gravity is the dominating force for long distances. Now I'm trying to understand how the strong and weak forces are bound by mass. ELI5 would be great.

Because there are only two infinite-range forces, EM and gravity.

Moreover, in EM opposite charges are strongly attracted to form neutral states where the positive and negative charges cancel. So large systems will almost always be electrically neutral.

Gravity is essentially all that's left above a certain scale.
