141: Chapter 141 The Dark Dust String Hypothesis

Jiang Lin was very clear that MPS-Agent α was not a general artificial intelligence in the true sense.

Its skeleton was a fault correlation model extracted by MPS-Diagnose from tens of thousands of failed tests.

Its flesh and blood were the computing power scheduling tables of MPS-Scheduler, the mechanical fatigue records of MPS-Forge, the hazard markings of the field map, the symbol conflict trees of the proof engineering module, and the experimental logs that Jiang Lin personally wrote down line by line over decades.

It had no self-awareness, nor did it have creativity independent of data.

It would not discover truth for Jiang Lin.

It could only, when Jiang Lin was about to make mistakes due to exhaustion, anxiety, inertial thinking, or subjective optimism, put those failure records he had long forgotten back onto the screen.

Of course, its value did not lie in replacing Jiang Lin's thinking.

As long as it could help him avoid taking even a single wrong step, it would be fine.

From the thirty-first year to the thirty-fourth year.

Over these four years, MPS-Agent α was like a miniature black hole continuously sucking in surrounding data, crazily growing and expanding from an initial archiving script solely used for matching fault codes, ultimately becoming Jiang Lin's indispensable cybernetic body.

Although it still did not speak.

Still refusing any form of anthropomorphic interaction.

It also had no personality and would not suddenly utter a goosebump-inducing greeting in the middle of the night.

What it relied on were tedious expert system rules, massively structured databases, high-dimensional vector space feature retrieval, topological graph structure algorithms, Bayesian probabilistic statistical models, Jiang Lin's day-to-day manual feature annotations, and that treasury of records accumulated through decades of loneliness and countless part destructions.

Under Jiang Lin's modular construction, it first developed a massive memory neural center.

Named: [MPS-Memory / Core Memory Base].

All data that had ever occurred at the Outpost was shattered and stored strictly classified according to system hierarchies.

Every proof draft iteration and obsolete version in the PFR direction.

The dynamic simulation logs of the G platform under various extreme terrain parameters.

The telemetry logs of G-Explorer delving deep into the Wasteland.

Tens of thousands of hexadecimal fault codes spewed out by PMCU-17 under electrical stimulation.

Massive matrices of multispectral aerial survey maps captured by drone swarms under different wavebands.

Three-dimensional point cloud settlement data of the Wasteland terrain.

And even the painful lessons of every experimental failure caused by incorrect parameter settings.

Every record written into the database was tagged with long metadata tags.

Source sensors, timestamps precise to the millisecond, the environmental temperature and humidity states at the time, data reliability weight percentages, and whether it possessed reproducibility on mathematical models.

Listening to it, this sounded merely like the job of a super hard drive, not grand in the slightest.

But this actually changed Jiang Lin's survival and work paradigm to a great extent.

In the past, he had to, like an ascetic, cram all technical details into his physical brain, relying on memory and the physical labor of flipping through notes to keep all grand projects running.

And now, when Jiang Lin sat before the screen, attempting to design a completely new polyurethane formula for foot shock absorbers, MPS-Memory would use component vector retrieval to quietly unearth a dust-covered record from the depths of the database in less than half a second.

That was during a certain cold winter seventeen years ago when Jiang Lin had used a similar formula, but during a minus-thirty-degree gravel collision experiment, a catastrophic interlayer glass transition delamination had occurred.

It would not decide for Jiang Lin whether or not to continue the experiment like a mentor.

But it would paste that fracture analysis report from seventeen years ago onto the right side of the screen, accompanied by a piece of advice.

[System Prompt: "In historical combinations with a chemical molecular weight ratio similarity of 82%, brittle delamination failure has occurred at extremely low temperatures."]

[Experimental Suggestion: "Should a high-strength low-temperature physical impact control validation group be immediately added to the current experimental matrix?"]

When Jiang Lin first saw this prompt spanning a seventeen-year river of time, he was very happy.

On this boundless Wasteland that buried the old civilization, he was finally no longer completely alone.

