noncommutative deformations of algebraic spaces can drive wave functions to produce the exponential acceleration (inflation) of the Universe.... we have presented a novel framework for understanding the accelerating
expansion of the Universe based on noncommutative quantum gravity. This
model provides a unified explanation for both early inflation and
late-time acceleration without the need for fine-tuning. By introducing
noncommutative deformations to the conventional Poisson algebra, we have
shown that the Universe’s wave function and scale factor can evolve in
ways that align with observed acceleration
This physicist has a very fascinating lucid analysis of why the imaginary number is necessary in quantum physics
The accelerating universe in a noncommutative analytically continued foliated quantum gravity
the noncommutative algebra induces late-time accelerated growth of the
wave function, the Universe’s scale factor, and its complementary
quantum counterpart, offering a new perspective on explaining the
accelerating cosmic expansion rate and the inflationary period. In
contrast to the inflationary model, where inflation requires a
remarkably fine-tuned set of initial conditions in a patch of the
Universe, analytically continued non-commutative foliated quantum
gravity captures short and long scales, driving the evolutionary
dynamics of the Universe through a reconfiguration of the primordial
cosmic content of matter and energy. This reconfiguration is
encapsulated into a quantum field potential, which leads to the
generation of relic gravitational waves, a topic for future
investigation.
Our model provides an alternative to inflationary theories by
explaining cosmic acceleration through a fundamental restructuring of
spacetime geometry rather than relying on specific initial conditions.
: the noncommutative geometry of spacetime itself. This quantum
modification leads to a late-time accelerated growth of the cosmic scale
factor, offering a compelling alternative to dark energy and other
external driving forces.
When we examine the plots of the configuration of matter and energy in the early Universe (see (49) and (51)),
we may identify noncommutative imprints of the spacetime structure
implying non-symmetrical redistribution of matter and energy which
captures, in our conception, the short- and long-range spacetime scales.
Moreover, the transition region between the two universes could serve
as a source of matter/particles and energy, which drives the
acceleration of the Universe.
due to the application of an ‘external’ torque. In the noncommutative
formulation, this symmetry is broken, indicating a mixture of
intensities or amplitudes of the potential . The potential
simulates the presence of different compositions of matter in the
primordial Universe that imply structural modifications of the spacetime
structure, shaping this way its curvature that depends locally on the
amount and distribution of matter or, equivalently, energy. This
symmetry breaking reveals the potentiality of a noncommutative
formulation in terms of its implications in affecting not only the
curvature of space-time, but furthermore, the capture of short and long
scales, boosting the evolution dynamics of the wave function of the
Universe
This suggests that the accelerated expansion of our Universe may be the
result of a folded memory shared by both universes. This concept implies
that spacetime possesses a fold-memory (or twist-memory or
torsion-memory), which, when subjected to a twist in the mirrored
counterpart and subsequently regulated and shaped by this fold-memory,
spontaneously unfolds in response to ‘external’ stimuli. This unfolding
process propels the acceleration of our Universe’s expansion.
A key insight from this formulation is that the introduction of
noncommutative geometry creates a natural asymmetry in the early
Universe, potentially explaining both the inflationary phase and
late-time acceleration without requiring separate mechanisms. The
evolution of the dual spaces, and , reveals a topological twist in the spacetime fabric, which drives this expansion.
the noncommutative symplectic algebraic formulation gives a mechanism
to end inflation and also permits that a non accelerating Universe after
a period of time can start a reacceleration period. This is because the
noncommutative symplectic algebraic formulation induces the capture of
short and long spatiotemporal scales, driving not only the evolutionary
dynamics of the Universe’s wave function and the cosmic scale factor but
also a reconfiguration of matter on small and intermediate scales,

By altering the fundamental scales of spacetime, the non-commutative
structure affects the gravitational field, matter fields, and new stable
quantum states could emerge, expanding the spectrum of new dark matter
candidates, an arena where nonlocal interactions could generate dark
matter condensates, or even reduce or eliminate the requirements for
dark matter. In terms of its effects on current models in the
literature, its implications would be palpable in models based on
modified Newtonian dynamics, running gravitational constants, or
effective dark matter profiles, whose resulting effects could originate
from noncommutative corrections to gravity. Furthermore, the
implications of the non-commutative structure of spacetime in affecting
the dynamics of galaxies would have implications for important
structural elements such as dark matter halo structures and lensing
anomalies in the CBM power spectra due to quantum gravity corrections,
among others. However, more concrete predictions require a fully
developed theory that might provide future insight.

It gives rise to a source term in the background fluid
continuity equation, thereby leading to an apparent type of matter creation picture through the
resulting non-conservation. Remarkably, the resulting Hubble function accounts for the observed
accelerated expansion of the universe without invoking any external dark energy component or
cosmological constant.

Branch-cut cosmology, alternatively,
proposes an absolutely non-temporal beginning in the
imaginary sector, a configuration of pure space, through
a Wick rotation that replaces the imaginary component
of time with the temperature, the thermal time, that
flows in the opposite direction of the arrow of time in the
expansion phases of the first and second scenarios. In the
first scenario, in the contraction phase, before entering
into the expansion phase, the temperature and entropy
of the branch-cut universe must reach values consistent
with the corresponding ones in the expansion phase. For
this to happen, the temperature of the universe in the
contraction phase must increase, but the entropy must
decrease, as determined by thermodynamics, reversing
this way the arrow of time. In the contraction sector of
the first scenario, as the transition region approaches,
there occurs a progressive decrease in the entropy and
an increase in the temperature of the universe, so there
is a critical region, whose dimensions are determined by
the Bekenstein Criterion (de Freitas Pacheco et al., 2023),
where the entropy reaches its minimum value and the
temperature in contra-position its maximum value.
In order to maintain the “past-to-future” global orien-
tation, we propose as a novelty a time arrow oriented
towards the decreasing of entropy in the contraction
sector of the universe, and the conventional concep-
tion in the expansion phase. This proposition would be
valid for both scenarios of the branch-cut cosmology,
as in the first scenario there is a contraction sector fol-
lowed by an expansion phase of the universe, while
in the second scenario all sectors are associated with
the expansion of both, ours and the mirror-universe.
In this conception, the cosmological arrow of time is
determined as the direction in which “time”, from the
macroscopic point of view, flows globally.

The impossibility of packaging energy and entropy
according to the Bekenstein criterion in a finite size
makes the transition phase of the branch-cut cosmol-
ogy very peculiar, imposing a topological leap between
the two phases or a transition region similar to a
wormhole, with space-time shaping itself topologically
in the format of a helix-shape like around a branch-
point (Zen Vasconcellos et al., 2021a), a topic that needs
further investigation in the future.
