The Accelerating Universe

The accelerating universe refers to the discovery that the expansion of the universe is speeding up over time. Scientists observed distant galaxies and found they are moving away faster than expected, indicating some unseen force, called dark energy, is pushing everything apart. Think of it like a balloon being inflated—more rapidly as it expands. This means the universe isn't just expanding, but doing so at an increasing rate, impacting our understanding of its future and the fundamental forces shaping cosmic evolution.
