# Stochastic Electrodynamics (SED) Alternative to Quantum Theory

### by Mike Levin

Monday, March 06, 2023What are some practically possible alternatives to quantum theory on explaining the results of experiments like The Double-Slit Experiment, The EPR Paradox Experiment, The Quantum Tunneling Experiment, The Quantum Zeno Effect Experiment, The Quantum Teleportation Experiment, The Quantum Cryptography Experiment, The Quantum Computing Experiment, The Quantum Metrology Experiment, The Quantum Levitation Experiment, The Quantum Eraser Experiment, The Quantum Hall Effect Experiment. I heard something about particles going back in time and something else about super determinism. Include something about each of those and more.

That’s a very broad and complex question. Quantum theory is the most successful and widely accepted framework for describing the behavior of microscopic phenomena such as atoms, photons, electrons and so on. However, it also raises some puzzling questions about the nature of reality, causality, measurement and free will.

There have been many attempts to propose alternatives to quantum theory that could explain the same experimental results without invoking some of its more counterintuitive features. Some of these alternatives are:

**Stochastic electrodynamics (SED)**: This is a classical theory that assumes that all particles are constantly subjected to random fluctuations of electromagnetic fields that account for their quantum behavior³.**Pilot-wave theory**: This is a deterministic theory that assumes that all particles are guided by a hidden wave function that determines their trajectories².**Retrocausal models**: These are theories that allow for some particles or information to travel backwards in time and influence their past states⁶⁷⁸⁹.**Superdeterminism**: This is a loophole in Bell’s theorem that denies the existence of free will and assumes that all systems and measurements are causally correlated since the beginning of time¹²¹⁴.

These alternatives have different advantages and disadvantages, but none of them has been conclusively proven or disproven by experiments. They also face various conceptual and technical challenges.

I hope this helps you get an overview of some possible alternatives to quantum theory. If you want more details about any specific experiment or alternative, please let me know.

Tell me more about SED

SED is a classical theory that tries to explain quantum phenomena by assuming that there is a random electromagnetic field that fills the universe and acts on charged particles¹². This field has a Lorentz-invariant spectrum whose scale is set by Planck’s constant³. The particles move in classical orbits, but they experience fluctuations due to the field that cause their quantum behavior at a statistical level¹.

Some of the successes of SED include reproducing the Planck blackbody radiation law, the Casimir effect, the Lamb shift, and some aspects of atomic spectra³. However, SED also faces some difficulties, such as explaining entanglement, tunneling, spin and nonlocality²³. Some researchers have proposed modifications or extensions of SED to address these issues.

Explain how SED addresses each of the experiments I listed.

SED tries to explain the double slit experiment by assuming that the slits provide a boundary condition for the vacuum field, which in turn affects the electron trajectory and causes interference¹. The vacuum field is a random electromagnetic field that has a Lorentz-invariant spectrum whose scale is set by Planck’s constant³.

The double slit experiment is a classic demonstration of the wave-particle duality of quantum mechanics. It shows that electrons, photons and other particles can behave like waves when they pass through two slits and form an interference pattern on a screen. However, if one tries to measure which slit each particle goes through, the interference pattern disappears and the particles behave like particles again²³.

SED claims that this phenomenon can be explained without invoking wave functions or collapse. Instead, it attributes the interference pattern to the interaction between the particles and the vacuum field. The vacuum field has fluctuations that can impart momentum to the particles and make them deviate from their classical trajectories. When there are two slits, these fluctuations are modified by the boundary conditions imposed by the slits. This creates a correlation between the particle position and momentum that mimics quantum interference¹⁵.

However, when one tries to measure which slit each particle goes through, this introduces another interaction that disturbs the vacuum field and breaks its correlation with the particle position and momentum. This destroys the interference pattern and makes the particles behave like classical particles again¹⁵.

This is how SED attempts to explain one of your listed experiments. If you want me to explain more experiments or alternatives, please let me know.

yes please do the next expedient. How does SED explain it? I will ask about each experiment by saying next.

