The universe is often depicted as a vast expanse of mostly empty space, dotted with galaxies, stars, and planets. What’s truly fascinating is not just the composition of this vast cosmos, but its behavior over time. For decades, the consensus among astronomers was that the universe, though expanding, must be slowing down due to gravitational forces. However, the groundbreaking discovery in the late 20th century turned this notion on its head—the universe's expansion is not decelerating; it’s accelerating. This article explores the enigmatic forces at play and the implications of an ever-accelerating universe.
