One of the biggest mysteries in astrophysics is the missing mass problem—why galaxies and the universe don’t behave as they should based on the observable matter. Dark matter has been the prevailing theory, a mysterious form of matter that interacts gravitationally but not with light, making it invisible. But what if quantum entanglement and unmeasurable quantum states are both part of the equation?

Let’s explore a speculative idea: that entangled particles, perhaps hidden in black holes or other unreachable areas of the universe, could be contributing to the gravitational effects attributed to dark matter. While this idea is still speculative, it offers an intriguing twist to the ongoing discussion about what could explain the universe’s hidden mass.

Also, from our philosophical viewpoint, this allows us to dabble in the irrational a bit with as-of-yet-disproven empirical ideas.

The Core Idea: Hidden Quantum Entanglement

Quantum entanglement describes a phenomenon where two particles become linked, such that the state of one particle immediately affects the other, regardless of distance. Imagine one particle falling into a black hole or some unreachable region. Would its quantum connection with a partner particle break? And if not, could these hidden entangled states have an effect on the universe?

One speculative possibility is that quantum entanglement could contribute to gravitational effects. When one part of an entangled pair becomes unobservable (like being trapped in a black hole), it might still influence the overall gravitational pull in the universe. This idea would suggest that some of the “missing mass” could actually be information and matter we cannot currently measure.

While this theory is far from proven, it hints at a deeper layer of complexity in the universe’s structure, potentially coexisting alongside dark matter.

What We Know: Dark Matter and Entanglement

Dark matter is still the leading explanation for the missing mass. Observations of galaxy rotation curves, gravitational lensing, and the large-scale structure of the universe all support the existence of an unseen form of matter. Yet, quantum entanglement’s role in large-scale phenomena has been studied in relation to dark matter. For example, research into dark matter halos suggests that parts of galaxies could be entangled, affecting how mass and gravity  gravity are distributed.

Additionally, ideas like extra dimensions could play a role. Some theories propose that particles like gravitons could leak into hidden dimensions, diluting gravitational effects and contributing to the same dark matter-like phenomena.

Speculation and the Limits of Knowledge

While both dark matter and quantum entanglement are speculative when applied to cosmic structures, they both raise important questions. Could the universe’s missing mass be a combination of these factors? Perhaps dark matter remains the stronger theory, but entanglement and hidden quantum states might contribute to the larger picture.

Of course, it’s also possible that reality is something entirely different—that both dark matter and quantum entanglement only scratch the surface of our understanding. As science progresses, new theories will emerge, potentially redefining our view of the cosmos.

Conclusion: Two Theories, One Big Mystery

The relationship between quantum mechanics, gravity, and the missing mass of the universe remains one of the greatest puzzles in science. Dark matter is still the most likely solution, but exploring alternative ideas, like hidden quantum entanglement, expands the conversation. Both ideas remain speculative, and reality may surprise us with something entirely unexpected.
