If the average mass density ρ₀ had been greater than the critical density ρ_c in the early universe, what might have been the likely result? A)The universe would have expanded very rapidly, and matter would not have clumped together to form galaxies. B)The universe's mass would have clumped together in a relatively short time and collapsed to a singularity like that from which it emerged. C)Cosmic inflation would not have occurred. D)The cosmic microwave background radiation would not have been created.

If the average mass density had been greater than the critical density in the early universe, gravitational forces would have dominated, leading to a rapid clumping of matter and potentially causing the universe to collapse back into a singularity, rather than expanding and forming galaxies.
