Dark energy is a mysterious force that is believed to be responsible for the accelerated expansion of the universe. It constitutes about 68% of the total energy in the observable universe. Unlike matter, which can clump together under gravitational attraction, dark energy has a repulsive effect on the fabric of space-time, pushing galaxies apart at an increasing rate. The exact nature of dark energy is one of the most profound mysteries in physics; it is not directly observable and is understood primarily through its effects on cosmic expansion and the universe’s large-scale structure. The concept of dark energy was proposed following observations of distant supernovae that suggested the universe is expanding faster than previously thought.
