Could Cosmic Acceleration Be a Phase-Synchronisation Effect?

Introduction
The accelerated expansion of the Universe is normally attributed to dark energy, often represented by a cosmological constant. I would like to suggest a different physical possibility.
Suppose gravitational interaction is connected to the phase relationship between oscillating matter and underlying fields. At relatively short astronomical distances, matter may remain sufficiently synchronised for the interaction to appear as ordinary attractive gravity. At very large distances, propagation delays could produce increasing phase differences.
If phase affects the direction or magnitude of the resulting interaction, sufficiently large phase differences might weaken gravitational attraction or even produce an effectively repulsive interaction.
This idea leads to a potentially testable astronomical prediction.
A Simple Physical Analogy
There is a well-established phenomenon in fluid mechanics known as the secondary Bjerknes force.
Two pulsating bodies immersed in a fluid generate pressure waves. Their interaction depends upon their relative phase. Under appropriate conditions, bodies pulsating in phase can attract, while bodies pulsating out of phase can repel.
The importance of this example is not that gravity is literally a Bjerknes force. Rather, it demonstrates a physical principle:
Oscillating systems communicating through a medium can experience attraction or repulsion according to their phase relationship.
This raises an interesting question.
Could something conceptually similar occur between matter and fundamental fields?
Applying the Principle to Gravity
Consider two galaxies separated by a relatively small cosmological distance.
If the relevant field oscillations associated with the two systems remain synchronised, their interaction could be attractive. We would observe this as gravity.
Now increase their separation enormously.
If information or disturbances in the relevant field propagate at a finite velocity, increasing separation introduces an increasing propagation delay.
The sequence would then be:
increasing distance → increasing propagation delay → increasing phase difference → changing interaction.
At some separation the systems might remain largely in phase and therefore attractive.
At another separation their phase difference could weaken the attraction.
At still greater separation the phase relationship might cross through a neutral point and eventually become effectively repulsive.
This offers a possible physical interpretation of cosmic acceleration without initially assuming a separate repulsive substance or energy component.
An Important Difference from Uniform Dark Energy
There is an immediate consequence.
Galaxies are not all separated by the same distance. Nor do they necessarily have identical histories or environments.
Therefore, if cosmic acceleration results from a phase-dependent interaction, I would not expect every distant system to show precisely the same effective acceleration.
Instead, the effect could vary with separation and possibly direction.
In its simplest conceptual form, increasing separation might produce a sequence such as:
attraction → weaker attraction → neutral → repulsion → maximum repulsion → neutral → attraction
and potentially repeat if phase continues to accumulate.
The actual relationship need not be a simple sine wave. That would depend upon the underlying field dynamics. The important prediction is that the residual should contain structure associated with phase, rather than simply a constant repulsive effect.
An Observational Test
This leads to what I believe is the most important question raised by the hypothesis:
After accounting for known matter distributions, peculiar velocities and conventional gravitational effects, do residual galaxy or supernova motions contain a systematic oscillatory dependence on distance or redshift?
If the synchronization hypothesis is correct, the residual expansion data might contain preferred distances at which the apparent additional acceleration becomes stronger, weaker or changes sign.
This should be distinguishable, at least in principle, from a cosmological constant producing a smooth background effect.
Existing Type Ia supernova and large-scale galaxy survey data may already be sufficient to search for such a signature.
A useful analysis might therefore take residuals from a standard cosmological fit and test them for statistically significant periodic or quasi-periodic structure as a function of comoving distance or redshift.
Direction could also be examined. If synchronization depends upon propagation history and the surrounding field environment, the effect may not be perfectly isotropic.
Falsifiability
An important advantage of making the prediction in this form is that the hypothesis can fail.
If sufficiently accurate cosmological observations show no phase-like or distance-dependent residual after conventional effects and observational biases have been removed, then this simple version of the synchronization mechanism would be strongly constrained.
Conversely, a reproducible oscillatory residual would not by itself prove synchronization theory. Conventional astrophysical effects, selection biases and alternative cosmological models would first have to be excluded.
But such a finding would provide a reason to investigate whether a phase-dependent physical mechanism could be involved.
Conclusion
The proposal can therefore be reduced to a relatively simple idea:
Matter generates or participates in oscillations of underlying fields.
Propagation over distance introduces phase delay.
Relative phase affects the resulting interaction.
At cosmological distances, desynchronisation could therefore modify gravitational attraction and potentially appear as cosmic acceleration.
The Bjerknes effect demonstrates that phase-dependent attraction and repulsion can occur in a physical wave system. I am proposing that we ask whether an analogous principle, operating in fundamental fields rather than a fluid, could leave a measurable signature on cosmological scales.
The crucial issue is therefore not whether the analogy is appealing, but whether the predicted pattern exists in astronomical observations.
