Dark energy and dark matter are placeholders for something we at present cannot define.
At actual absolute zero there is no movement/thus no energy.
Even the fundamental forces of the Universe as we understand them break down if there is no 'force carriers'
In quantum field theory, force carriers or messenger particles or intermediate particles are particles that give rise to forces between other particles. These particles are bundles of energy of a particular kind of field. There is one kind of field for every type of elementary particle.
Quantum field theories describe nature in terms of fields. Each field has a complementary description as the set of particles of a particular type. A force between two particles can be described either as the action of a force field generated by one particle on the other, or in terms of the exchange of virtual force carrier particles between them.
The energy of a wave in a field (for example, electromagnetic waves in the electromagnetic field) is quantized, and the quantum excitations of the field can be interpreted as particles. The Standard Model contains the following particles, each of which is an excitation of a particular field:
Gluons, excitations of the strong gauge field.
Photons, W bosons, and Z bosons, excitations of the electroweak gauge fields.
Higgs bosons, excitations of one component of the Higgs field, which gives mass to fundamental particles.
In addition, composite particles such as mesons, as well as quasiparticles, can be described as excitations of an effective field.
Gravity is not a part of the Standard Model, but it is thought that there may be particles called gravitons which are the excitations of gravitational waves. The status of this particle is still tentative, because the theory is incomplete and because the interactions of single gravitons may be too weak to be detected.

At AZ, everything is frozen, there can be no excitation of particles.
No excitation, no force carriers, the Standard Model breaks down.
In cosmology there are what is called 'Voids'. Voids are black areas of the Universe where 'no data' is collected.
From a science view, Dark is void.
The Boötes void is one of the largest-known voids in the Universe, and is referred to as a supervoid.
The eye registers dark as black. Since the eye can't resolve the entire spectrum it sees dark as no data.
The Hubble Deep Field proves the dark one sees when looking at the Universe is not void.
Thus, dark is a matter of relativity.
