The universe, currently estimated at about 13.8 billion years old, is projected to reach its end or 'death date' in 33.3 billion years. A new cosmic model from US and Chinese researchers indicates that after approximately 19 billion more years, dark energy will weaken, allowing gravity to cause all matter to collapse into a single point. This marks a significant shift in understanding the universe's longevity, challenging previous beliefs of limitless expansion. Current estimations suggest that about 68.3 to 70 percent of the universe is influenced by dark energy.
Researchers predict that the universe will reach its 'death date' at 33.3 billion years old, with approximately 19 billion years remaining before a Big Crunch occurs.
The current age of the universe is about 13.8 billion years, suggesting a finite lifespan as it eventually succumbs to gravity after dark energy diminishes.
