About the expansion of universe my view is that as sum of mass and energy of the universe is constant so as the stars keep on giving out radiation and loose mass their velocity will increase accordingly with the law of conservation of linear momentum which states that m1v1=m2v2 where m1v1 and m2v2 are mass and velocity of any object in initial and final state . So if a star is loosing mass than to satisfy the law of conservation of linear momentum it`s velocity must increase . As the space is empty it does not provide any frictional force on the accelerating star and so as the star keep on giving out radiations it`s mass keep on decreasing and it`s velocity keeps on increasing indefinately .Any thing which can control the velocity of hevenly bodies is gravitational pull between them but as gravitational pull is inversely propotional to square of distance between bodies so as the stars or galaxies moves apart the gravitational pull between them also decrease and hence favouring accleration of heavenely bodies.
