"WHY IS GRAVITY WEAK??"
It ISNT!!
If it was,things wouldnt be held down like they are!
Consider this: You can throw a ball into the air with little effort, even though you are being resisted by a whole planet's worth of gravity. Gravity is exceedingly weak compared to all the other forces.
Any time you get something for nothing, it means that someone, somewhere, got nothing for something.
