INTRODUCTION
I first published the main
idea of this work on 23 October 2000 in my first article, entitled “Proof of
(c+v) (c−v) – The Speed of Light Is Relative.” Since I believed that this
work offered a direct proof of the existence of Alice Law, I included different
versions of the article in all Alice Law programs.

Over time, I considered
presenting the same subject inside a tube isolated from external conditions. In
April 2010, I published an article entitled “The Tube and the Golden Rule of
Special Relativity.” In August 2025, I updated this article under the title “The Tube
and the Theoretical Proof of Alice Law.”

Naturally, I also needed to
include this work in Alice Law Version 9. Here, I improved the animations and
tried to make the explanation as complete as possible.
HOW THE PROOF IS
STRUCTURED

The proof of the existence
of Alice Law consists of two stages.

In the first stage, the
problem to be solved is defined, and the Existing Theories of physics are asked
to solve it. “Existing Theories” includes Classical Mechanics, Electromagnetic
Theory, and the Special Theory of Relativity.

Before proceeding to the
second stage, the following conclusion is expected on behalf of the “Existing
Theories”:

“The problem could not be
solved using our current body of knowledge.”

At this point, Alice Law
enters the picture and solves the problem by presenting its own approach. The
existence of only one option for solving the problem proves the existence of
Alice Law.

Nor can it be argued that
the problem has no solution, because it is clear that a solution must exist.

INTRODUCING THE TUBE
APPARATUS

The tube is an apparatus
designed according to the principle of symmetry.

Inside the tube are two
slides that can move in opposite directions. There is a light source at each
end of the tube. The apparatus operates by sending a beam of light toward the
slides from each side while the slides are moving.

Relative to the axis of
symmetry marking the midpoint of the tube, the slides are always at equal
distances and occupy positions that are mirror images of one another. Their
speeds are equal in magnitude.

Light sensors are placed at
the edges and midpoint of each slide. Measurements are made using these
sensors. The edge sensors are partially transparent, allowing light to pass
through them and continue on its way. The middle sensors are opaque and serve
as the final destinations of the light.

An adjustable trigger
mechanism allows the light sources to be activated at the desired moment. When
the triangular projections at the centers of the slides align with the
triangles of the trigger mechanism, the light sources are triggered, and a beam
of light is emitted from each end of the tube. This study assumes that there is
no time delay between triggering and light emission. We also assume that the
emitted beams are directed entirely at the slides and propagate in a regular
rectangular shape.

Each slide has three
indicator lamps that provide information about the event: left, middle, and
right. If the light reaches the left and right edge sensors of a slide simultaneously,
the edge lamps turn green; otherwise, they turn red. The same applies to the
middle sensor. If the light from both directions reaches the middle sensor
simultaneously, the middle lamp turns green; otherwise, it turns red.

Each slide has two clocks.
Each clock shows how long the light arriving from its respective side takes to
travel the distance between the edge sensor and the middle sensor.

The upper part of the table
at the bottom left of the page displays the light speeds measured by the slide.
The lower part of the table
displays the arrival times of the light at the edge and middle sensors, as well
as the distance of the slide from the axis of symmetry. According to the
principle of symmetry, an event occurring on one slide also occurs simultaneously
on the other. Therefore, the measurements in the table apply to both slides.

All data in the animation
are defined relative to the reference frame of the tube.
ANIMATION CONTROLS

The lengths of the tube and
the slides can be changed using the controls on the right.

The color and transparency
of the light can be adjusted.

In the animation, the
slides are programmed to move at a speed of 1 px/frame.
The speed of light can be set between 1 and 10 px/frame.

Therefore, when
interpreting the animation, the speed of the slides should be understood as a
relative value:

Slide speed = c /
selected light-speed value

After configuring the
animation as desired, press the “Start” button to play it automatically. You
can also operate the animation manually using the control slider.

The animation has two
operating modes: “Existing Theories” and “Alice Law.” The behavior of the light
changes according to the selected mode.
DEFINITION OF THE PROBLEM

Problem statement: Using the apparatus, arrange for
the light emitted from both ends of the tube to reach the middle sensors of the
slides simultaneously.

Prerequisite

Although the problem may
appear simple, it has an inherent prerequisite. Imagine placing a lamp at each
edge of a slide. If we switch these lamps on simultaneously while the slide is
moving, their light reaches the sensor at the middle of the slide
simultaneously. (The Galilean Principle of Relativity is commonly used to
explain this situation.)

Therefore, solving the
problem requires the following condition: the light must first reach the left
and right edge sensors of the slides simultaneously. Only when this condition
is satisfied will the light reach the middle sensor of each slide
simultaneously.