Although this was not companionship between humans.

MPS-Agent α would not comfort him, would not understand his loneliness, and would not respond to his emotions amidst the roar of the cooling pumps in the middle of the night.

It only silently remembered everything.

Remembering every fractured material, every failed route, every proof version that he had deleted and then picked back up again, and those details that seemed meaningless at the time but could suddenly save a life a dozen years later.

And when Jiang Lin realized this, he no longer treated MPS-Agent α merely as a risk validator for the Outpost.

Since it could remember engineering failures, why couldn't it remember proof failures?

Since it could find hidden correlations from mechanical fractures and thermodynamic anomalies, why couldn't it find the logical faults masked by human brain inertia from hundreds or thousands of pages of mathematical manuscripts?

Thus, after MPS-Memory gradually stabilized, Jiang Lin began connecting the next core module into the backbone architecture of Agent α.

That was a module specifically designed for theoretical Physics and mathematics.

[MPS-Proof / Formal Proof Engine]

It did not possess the wisdom to pioneer theories, but it was a strict referee that could generate complex lemma logical dependency graphs for Jiang Lin.

Conducting symbolic consistency scanning checks across hundreds or thousands of pages of manuscripts.

Establishing mandatory indexes for those extreme algebraic topological degradation scenarios that Jiang Lin attempted to ignore.

And even pre-judging possible reading obstacle points during paper reviews by calculating the depth of logical jumps.

It could not prove the PFR for Jiang Lin.

But it could keenly point out that a certain Greek symbol had been used with a completely different Physics definition in the third technical memorandum three years ago.

It could use a red box to remind Jiang Lin that a certain extreme degradation scenario involving a singularity state had only been hastily deduced with two lines of text on the edge of a scratchpad, lacking rigorous axiomatic support.

It could even use graph theory algorithms to highlight and print out in advance the reading paths where a scholar of Professor Han Yanshan's level was most likely to get stuck due to logical faults while reading.

Later on, it was the further deep evolution of MPS-Forge (Mechanical Forging System) under the Agent α architecture.

It governed the entire life cycle of the Outpost from the aging G-01, the meritorious G-Explorer-A, up to the currently most mature G-Explorer-B series.

By connecting to a matrix-style sensor array, it analyzed in real-time the end-effector failure probability of multi-legged mechanical platforms, the creep fatigue of polymer materials under ultraviolet light, the optimal phase strategy solutions in nonlinear dynamics, the thermal imaging of servo motor stator temperatures under high-load operation, and the drift over time of inertial navigation sensors, thereby automatically generating the next round of candidate hardware iteration experimental parameter combinations without manual intervention.

And in the distant seventh year, the field map module that had been hastily put together to prevent the first-generation platform from getting lost finally ushered in its nirvana during this period, being officially incorporated into the backbone network.

Jiang Lin gave it the final tactical name: [MPS-Field / Topographic Field Analysis Hub].

Its capabilities had undergone a qualitative leap.

It was able to feed visible light and infrared images from high-altitude drones, impedance data transmitted back by the physical contact between G-Explorer's feet and the ground, three-dimensional point clouds formed by terrain LiDAR, weathering settlement rates of abnormal geology, Jiang Lin's manual marker points over the years, and environmental evolution records caused by the microclimate changes of the Wasteland over more than a decade, all into a multi-dimensional tensor fusion model.

It could output in real time risk contour maps containing geological shear forces, navigation roadmap alternatives based on energy consumption minimization, probability predictions of underground facilities suspected to be buried by wind and sand, and expedition exploration priority rankings.

And as the core of the entire system scheduling, the Physics connotation of MPS-Scheduler had been rewritten by Jiang Lin.

In the past, scheduling only targeted silicon-based computing power inside the chip.

Now, the engineering philosophy Jiang Lin comprehended through dismantling PMCU-17 allowed scheduling to encompass the dimensions of the Physics world.

Thermodynamic impedance became a scheduling variable.

The superposition of minor hardware failure probabilities became a scheduling variable.

