Did you know that the universe is expanding at an accelerating rate? This cosmic phenomenon was discovered in the late 1990s and has puzzled astronomers ever since. The driving force behind this acceleration is known as dark energy, a mysterious form of energy that makes up about 68% of the universe. Despite its dominance in the cosmic budget, we know very little about it. Its discovery has reshaped our understanding of the cosmos and opened up new avenues of research. As scientists continue to study dark energy, we may be on the brink of uncovering secrets that could revolutionize our knowledge of the universe. Keep looking up, the cosmos has so much more to reveal!