Revised problem
statement:
Using the knowledge provided by the Existing Theories, demonstrate a solution
that allows the light emitted by the tube’s lamps to reach the edge sensors of
the slides simultaneously and then reach their middle sensors simultaneously.
THE PROBLEM IS NOT
INSOLUBLE

It cannot be claimed that
the problem has no solution. Consider using a single slide and the sensor at
its midpoint. There must be a situation in which the light from both directions
meets at the middle sensor. Since the apparatus operates in a way that
preserves symmetry, the same situation will also apply to the other slide.

The edge sensors form the
lock of the problem. The prerequisite that the light reach the edge sensors
simultaneously ensures that the problem is properly formulated. Since this
condition is upheld by the Galilean Principle of Relativity, it should not be
rejected.

We could also construct the
same problem by replacing each edge sensor with a pair of mirrors inclined at
45 degrees. In that case, the sequence would be as follows: incoming light
reflects off the first mirror, then immediately off the second mirror, and
travels toward the middle sensor. If the light from the two sides does not
reach the mirrors simultaneously, it cannot reach the middle sensor
simultaneously.

Without the edge sensors,
the problem produces a result detached from reality.
WHY THE EXISTING THEORIES
CANNOT PROVIDE A SOLUTION

For the Existing
Theories—including special relativity (SR)—the situation is as follows: from
the moment of emission, the light travels toward the slides at speed c.

Its arrival at the slides
occurs as follows:
- Suppose the light reaches the edge sensors
simultaneously. In that case, it cannot reach the middle sensors
simultaneously (“Demo 1” button).
- Suppose the light reaches the middle
sensors simultaneously. In that case, it will not have reached the edge
sensors simultaneously (“Demo 2” button).
Furthermore, because of the
principle of symmetry, the solution must be achieved simultaneously for both
slides.

There is no solution when
SR is used either.

You may think that SR can
provide a solution. Try it. The animation has been programmed using the tube’s
reference frame. Using the data in the animation, or by creating a similar
animation, you can program the events according to SR. It would not be
appropriate for me to write here how the events would unfold according to SR.
You can access the source code of this work here.

Ultimately, the Existing
Theories cannot open the lock and cannot provide any solution.

The solution lies beyond
the knowledge of the Existing Theories.

At this stage, we can now
say: The theory that provides the solution will be the correct theory.
ALICE LAW SOLVES THE
PROBLEM

Since the Existing Theories
cannot provide a solution, we can now think more freely. We are free to move
beyond the limitations of the Existing Theories.

To find a solution, let us
first consider the reference frame of a single slide. Let us assume from the
outset that the light approaching the slide has speed c in the slide’s
reference frame. Let us emit light simultaneously from the left and right, at
equal distances from the midpoint of the slide. The light approaching from both
directions will then remain at equal distances from the midpoint at every
moment. Consequently, it will reach the edge sensors simultaneously and then
reach the middle sensor simultaneously. Furthermore, neither the length of the
slide nor the length of the tube will change the result. In this situation, it
is also clear that the slide will always measure the speed of the incoming
light as c.

Now let us consider two
slides. To obtain a solution, the light must be emitted from equal distances
from the center of each slide. There is only one position that can provide the
solution: the light must be triggered when the midpoints of the slides are on the
axis of symmetry.

So far, so good. But the
light must reach both slides, moving in opposite directions, simultaneously. If
we keep the light as a single undivided beam, this cannot happen. This is where
we introduce the revolutionary idea and say:

Light travels at
speed c relative to the reference frame of its destination.

As a consequence of this
idea, we accept that the light emerging from the tube must separate. We can
explain this as follows:
The light emerging from the
tube initially forms a beam of photons. The destination of each photon in the
beam will be one of the two slides. Therefore, photons traveling toward the
same slide will form a group. The result will manifest itself as a separation
of the light. Each group of photons will take its own destination as its
reference and travel toward it at speed c.

Let me tell you something
interesting. The statement “Light travels at speed c relative to the reference
frame of its destination” is not actually unique to Alice Law. When it is said
that “The speed of light is c in all reference frames,” this naturally includes
the statement made by Alice Law. What is wrong is to think that the speed of
light is c in all reference frames. The solution offered by Alice Law shows
that the light-speed constant c is a constant defined relative to the
destination. This new knowledge is what solves the problem.

If we define the velocities
of the slides as +v and −v, then, in the tube’s reference frame, the light sent
from the left toward the lower slide moving to the right at velocity +v has
speed (c+v), while the light sent from the right has speed (c−v). In Alice Law,
this mathematics is called “(c+v) (c−v) Mathematics,” now known as “Alice
Mathematics.”

Alice Law is the only
option capable of solving the problem. Therefore, we can say that this solution
constitutes a proof of the existence of Alice Law.
