"The Dark Energy"

Dark energy is a mysterious force that makes up about 68% of the universe and is driving its accelerated expansion. Unlike matter or dark matter, which exert gravitational pull, dark energy acts as a sort of "antigravity," pushing space itself apart. We can't see or measure it directly, but its effects are observed through the increasing speed at which galaxies are moving away from each other. Although its exact nature remains unknown, dark energy plays a crucial role in shaping the universe's large-scale structure and fate.
