Dark energy is a mysterious force driving the accelerated expansion of the universe.
Dark energy, comprising approximately 68% of the universe’s energy density, remains an enigma in cosmology. Unlike dark matter, which exerts gravitational pull on visible matter, dark energy works in opposition to gravity, pushing galaxies away from each other and driving the accelerated expansion of the universe. Its elusive nature and unknown origin present a profound challenge to scientists. The discovery of dark energy in the late 1990s was a groundbreaking revelation, and it continues to be a subject of intensive research as astronomers seek to unravel the fundamental nature of this perplexing cosmic force.
