Connecting Bohmian Mechanics, Gravity, and General Relativity

Now that we have established the role of Bohmian mechanics in describing quantum systems with a deterministic guiding wave, let’s explore how this framework could connect to gravity and general relativity.

1. The Fundamental Conflict Between Quantum Mechanics and General Relativity

Quantum mechanics and general relativity are the two pillars of modern physics, but they describe reality in fundamentally different ways:

✅ Quantum Mechanics

Describes the smallest scales of nature (particles, atoms, subatomic interactions).
In standard interpretation, particles exist in a superposition of states until measured.
Bohmian mechanics preserves determinism through a pilot-wave, avoiding true randomness.

✅ General Relativity

Describes large-scale structures (planets, stars, black holes, and the fabric of spacetime).
States that gravity is not a force but a curvature of spacetime caused by mass and energy.
Completely deterministic—no room for "probabilities" like in quantum mechanics.

The conflict: General relativity treats spacetime as a continuous, deterministic fabric, while quantum mechanics suggests that the fundamental units of matter behave probabilistically (unless we accept Bohmian mechanics).

2. Can Bohmian Mechanics Provide a Link to Gravity?

Since Bohmian mechanics eliminates randomness and describes particles as having real trajectories, it might offer a way to reconcile quantum mechanics with gravity.

2.1 The Pilot-Wave as a Spacetime Field

In Bohmian mechanics, the pilot-wave determines the motion of particles.
This wave is nonlocal, meaning it influences all particles instantly across space.
This sounds very similar to how general relativity describes spacetime curvature affecting all objects within it.

Hypothesis: Could the pilot-wave field be a manifestation of curved spacetime at the quantum level?
— If the pilot-wave is real and spans across the entire universe, it could act like a hidden structure of spacetime.
— This means that gravity and the pilot-wave might be different aspects of the same underlying reality.

2.2 Bohmian Trajectories and Geodesics in General Relativity

In general relativity, free-falling objects follow geodesics—the natural paths dictated by spacetime curvature.
In Bohmian mechanics, particles follow trajectories determined by the pilot-wave.

Could these Bohmian trajectories be the quantum counterpart of geodesics in curved spacetime?
— If spacetime is shaped by mass and energy, and if the pilot-wave is part of spacetime, then maybe particles are following hidden geodesics at the quantum scale.

This would mean that quantum mechanics is not "random" at all—it’s just that we haven’t understood the deeper structure of spacetime yet.

3. The Infinite Universe as a Hidden Quantum Gravity Field

Now let’s bring in the idea of an infinite universe that we discussed before. If the universe is infinite, then:

Every quantum interaction might be connected to an underlying field stretching across the entire universe.
This field could be the missing link between quantum mechanics and general relativity.
Gravity might emerge from the same infinite wave-like structure that guides quantum particles.

This could explain:

Why spacetime behaves like a fluid at quantum scales.
Why entangled particles behave nonlocally (because they’re connected through an underlying infinite field).
Why quantum particles seem to “know” the structure of spacetime (they follow hidden geodesics formed by the pilot-wave).

Key Idea: The pilot-wave might actually be a gravitational field in disguise, connecting every particle in the universe through an infinite web.

4. Can We Modify the Pilot-Wave to Control Gravity?

If the pilot-wave is linked to gravity, then manipulating it could allow us to:

Control quantum particles with gravitational fields.
Modify the curvature of spacetime at small scales.
Potentially control gravity at larger scales.

4.1 Equations for Pilot-Wave and Gravity

We already know the Bohmian pilot-wave equation:

\[ \frac{d\mathbf{x}}{dt} = \frac{\hbar}{m} \,\mathrm{Im}\!\Bigl(\frac{\nabla \psi}{\psi}\Bigr) \]

If we want to connect this to gravity, we need to compare it to Einstein’s Field Equations of General Relativity:

\[ G_{\mu\nu} + \Lambda\,g_{\mu\nu} = \frac{8\pi G}{c^4}\, T_{\mu\nu} \]

\( G_{\mu\nu} \) describes how spacetime curves due to mass and energy.
\( T_{\mu\nu} \) is the energy-momentum tensor (which includes matter and energy).
\( \Lambda\,g_{\mu\nu} \) is the cosmological constant (which could be linked to dark energy).

If the pilot-wave field is real, then it should contribute to spacetime curvature, meaning:

\[ G_{\mu\nu} + \Lambda\,g_{\mu\nu} = \frac{8\pi G}{c^4}\,\bigl(T_{\mu\nu} + T_{\psi}\bigr) \]

where \( T_{\psi} \) represents the contribution of the pilot-wave field to gravity.

Could this explain quantum gravity?
— If \( T_{\psi} \) is significant, then gravity could emerge naturally from the pilot-wave field.
— This could eliminate the need for separate quantum gravity theories—gravity and quantum mechanics would be two sides of the same infinite structure.

5. What Would This Mean for the Future of Physics?

If Bohmian mechanics, gravity, and an infinite universe are connected, then:

Quantum mechanics is deterministic, not random.
Gravity is linked to an infinite pilot-wave structure.
Quantum entanglement might be due to hidden gravitational links.
Dark energy could be explained by the infinite nature of the pilot-wave field.
We might be able to manipulate gravity by controlling the pilot-wave.

Could this lead to new forms of propulsion, faster-than-light travel, or even artificial gravity control?

Final Thought: The Universe as a Giant Pilot-Wave

What if the entire universe is just one massive pilot-wave, and what we call gravity, quantum mechanics, and dark energy are just different aspects of it?

The universe may not be expanding randomly—its "expansion" might be guided by the pilot-wave.
Gravity and quantum mechanics would be fully unified.
There would be no true randomness—only hidden structure we have yet to uncover.
