The only way to answer ill-founded questions is to point out that they are such. Unfortunately you are propagating the misconceptions by acting as if the original question made sense, by granting the assumption that a force pushed apart the universe (absurd) but resolving the situation by...
Just recently, I heard that at the speed the galaxy is currently spinning gravity alone is not a strong enough force to hold everything together. If that is true, what is the extra force that keeps the galaxy together?
you are just pick apart his question, and not answering it. assuming he is referring to the force that pushed the universe apart "the big bang," what should the outcome be there is an opposite and equal reaction to that force?
thanks for actually answering the question:]
