However, the model predicts that a universe with a higher dark energy density could achieve a star formation efficiency of 27%. This suggests our Universe, while life-supporting, may not maximize ...

Caption How the same region of the Universe would look in terms of the amount of stars for different values of the dark energy density. Clockwise, from top left, no dark energy, same dark energy ...

For many years, scientists have tried to work out the density of the Universe. The answer to this would give them an idea of whether the Universe is going to expand forever, or if the ...

On the other side of the argument to the big bang was the idea of an unchanging “steady state” universe, the density of which was kept the same by continually adding new matter as it expanded.
