Can the study of deep space objects tell if the universe is finite?

A big job for the Supernova

The discovery of a Type Ia supernova five million light years away may finally answer the question of whether the universe is finite or infinite. All type Ia supernovas regardless of distance emit the same amount of light at a constant rate, which means that they can be used to figure out the distance and velocity of objects in deep space. For those who don't know, if an object in deep space is found to be travelling at a velocity lower than a nearby object, the universe is most likely finite.
