I wanted to pitch an alternative cosmological model to spark some discussion and get feedback on its mechanics. I am trying to approach the problem of cosmic expansion from a "pull" perspective rather than an internal "push," and I think recent astrophysical findings might offer a loophole.

What if cosmic expansion and the continuous widening of the cosmic vacuum are driven by a massive, omnidirectional network of black holes distributed uniformly at or beyond our observable cosmic horizon?

In this scenario, we wouldn't have a single black hole sucking everything toward a central point. Instead, a vast distributed web of black holes would create a collective negative pressure gradient. This external gravitational gradient would pull the fabric of space-time outward smoothly in every direction, making galaxies appear to fly away from each other and leaving the expanding vacuums behind.

Connecting to Modern Data (Cosmological Coupling & DESI)

I realized this line of thinking heavily intersects with the recent Cosmologically-Coupled Black Hole (CCBH) models. Data from the Dark Energy Spectroscopic Instrument (DESI) suggests that dark energy is not a static Cosmological Constant, but actually changes and evolves over cosmic time. CCBH models propose that black holes grow in lockstep with the expansion of the universe because they enclose vacuum energy.

My model takes this a step further: What if this coupling is a two-way street? If black holes are intrinsically tied to vacuum energy and space-time metrics, a massive, uniform distribution of black holes at the horizon could theoretically act as the physical engine driving the time-evolving expansion history that DESI is currently mapping.

Addressing Potential Anomalies:

1. The Signal Masking Problem: A common critique is that we don't detect a distinct, local pull inside our solar system. My thought is that local massive bodies—like Jupiter—exert a dominant gravitational presence that dynamically blurs or masks our ability to isolate this microscopic background pull on nearby planets.

2. Kuiper Belt Drift: To find a clean signal, we would have to look past Jupiter to the outer ring of the solar system (the Kuiper Belt). If an external network of black holes is pulling at the universe, we might look for subtle orbital anomalies or drift among the distinct masses out there where local planetary gravity fades.

Questions for Discussion:

While gravity drops off via the inverse-square law, could a uniform, spherically symmetric distribution of horizon-scale black holes generate a net negative pressure that mimics a dynamic dark energy equation of state?

How would we model a space-time metric where the primary expansion force is a collective external gravitational gradient rather than intrinsic space-time stretching?

I'd love to hear your thoughts on the physics of this, where the math might break down, or how it might inspire alternative ways to look at cosmic expansion!