The withdrawal safety redundancies of fuel and structure became a scheduling variable.

All tasks had to comply with three major ironclad rules: Physics interruption at any time, lossless state migration, and complete logical rollback.

From the day the architecture was established, whether it was the high-load fluid mechanics computing tasks in the background, the field tests of the G-Explorer platform in the wind and sand, the regional cruising of high-altitude drones, the extremely dangerous heat flux diagnostic window targeting PMCU-17, or simple battery pack charge-discharge cycles, none of them were isolated behaviors anymore.

Within the same three-dimensional four-dimensional time-scheduling diagram, they mutually constrained and compromised with one another like a group of precision clocks.

The last piece of the puzzle to be completed was MPS-Checkpoint (Global Breakpoint Protection System).

It was the Outpost's ultimate life-saving talisman.

It was specially used for disaster-level state preservation of ultra-long-cycle tasks.

Whether it was the deduction versions of mathematical papers hundreds of pages long, the half-year low-pressure penetration testing environment for PMCU-17, the three-month Physics wear simulation of the G platform, the fusion of massive topographic point cloud matrices, or the training parameter weights of small machine learning models based on statistics.

Under the blessing of MPS-Checkpoint, all long-cycle grand tasks had to be able to, upon experiencing sudden power outages, equipment thermal runaway overloads caused by damaged cooling pumps, highest-level sandstorm invasions, loss of communication contacts during expeditions, or even under the most extreme hypothesis—Jiang Lin being forced to abandon this Outpost and relocate positions—re-import the state with acceptable data loss and continue deductions from the nearest trusted breakpoint.

At this point, the capability boundaries of MPS-Agent α were clearly demarcated by Jiang Lin using the language of engineering, engraved onto the root directory of the code.

The limit of what it could do: quickly organize high-dimensional data.

Discover hidden nonlinear Physics fault correlations in chaotic data.

Propose conservative experimental planning suggestions based on Bayesian historical probabilities.

Check out fatal logical symbol conflicts in massive texts.

Mark geographical environmental anomalies through multispectral data fusion.

Calculate global task survival priorities based on heat, electricity, and failure rates.

Forbidden zones it could not penetrate: generating any independent theoretical breakthroughs in basic science out of thin air.

Reverse Physics deciphering and understanding the underlying logic of PMCU's core packaging layer through external ports.

Independently proving complex major mathematical theorems without the guidance of human intuition.

Forcibly training anthropomorphic general large models (LLMs) in environments lacking computing centers.

The most important point: it could never replace Jiang Lin's core judgment as a human in life-and-death strategic choices.

Years passed amid the roar of cooling pumps and the alternation of code.

By the thirty-fifth year, due to the continuous evolution of MPS-Agent α's retrieval and stitching capabilities, those local cache fragments of PMCU-17 that originally looked like they were torn apart by a storm finally began to be indexed over the long term under the timeline and probability model, piecing together some deeper directory structures.

Mm, what MPS-Agent α did in the background was clumsy and protracted.

It was like trying to piece tens of thousands of shattered glass fragments back into a mirror in the mud after a heavy rainstorm.

It used greedy algorithms to attempt restoring the tree directory structure.

Using the logical increment of timestamps to sort out the time-reversed order of massive logs.

Forcibly aligning those hexadecimal task numbers that only had half left via regular expressions.

Comparing hash values of incomplete filenames between different fragments.

Most crucially, it projected those high-risk historical records showing data synchronization failures, along with PMCU-17's own maintenance Physics status codes at the time, into the same high-dimensional scatter plot to search for accompanying relationships.

Many retrieved fragment files, after hexadecimal conversion, only left a few unreadable garbled characters.

Many text summaries regarding major tasks were rudely cut off at key verbs and nouns, leaving less than half of the content.

Countless filenames looked like password slips instantly burned through by high-temperature plasma, leaving only charred edges.

However, when these slips of paper representing historical relics were stacked, filtered, and reorganized tens of thousands of times through algorithms, a startlingly small edge of history's massive outline finally emerged in the white light of the screen.

