After the Light: 8 Minutes 20 Seconds to Interstellar Diffusion— Part 4
After the Light
Layers of what has not yet arrived, and the slow escape of matter—from fusion to interstellar diffusion.
After the Light
The light
has already passed.
It paused
briefly
on the surface,
then left
as if nothing
had happened.
Wavelengths
once held,
then released,
surfaces
that trembled
for a moment
then vanished,
things
that dispersed outward
almost imperceptibly.
We
recorded
even that scene.
But
what disappeared
was not
the light.
The record
simply
did not reach
beyond that point.
Beneath the surface
there remains
a layer
not yet observed.
A velocity
sound cannot reach,
a change
sensation cannot follow,
time
that appears not to flow
yet in truth
is maintained
too evenly
to be noticed.
There
nothing
collapses.
Only
changes
a little
later.
What we once
called diffusion,
processes
we believed were disappearance,
paths
we assumed were endings.
All of them
perhaps
did not vanish completely
but were maintained
at another speed.
So now
the record
leaves the landscape.
From the scene
left by light
into the time
through which light passed.
From surface
to interior.
From sensation
to structure.
Toward the layer
where things
not yet fully dispersed
remain.
From here
it is no longer
the visible world
but the maintained one.
Things flowing beyond radiation pressure
From nuclear fusion
to interstellar diffusion.
A scene
where all matter
slowly escapes
into space.
1 — 07:11 — Surface and photon
A gamma photon
generated at 15 million K
in the solar core
reaches the ocean surface
after hundreds of thousands of years
of random scattering.
From fusion
to sea level —
a gamma photon
passes 10⁵ years
of random scattering
then arrives at Earth
in 8 minutes 20 seconds.
Before the star rises
the energy
has already arrived.
Photons
do not travel
in straight lines.
Solar core temperature
approximately 15 million K.
Hydrogen fusion.
While two protons
bind into helium,
one gamma photon
is generated.
For that photon
to escape
the interior of the Sun
takes on average
hundreds of thousands of years.
Because of plasma density
it cannot move straight.
Absorption.
Re-emission.
Scattering.
Re-absorption.
For hundreds of thousands of years
it passes
a random path
then leaves
the surface.
From that moment
8 minutes 20 seconds.
Speed of light
299,792 km/s.
A velocity
the human nervous system
can never
directly feel.
That light
touches
the ocean surface
now.
2 — Quantum rearrangement at the water surface
Thousands of wavelengths
380–700 nm
collide simultaneously —
the moment
electrons on the water surface
rearrange
through discontinuous quantum jumps.
380 nm to 700 nm
visible light.
Beyond it
ultraviolet.
Infrared.
Microwave.
Thousands of wavelengths
arrive simultaneously.
Each wavelength
a different energy.
Blue
short and strong.
Red
long and deep.
Electrons
on the water surface
respond
to each wavelength
with different vibrations.
When one electron
absorbs one photon
its orbital energy
changes.
Quantum jump.
But this jump
is not continuous.
Between 0 and 1
no intermediate.
It moves
instantaneously
to another energy level.
That
is quantum mechanics.
The moment light arrives
electrons on the water surface
rearrange
discontinuously.
On a continuous world
trillions
of discontinuous events
occur simultaneously.
3 — Velocity field of rotation, revolution, and galactic orbit
A velocity field
where rotation, revolution,
and galactic orbit overlap —
water molecules
that appear still
are moving
hundreds of km per second.
Planetary velocity field.
Earth rotation
approximately 465 m/s
at the equator.
Earth orbital velocity
approximately 29.78 km/s.
Solar system
galactic orbital velocity
approximately 220 km/s.
These three velocities
operate simultaneously.
At this moment
a single water molecule
on the ocean surface
moves
with the vector sum
of all three.
Yet sensory organs
cannot detect
this speed.
Because everything
moves
at the same velocity.
Relative velocity
zero.
So it feels
stationary.
In reality
it is piercing
through space
at hundreds
of km per second.
4 — Probabilistic evaporation
Hydrogen bonds
20 kJ/mol
break —
probabilistic evaporation
where only a few molecules
leave the liquid surface.
