Start Small: Making the Communication Question Testable

September 11, 2026

Once Project Communication became a separate research path within Beyond the Light Barrier, another problem became apparent.

The question was still much too large.

Asking whether humans could someday communicate faster than light across interstellar distances may be interesting, but it does not immediately give us an experiment we can perform.

We needed to make the question smaller.

Much smaller.

From Light-Years to the Laboratory

The original motivation for Project Communication involves enormous distances.

If future spacecraft could someday travel effectively faster than light, conventional communication delays could become a significant limitation. Ultimately, we would want communication capable of operating across astronomical distances.

But that is an objective, not a starting experiment.

Suppose some physical mechanism really could transmit information in a way that differs from ordinary electromagnetic propagation.

The first question should not be whether it works across ten light-years.

It should be:

Can we detect the effect across ten centimeters?

Perhaps the appropriate distance would actually be one centimeter, one meter, or ten meters. The precise number depends upon the physical mechanism being tested and the measurement resolution available.

The principle is what matters:

Find the smallest scale at which the hypothesis makes a measurable prediction.

Why Smaller Is Better

Small experiments provide several advantages.

Distances can be measured accurately.

Timing can be controlled more precisely.

Environmental conditions can be monitored.

Equipment can be physically isolated.

Experiments can be repeated many times.

Potential sources of interference can be investigated.

And, perhaps most importantly, other researchers could reproduce the experiment without requiring spacecraft or enormous budgets.

If a proposed effect cannot survive controlled laboratory testing, there is little reason to design an interplanetary version of the same experiment.

What Are We Actually Looking For?

This question requires considerable care.

Project Communication is not simply looking for something unusual.

An unexpected measurement is not automatically evidence of new physics.

Laboratories encounter unexpected results all the time because of equipment behavior, electromagnetic interference, thermal effects, timing errors, software bugs, statistical fluctuations, calibration problems, environmental coupling, or assumptions that turned out to be wrong.

Therefore, an experiment needs to begin with a prediction.

A simplified example might look like this:

A transmitter encodes a randomly generated sequence of bits.

A conventional communication channel is prevented from carrying that sequence to a physically separated receiver during the measurement interval.

The proposed mechanism predicts that information should nevertheless become detectable at the receiver.

The receiver records its result independently.

Only afterward are the transmitted and received records compared.

If the receiver cannot recover information beyond what chance and known physical coupling predict, the experiment has not demonstrated communication.

If an apparent correlation occurs, the appropriate response is not immediately:

We discovered faster-than-light communication.

The appropriate response is:

What conventional explanation did we miss?

Information Is the Critical Test

This distinction is particularly important when considering quantum phenomena.

Two systems can display correlations without providing a controllable communication channel.

For Project Communication, correlation alone is insufficient.

The sender must be able to choose or encode information, and the receiver must be able to recover that information in a manner that cannot be explained by a conventional signal path or prior shared information.

That gives us a much stronger experimental target:

controlled information transfer rather than unexplained correlation.

Timing Matters

Eventually, a claim of faster-than-light communication would require more than demonstrating an unusual information channel.

We would also need to determine how quickly information traveled.

At very short distances, that creates a serious measurement problem.

Light crosses one meter in only a few nanoseconds.

If an experimental system introduces microseconds or milliseconds of electronic processing delay, simply comparing the time at which two computers report events would tell us very little about the propagation mechanism itself.

This means the first experiment does not necessarily need to prove faster-than-light propagation.

There may be two separate questions:

First: Does an unconventional communication channel exist at all?

Second: If it exists, what is its propagation behavior?

Separating those questions may make the research considerably more manageable.

Distance Becomes an Experimental Variable

If an effect were ever reproducibly demonstrated, distance itself could become part of the experiment.

For example:

1 centimeter.

10 centimeters.

1 meter.

10 meters.

100 meters.

Greater distances only when justified by previous results.

The important measurement would not merely be whether the effect continues to exist.

We would examine how it changes with distance.

Does signal strength decline?

Does error rate increase?

Does propagation time increase?

Does the effect disappear beyond some distance?

Does it behave exactly as a conventional physical interaction should?

Each outcome provides information.

Null Results Matter

Suppose we construct an experiment around a particular Project Communication hypothesis and detect nothing.

That does not necessarily mean the experiment failed.

If the apparatus was capable of detecting the effect predicted by the model, then the absence of that effect constrains the model.

The result might tell us:

This mechanism does not operate under these conditions at or above this sensitivity.

That becomes part of the permanent research record.

The model may need modification.

