What happens if the universe is below critical density?
If the density of the universe is less than the critical density, then the universe will expand forever, like the green or blue curves in the graph above.
What is density of universe?
The mass density of visible matter (i.e., galaxies) in the Universe is estimated at 3e-28 kg/m^3 (3e-31 times the mass density of water).
Why is the density of the universe important?
Comparing the critical density to the actual density can help scientists to understand the cosmos. If the actual density of the universe is less than the critical density, then there is not enough matter to stop the expansion of the universe, and it will expand forever.
