Scientists may have found a way to estimate the end of the universe. For decades, astronomers believed the expansion of the universe would continue forever. But new observations of dark energy are challenging one of the most important assumptions in modern cosmology. Recent DESI measurements and supernova observations suggest dark energy may not behave exactly as scientists expected. And in one new cosmological model, the expansion of the universe eventually slows, stops, and reverses. The result would be a Big Crunch — a future in which space contracts and the universe becomes increasingly dense and hot. Even more astonishing, the model gives the universe a possible total lifetime of roughly 33 billion years. Since the universe is already around 13.8 billion years old, that would place the final collapse roughly 20 billion years into the future. But is this really how the universe will end? In this video, we explore dark energy, DESI, the Big Crunch, the fate of the universe, and the