It may need a different experiment.

Or it may need to be retired.

The important point is that we should not continually change a hypothesis merely to prevent it from being falsified.

The Experimental Ladder

A useful picture is beginning to emerge for Project Communication.

Rather than one enormous experiment, the project can be thought of as an experimental ladder.

Stage 1 — Mathematical viability

Does the proposed mechanism survive basic theoretical analysis?

Stage 2 — Detectability

Does the model predict something that available instruments could actually measure?

Stage 3 — Laboratory experiment

Can the predicted effect be produced under controlled conditions?

Stage 4 — Independent reproduction

Can another experiment reproduce the result?

Stage 5 — Conventional-explanation challenge

Can known signal paths, environmental coupling, equipment behavior, statistics, or ordinary physics explain the result?

Stage 6 — Distance scaling

Does the effect behave predictably as separation increases?

Stage 7 — Propagation measurement

Can its speed or other propagation properties be measured?

Only after surviving those stages would increasingly large terrestrial or space-based experiments make sense.

Engineering Must Wait for Physics

As an engineer, I naturally find myself thinking ahead.

How would the transmitter work?

How would the receiver work?

How would the devices synchronize?

How much energy would they require?

How could one eventually operate aboard a spacecraft?

Those are useful questions because they can expose weaknesses in an idea.

But there is also a danger.

It is possible to design an elaborate engineering system around a physical effect that has never been demonstrated.

For now, Project Communication needs to keep a clear distinction between two activities:

Physics asks whether the effect exists.

Engineering asks how to use it if it does.

We can think about both, but we must not confuse an engineering concept with evidence that the underlying physics works.

A Different Kind of Progress

This approach changes what progress means for Beyond the Light Barrier.

Progress does not necessarily mean getting closer to building an interstellar communication device.

Progress may mean eliminating a mechanism that does not work.

It may mean discovering that a predicted effect is far below measurable levels.

It may mean identifying an assumption that contradicts established physics.

It may mean reducing a complicated question to one experiment capable of giving us a meaningful answer.

That is still progress.

Where Project Communication Goes Next

The next challenge is therefore not to design the final communication system.

It is to continue narrowing the candidate mechanisms until we can identify one with:

a clearly stated physical hypothesis,

a quantitative prediction,

a measurable effect,

a practical experimental configuration,

appropriate controls,

and a result capable of falsifying the hypothesis.

When Project Communication reaches that point, something important will have happened.

We will have moved from asking whether extraordinary communication might someday be possible to asking nature a specific question that an experiment can answer.

That is the direction the research now needs to take.

Why Communication Comes First

September 11, 2026

One of the earliest questions in Beyond the Light Barrier was about faster-than-light travel.

But that question quickly led to another one:

If we could someday travel across enormous distances much faster than we can today, how would we communicate across those same distances?

That question has become important enough to create a separate research path within the project.

The Communication Problem

Imagine, purely as a thought experiment, that a spacecraft could someday reach a destination several light-years from Earth in substantially less time than light would take to cross the same distance.

The spacecraft might arrive quickly, but a conventional radio transmission back to Earth would still propagate at approximately the speed of light.

That creates an unusual situation.

Transportation might have become fast while communication remained slow.

For nearby missions, communication delays measured in seconds or minutes are manageable. Across interstellar distances, however, the delay would be measured in years.

This does not make faster transportation useless, but it could greatly complicate navigation, mission control, emergency response, scientific coordination, and communication between distant human communities.

That led to an important decision:

Do not treat communication as something to solve after propulsion. Investigate it independently and, where possible, earlier.

A Separate Research Program

This became the foundation of Project Communication.

The original investigation began with wormholes because general relativity contains mathematical solutions associated with wormhole geometries, and traversable wormholes have been studied theoretically in the scientific literature.

That statement requires an important qualification.

The existence of mathematical wormhole solutions does not demonstrate that usable traversable wormholes exist in nature or can be engineered.

No engineered traversable wormhole capable of transmitting information has been experimentally demonstrated.

Furthermore, many theoretical traversable-wormhole models introduce severe requirements or unresolved problems, including exotic stress-energy conditions, stability, quantum effects, and causality.

For that reason, the project's communication research should not become a search for evidence supporting wormholes.

The broader question is:

Is there any physically permissible mechanism that could someday allow information to cross very large distances substantially faster than today's communication methods permit?

Wormholes are one hypothesis worth investigating.

They are not the required answer.

Quantum Entanglement Is Not Currently an FTL Communication System

Quantum entanglement naturally enters this discussion.

