Possible candidates include a cosmological constant and quintessence.
The big question in cosmology is whether or not the dark energy is just a cosmological constant.
Einstein considered this introduction of a cosmological constant the greatest error of his life.
For example, it should be able to tell us if dark energy is just a cosmological constant.
If dark energy is a cosmological constant, this ratio should be constant in both cosmic time and location.
S he simply fudged his formula with what he called a cosmological constant.
Space with a cosmological constant is qualitatively different: instead of moving outward, the cosmological horizon stays put.
For example, we will know if dark energy is a cosmological constant.
Most astrophysicists believe that dark energy is a cosmological constant; or, an intrinsic property of space itself, which has a negative pressure driving space apart.
The energy of the field in those regions would behave like a cosmological constant.
Well, it produces a Cosmological Constant, that would cause the universe expansion not to slow down over time, as any sensible universe should do, but to speed up over time.
There once was a man who referred to his prediction of a cosmological constant as the single"biggest blunder" of his career.
Many researchers believe that the energy of the vacuum simply has some particular value,dubbed a“cosmological constant”.
One version of Einstein's gravity theory,the version that contains a cosmological constant, predicts that"empty space" can possess its own energy.
When the volume of the universe doubles, the density of Darkmatter is halved but the density of dark energy is nearly unchanged(it is exactly constant in the case of a cosmological constant).
This idea originally came from Albert Einstein,who added it as a"cosmological constant" to his theory of general relativity.
Today this is largely carried out in the context of the CDM model, where the Universe is assumed to contain normal(baryonic) matter, cold Dark matter,radiation(including both photons and neutrinos), and a cosmological constant.
It further provided support that the expansion of the universe could be explained by a cosmological constant, as proposed by Einstein in his General Theory of Relativity.
In such a universe,in which the expansion was accelerated by a cosmological constant rather than slowed down by the gravitational attraction of matter, there would be enough time for light to travel from one region to another in the early universe.
In order to remain consistent with a steady state universe,Einstein added what was later called a cosmological constant to his equations.
In order towork out such a solution, he introduced into a cosmological constant Λ(lambda) the gravitational equation, with an added dimension of force, to compensate for gravity.
Inflation answers this question by postulating that all the regions come from an earlier era with a cosmological constant(big vacuum energy).
Physicists have postulated the existence of dark energy,appearing as a cosmological constant in the simplest gravitational models, as a way to explain the acceleration.
Lucas Lombrizer, Assistant Professor of Theoretical Physics at the University of Geneva in Switzerland,introduced a new way of estimating Albert Einstein's gravity equations to find a value for a cosmological constant that closely matches its observed value.
In cosmological terms,the quantum corrections can be thought of as a cosmological constant term(without the need for dark energy) and a radiation term.
In general relativity,scientists account for the accelerated expansion of the universe by introducing a mysterious form of matter called dark energy- the simplest form of which may be a cosmological constant, whose density is a constant in space and time,” said physicist Baojiu Li of Durham University.
Ali and Das explain explain that the quantum corrections can be thought of as a cosmological constant term(without the need for dark energy) and a radiation term.
Viewing the solution this way, the probability that one of these universes has a cosmological constant that is as small as is indicated by current experiments is actually non-zero.
The contours encircle the values of the matter density anddark energy(in the form of a cosmological constant) that best fit the supernova data(in units of the critical density of the Universe).
In General Relativity,scientists account for the accelerated expansion of the universe by introducing a mysterious form of matter called dark energy- the simplest form of which may be a cosmological constant, whose density is a constant in space and time," says Baojiu Li, also of Durham Institute for Computational Cosmology.
