The Role of Dark Energy

Dark energy plays a crucial role in the universe's expansion, which is accelerating, but its true nature remains unknown. Unlike regular matter, dark energy causes galaxies to move apart, and its unpredictable characteristics could dictate the universe's eventual fate. There is speculation that dark energy might be a constant property of space or something that changes over time, and understanding it is pivotal in determining how the universe will end. The lack of clarity surrounding dark energy makes it an intriguing and challenging topic for scientists looking to unravel the mysteries of cosmic evolution.