Entangled systems can exhibit correlations that cannot be explained by ordinary classical models. These correlations have been demonstrated experimentally and are fundamental to modern quantum physics.

But this does not currently provide a method for controllably transmitting information faster than light.

Standard quantum mechanics obeys what is commonly called the no-communication or no-signalling principle: measurements performed on one portion of an entangled system cannot, by themselves, be controlled to transmit usable information instantaneously to the distant observer.

Therefore, Beyond the Light Barrier will not describe quantum entanglement as an existing FTL communication technology.

It remains relevant because quantum information, spacetime geometry, and gravity intersect in important areas of theoretical physics. But any proposed communication mechanism must demonstrate something beyond ordinary entanglement correlations before it could qualify as a communication channel.

Start Small

Perhaps the most important decision in Project Communication has been about scale.

It would be tempting to begin by asking:

How could we communicate instantaneously with another star?

That is probably the wrong experimental question.

Instead, suppose some currently unknown or unexploited physical mechanism permits information to traverse spacetime differently from an ordinary electromagnetic signal.

Before attempting kilometers, planets, or light-years, we should ask whether the effect exists across the smallest distance at which it could be unambiguously measured.

The first meaningful experiment might therefore involve centimeters or meters rather than astronomical distances.

If nothing anomalous can be demonstrated at small scales under conditions where a proposed model predicts an effect, increasing the distance does not solve the underlying problem.

If an effect were reproducibly detected, the next question would become whether the distance could be increased while preserving it.

This suggests a progression:

detect → reproduce → eliminate conventional explanations → increase distance → test scaling → investigate engineering

Only much later would deep-space communication become appropriate.

The Carrier-Pigeon Problem

Another distinction has emerged during the research.

There may be an important difference between transmitting information through a hypothetical spacetime connection and transporting matter through one.

Our preferred research direction is information transmission.

If a hypothetical mechanism required particles or physical objects to pass between endpoints, the engineering problem could become substantially more difficult.

However, that possibility should not automatically be discarded.

If future analysis were to show that information alone cannot be transmitted but physical matter can traverse some viable connection, then matter could potentially act as an information carrier.

That would be more analogous to sending a message with a carrier pigeon: the information reaches its destination because something physical carrying the information travels there.

This is not our preferred solution.

It is an alternative branch to preserve in the research record in case the primary approach fails.

The Long-Term Experiment

If small-scale communication experiments ever produced a genuine, independently reproducible effect, the research could gradually move outward.

Laboratory distances could lead to terrestrial distances.

Terrestrial experiments could eventually lead to Earth-to-orbit or Earth-to-Moon tests.

Only after substantial evidence existed would a deep-space experiment become scientifically reasonable.

One long-term concept being preserved within the project involves a spacecraft eventually traveling far enough into the Solar System to establish a distant communication endpoint.

Voyager 1 provides a useful conceptual benchmark because humanity already has experience communicating with a spacecraft at extraordinary distances.

A future mission might someday travel to or beyond Voyager's distance while carrying both conventional communications equipment and whatever experimental communication system had survived the earlier research stages.

This is an engineering concept, not a proposed mission and not evidence that such communication technology exists.

Its value today is simply that it forces us to think about where successful laboratory research would eventually have to lead.

What Would Count as Evidence?

Project Communication needs a particularly high standard because claims involving faster-than-light or nonlocal communication would be extraordinary.

A successful experiment could not simply show two measurements that appear correlated.

It would need to demonstrate controlled information transfer.

The experiment would need defined transmit and receive events, synchronized timing, appropriate controls, statistical analysis, elimination of conventional electromagnetic or mechanical coupling, independent replication, and a clearly specified prediction made before the experiment.

Most importantly, the experiment must have a result that can prove the proposed mechanism wrong.

If every possible outcome can be interpreted as success, the experiment has not actually tested the hypothesis.

Where We Are Today

At this stage, Beyond the Light Barrier has not demonstrated faster-than-light communication.

We do not have evidence that an engineered traversable wormhole can transmit information.

We do not have evidence that quantum entanglement can be used to send controllable information faster than light.

And we do not yet have an experimentally validated alternative mechanism.

What we do have is a research question that has become considerably better defined:

Can any physically permissible mechanism produce controllable information transfer across distance in a way that exceeds conventional communication limits—and can we design the smallest practical experiment capable of falsifying that possibility?

That is the question Project Communication will continue pursuing.

Before trying to communicate across the stars, we first need to determine whether there is anything worth trying to scale beyond the laboratory.

That seems like the right place to begin.