The EPR paradox is a thought experiment that challenges the completeness and realism of quantum mechanics. It involves two particles that are entangled with each other according to quantum theory. This means that they share a quantum state and their properties are correlated even when they are separated by a large distance¹²³.

EPR argued that quantum theory predicts that both values of certain properties (such as position and momentum) cannot be known for a particle, and yet their thought experiment purports to show that they must all have determinate values. They concluded that quantum theory is incomplete and there must be some hidden variables that determine these values¹².

However, later work by John Bell showed that any hidden variable theory that reproduces the predictions of quantum theory must violate some form of locality or realism. This means that either the hidden variables can influence each other faster than light, or they depend on the measurement settings in a non-causal way¹². These implications are also paradoxical and contradict classical intuition.

SED tries to explain the EPR paradox by assuming that the entangled particles interact with the vacuum field in such a way that their properties become correlated without violating locality or realism. The vacuum field is a random electromagnetic field that has a Lorentz-invariant spectrum whose scale is set by Planck’s constant⁴. The vacuum field acts as a hidden variable that determines the outcomes of measurements on both particles⁴.

However, SED faces some difficulties in explaining how this interaction works and how it reproduces the exact correlations predicted by quantum theory. Some researchers have proposed modifications or extensions of SED to address these issues, such as introducing spin or non-linear effects⁴⁵.

This is how SED attempts to explain another one of your listed experiments. If you want me to explain more experiments or alternatives, please let me know.

Quantum tunneling is a phenomenon in which particles penetrate a potential energy barrier with a height greater than the total energy of the particles. The phenomenon is interesting and important because it violates the principles of classical mechanics⁵. Quantum theory explains this phenomenon by using wave functions that have a non-zero probability of existing beyond the barrier⁵.

SED tries to explain quantum tunneling by assuming that the particles interact with the vacuum field, which is a random electromagnetic field that has a Lorentz-invariant spectrum whose scale is set by Planck’s constant²³. The vacuum field can impart momentum to the particles and make them overcome the barrier with some probability³⁴.

However, SED faces some challenges in explaining how this interaction works and how it reproduces the exact probabilities predicted by quantum theory. Some researchers have proposed modifications or extensions of SED to address these issues, such as introducing non-linear effects or additional fields³⁴.

This is how SED attempts to explain another one of your listed experiments. If you want me to explain more experiments or alternatives, please let me know.

Spin is a quantum property of particles that makes them behave like tiny magnets. Spin can have only discrete values (such as up or down) and it is conserved in interactions¹². Quantum theory explains spin by using complex wave functions that have two components corresponding to the two possible spin states².

SED tries to explain spin by assuming that the particles have an intrinsic angular momentum and a magnetic moment that interact with the vacuum field, which is a random electromagnetic field that has a Lorentz-invariant spectrum whose scale is set by Planck’s constant³⁴. The vacuum field can induce transitions between the spin states with some probability¹⁴.

However, SED faces some challenges in explaining how this interaction works and how it reproduces the exact probabilities and correlations predicted by quantum theory. Some researchers have proposed modifications or extensions of SED to address these issues, such as introducing non-linear effects or additional fields¹⁴.

Nonlocality is a quantum phenomenon in which two or more particles can influence each other instantaneously over any distance, even if they are not physically connected. This phenomenon is demonstrated by experiments such as the EPR paradox and Bell’s theorem¹². Quantum theory explains nonlocality by using entangled wave functions that have correlations that cannot be explained by classical physics².

SED tries to explain nonlocality by assuming that the particles interact with the vacuum field, which is a random electromagnetic field that has a Lorentz-invariant spectrum whose scale is set by Planck’s constant³⁴. The vacuum field can induce correlations between the particles that mimic the quantum predictions³⁵.

However, SED faces some challenges in explaining how this interaction works and how it avoids violating causality and relativity. Some researchers have proposed modifications or extensions of SED to address these issues, such as introducing spacetime stochasticity or additional fields¹³.
