Universe may end in a “big crunch,” new dark energy data suggests

A Cornell physicist has calculated that the universe may be nearing the halfway point of a total lifespan of about 33 billion years. Using newly released data from major dark energy observatories, he concludes that the cosmos will continue expanding for roughly another 11 billion years before reaching its largest size. After that, it would begin to shrink, eventually collapsing back into a single point, much like a stretched rubber band snapping back.
