1.   And the discovery of ever-larger galactic superclusters seemed to defy explanation if omega does equal one.

2.   If omega equals more than one, then the universe would collapse of its own weight, contracting in what is called the Big Crunch.

3.   In short, at the critical density, expressed as omega equals one, the universe would be in a state of equilibrium between collapse and eternal expansion.

4.   Scientists express this condition of critical density as omega equals one.

5.   Such an equilibrium, which has appealed to cosmologists on the grounds of both theory and esthetics, is expressed as omega equals one.
