Does dark energy have gravity?

That is fine. This is an answer to what dark energy is, why it has a constant energy density, and whether it has gravity. As for whether or not dark energy can fall into a black hole, that is more complicated. From the point of view of modifying gravity, dark energy is not something that can fall into a black hole.

What is Dark Energy, and how was it discovered?

Dark Energy is supposed to substantiate the theory of cosmic inflation; the substance itself is a hypothetical one.There is also a little controversy, though: Albert Einstein provided the idea with his cosmological constant but without evidence it fell by the wayside - the result being its exclusion from certain fields of physics, while still being useful to others, bringing about a

$begingroup$ Actually, the first law of thermodynamics proves that dark energy cannot remain at constant density despite the expansion of the universe, if it behaves like all other forms of energy that we know about. All other forms of energy have gravity, as they warp space/time by their existence, all forms of propulsion have limits. The gravity of dark energy itself will collapse the

Dark energy – a mysterious force driving the ever-expanding

Phantom Energy: The concept of phantom energy posits that dark energy could have a negative pressure and an equation of state parameter less than -1.

What is Dark Energy? Inside our accelerating, expanding Universe

Some scientists think that dark energy is a fundamental, ever-present background energy in space known as vacuum energy, which could be equal to the cosmological constant, a mathematical term in the equations of Einstein''s theory of general relativity. Originally, the constant existed to counterbalance gravity, resulting in a static universe.

Age of a dark energy dominated universe

That''s the sense in which the Universe would be infinitely old (assuming it was always dark energy-dominated). It''s also worth noting that an eternally dark energy-dominated Universe is static. Its density is constant in time, and its metric can be written in a manifestly static form. Since there is no evolution, the Universe can have no beginning.

Dark Energy and Conservation of Momentum

One well-explored explanation to dark energy is "quintessence": the idea that dark energy is some sort of scalar field like the Higgs field or the inflaton field. Fields are characterized by their ability to vary from place to place, and in this sense, scalar field dark energy is not much different from ordinary matter.

cosmology

Since energy density goes ~Energy^4 that''s a mere 2 orders of magnitude apart. In addition, according to PDG total neutrino average number density today is: n(ν) = 339.5 /cm^3 which in turn with a value of 0.1 eV for neutrino energy gives an energy density ~ 1E-11J/m^3, again close to vacuum energy.

Can dark matter be converted to dark energy?

Thus, dark matter behaves gravitationally as "normal matter", while dark energy causes accelerated expansion. That is, more or less, all that we know about dark matter and dark energy.

Why is dark energy called dark?

There are two main reasons why dark energy is called dark. The first one has to do with the fact that all detections of its effects are indirect.For example, we use the spectra of Type Ia supernovae as standard candles to verify the hypothesis that further galaxies are receding from us at increasing speeds.. This accounts for the observational side.

What are the units of dark energy?

Popular literature seems to equate dark energy with the cosmological constant of the Einstein field equations. We know however that the dimensions of any constituent of the field equations is ${rm length}^{-2}$, and that the metric tensor itself is dimensionless.This means that the dimensions of the cosmological constant are ${rm length}^{-2}$.

Dark energy and light red shifting

Is the amount of energy that dark energy applies to push objects apart equal to the amount of energy lost because light from distant galaxies is red shifted?. No, dark energy existed prior to the expansion and the shift towards blue or red is based on the direction of movement of the emitter relative to the observer, so the amount isn''t equal.
