The Short Answer

The matter and energy in the early universe was extremely smoothly distributed. If it had been lumpier, certain regions would've collapsed into black holes, but because the matter was so smoothly distributed the outwards pull was equal to the inwards pull, preventing a collapse In fact, the reason any regions collapsed into stars and galaxies at all was because of tiny initial fluctuations in roughness that are predicted by cosmic inflation theory, which blows up tiny quantum fluctuations to huge size fluctuations in density. These would provide the initial roughness needed for the formation of all structure in the universe
