Accelerating Universe

The accelerating universe refers to the observation that the expansion of the universe is speeding up over time. This means galaxies are moving away from each other faster than before. Scientists believe this is driven by a mysterious form of energy called dark energy, which makes up about 70% of the universe. Unlike gravity, which pulls objects together, dark energy pushes space itself apart. This discovery has profound implications for understanding the universe’s fate, suggesting it may continue expanding forever at an increasing rate.
