Summary

Exploding stars seen billions of light-years away have given a preliminary verdict: Gravity will never be able to halt the universe's expansion. Two groups of astronomers have analyzed light from these remote cataclysms to estimate their distances and determine how fast the stars were rushing away from Earth billions of years ago when they exploded. Their results imply that the universe contains far less mass than many theorists had hoped.
