Force, Big Bang, Black Hole

Kant suggests that in the absence of a counter-force, Repulsion would effect infinite expansion, and that Attraction would effect contraction to a point. What seems erroneous in the latter is that since matter is infinitely divisible, the contraction that Attraction would effect would, likewise, be infinite.  Furthermore, what he misses in both possibilities is that each would occur instantaneously, since any time-lapse would imply the presence of a counteractive force.  So, a 'big bang' and a 'black hole' are not so much actual events but imaginative approximations of the two theoretical extremes, i. e. of Repulsion and Attraction, respective, taken in isolation.
