What would the universe be like if the fundamental unit of charge were about 20 times larger?

Question

I mean the charge of the electron, positron, proton, charged mesons, etc.

Answer 1

It would be the same.

Answer 2

I doubt we would be around to see it.

The atom would be much smaller.  This means we would be smaller, the earth would be smaller, gravity would be bigger.

Electromagnetic radiation from the atoms would be at a much higher frequency.  Ionization energies would be higher.

It is possible that atoms would not fuse.  All atoms except for H1 and H2 would be radioactive because of the balance between the strong, the weak and the EM forces.

Molecular bonds would be much stronger  (although they might just be H-H atoms).  They would break at much higher temperatures.

It is also possible that electrons might be captured by protons thus creating a dynamic equilibrium between protons and nuetrons.

Don't know anything about the standard model, but charge gets pluged in there.  Might affect other properties.
