WebDark energy is a mysterious and enigmatic force that is believed to be responsible for the accelerated expansion of the universe. Despite the fact that it is responsible for the … The accelerated expansion of the universe is thought to have begun since the universe entered its dark-energy-dominated era roughly 5 billion years ago. [8] [notes 1] Within the framework of general relativity , an accelerated expansion can be accounted for by a positive value of the cosmological constant Λ , … See more Observations show that the expansion of the universe is accelerating, such that the velocity at which a distant galaxy recedes from the observer is continuously increasing with time. The accelerated expansion of the See more Dark energy The most important property of dark energy is that it has negative pressure (repulsive action) … See more • Cosmological constant • Friedmann–Lemaître–Robertson–Walker metric See more In the decades since the detection of cosmic microwave background (CMB) in 1965, the Big Bang model has become the most accepted … See more To learn about the rate of expansion of the universe we look at the magnitude-redshift relationship of astronomical objects using standard candles, or their distance-redshift relationship using standard rulers. We can also look at the growth of large-scale structure, … See more As the universe expands, the density of radiation and ordinary dark matter declines more quickly than the density of dark energy (see equation of state) and, eventually, dark energy dominates. Specifically, when the scale of the universe doubles, … See more