Beginning of evaporation.
A single molecule
on the surface.
Temperature rises.
Energy absorbed.
To shift
from liquid
to gas
hydrogen bonds
must break.
H₂O intermolecular bond energy
approximately 20 kJ/mol.
Only a tiny fraction
with sufficient energy
leave the surface.
Departure velocity
hundreds of m/s.
Most
fall back.
Gravity.
But within
the Maxwell-Boltzmann distribution
a very small tail.
A few molecules
approach escape energy.
Earth escape velocity
11.2 km/s.
Most
never reach it.
But with collisions
and reheating
repeated
some
probabilistically
do.
Not explosive.
Thousands of years.
Tens of thousands.
Hundreds of millions.
Very slowly
Earth’s atmosphere
leaks
into space.
This
is atmospheric escape.
5 — Open system: the human surface
Most
do not reach
11.2 km/s.
A few
do.
Over hundreds of millions of years
the atmosphere
leaks
into space.
Human surface.
Same moment.
Another surface.
Skin
1 cm².
Tens of billions
of molecules
released
per second.
Moisture.
Lipids.
Microscopic organics.
The human body
is not
a solid.
Thermodynamically
an open system.
Constantly
losing matter.
Gaining matter.
Over 100 years
most atoms
once composing the body
have already
been replaced.
An individual
is not fixed matter
but a maintained pattern.
As long as the pattern
is maintained
existence
is maintained.
6 — Exosphere: the boundary of collision
From skin
1 cm²
tens of billions
of molecules exchange
each second —
the point
where the human
is revealed
not as fixed matter
but a maintained pattern.
Atmospheric boundary
approximately 100 km.
Above this
collision frequency
drops sharply.
Exosphere.
A molecule
can travel
kilometers
without collision.
Here
the fastest molecules
move farther
and farther.
They slowly
escape
the gravitational well.
A single escaped molecule
enters
interstellar space.
No air.
No friction.
No sound.
Velocity
almost indefinitely
maintained.
Millions of years.
Hundreds of millions.
If direction
is preserved
it continues.
7 — Interstellar diffusion
Exosphere
around 100 km —
the boundary
where molecules
travel kilometers
without collision
and slowly escape
gravity.
Interstellar diffusion.
Density
less than one atom
per cm³.
Almost vacuum.
But not absolute.
Hydrogen.
Helium.
Dust.
Ions.
Escaped molecules
enter
this sparse medium.
There
rare collisions.
Each collision
alters trajectory.
Exchanges energy.
After millions
of collisions
position
entirely different.
We call this
diffusion.
But its scale
exceeds
human imagination.
Hundreds of millions of years.
Tens of billions of km.
Interstellar distances.
8 — Delayed observation
Less than one atom
per cm³ —
interstellar space
where escaped molecules
after hundreds of millions of years
arrive
somewhere else.
Delayed observation.
A telescope
receives light.
But when that light
departed
Earth had no humans.
400 million years ago.
500 million.
The planet we see
is not the present planet.
It may already
be gone.
It may have already
lost its ocean.
Light
always delivers
the past.
The universe
never shows
the present directly.
Only
delayed states.
9 — After 2100: nearly closed
Light delayed
hundreds of millions of years —
a structure
where what we see
may already be gone.
After 2100
some beings
halt
this natural diffusion.
No molecular loss.
No entropy increase.
Rearrangement
instant.
Open system
→ nearly closed system.
Matter
no longer leaks outward.
So the question
changes.
Will we
return
to natural diffusion.
Or
maintain cohesion
forever.
10 — The layer that has not yet arrived
From open system
to nearly closed —
the final choice:
disperse naturally
or remain condensed.
Earth
still rotates.
The atmosphere
still slowly
leaks into space.
All existence
is dispersing
at an extremely slow rate.
Only one difference.
Will it disperse
naturally.
Or
by choice.
The universe
does not distinguish
between the two.
It receives
all particles
equally.
So
we receive
the next scene
not now
but delayed.
We are not
seeing
what is happening now.
We are receiving
what has already passed
late.
So
the next record
begins
not in the present
but
in a layer
that has not yet
arrived.
