We are told that at the start of the Solar System, grains of dust coalesced 
together to form larger particles.  What was the force that held these dust 
particles together?  Was it gravity?  But we are told that gravity is the 
weakest force in nature, so how would the first dust particle have enough 
gravity to attract and stick to the next particle of dust?