The first batch of system-level keywords that truly made Jiang Lin stop all his work and hold his breath to stare at them appeared in the long winter of the thirty-sixth year.

After weeks of data cleansing, the terminal slowly refreshed with several severely damaged string identifiers.

[ FDSO-2076 A ]

[ Heliospheric Outer Layer Dust Spectrum Anomaly: Real-time Correction Plan for High-Risk Particle Size Segments ]

[ Heliospheric Physics Boundary: Solar Wind-Interstellar Medium Coupled Compression Response ]

[ Earth-Moon Orbit Layer: High-Speed Particle Flux Peak-Shaving Window ]

[ Node Facility: Seventh Canopy Station ]

[ Deep Space Topology: Far Side of the Moon Observation Array Link ]

[ High-Latency Node: Mars Joseph-Louis Lagrange Point Microwave Relay ]

[ Ultimate Contingency Plan: Civilization Spark-Level Data High-Dimensional Compression Backup Protocol ]

Initially, Jiang Lin had no idea what physical entity the abbreviation FDSO represented.

Judging from the rigorous nomenclature of the -2076A suffix, it did not look like a disaster code for a hurricane, tsunami, earthquake, or regional pollution accident.

Nor did it look like the engineering code of a weapon of mass destruction launched by some crazy country.

Even less likely was it some ordinary underground facility code internal to the Canopy Project.

Because appearing alongside it were words of extremely unusual scales, such as the outer heliosphere, dust spectrum, heliospheric boundary, far side of the moon observation array, and Mars relay.

These words pulled the boundaries of the problem directly from the surface to the entire inner solar system, and even further.

In the long two years that followed, MPS-Agent α acted like a tireless gold miner, piecing together more fragmented file names with contextual meaning from the data ruins.

[ High Priority Warning: FDSO-2076 A / Main Front Particle Size Spectrum Correction Enters Irreversible Window ]

[ Astrophysical Calculation: Heliospheric Boundary Strong Compression Response Model / Core Calculation Fragments ]

[ Impact Risk Assessment: Upward Revision of 100-Micron to Millimeter-Scale Particle Flux Anomalies ]

[ Network Status Log: Far Side of the Moon Background Star Occlusion Observation Link / Non-Response (Timeout Judgment) ]

[ Deep Space Communication Log: Mars Relay Node / Signal Completely Lost (Link Physics Damage Probability 98%) ]

[ Core Encapsulation Layer Behavior: Civilization Data High-Dimensional Compression Protocol / Partial Synchronization Failure with Underground Main Array (Due to Outer Ring Physics Damage) ]

[ Hardware Level Alarm: TM-7 Regional Computing Array Outer Ring Phase Change Cooling System... Complete Collapse and Failure ]

Late one night, the starlight outside the Outpost was dim.

Jiang Lin picked up a charcoal pencil and walked over to the north wall that recorded the half-life efforts of his current round of Wasteland seclusion.

On this mottled wall, he began to copy down line by line the fragmented file names he had traded a massive amount of time for.

With each line he copied, the problem tree on the north wall, formed by black lines and concerning the causes of the Wasteland catastrophe, expanded outward by a full circle toward the abyss of the universe at a suffocating speed.

Node Layer 1: Ruins of Seventh Canopy Station.

Node Layer 2: Far Side of the Moon Observation Array Link.

Node Layer 3: Mars Joseph-Louis Lagrange Point Microwave Relay.

Node Layer 4: Civilization Data High-Dimensional Compression Backup Protocol.

Support System: TM-7 Regional Underground Computing Array.

Peripheral Remnants: PMCU-17 Outer Ring Maintenance Computing Unit.

At this step, Jiang Lin realized that TM-7 might not solely refer to the Seventh Canopy Station on the surface.

Seventh Canopy Station might just be the external manifestation node.

What truly undertook the tasks of long-term calculation, data synchronization, regional disaster modeling, and civilization data caching was the regional computing array buried deep underground.

And PMCU-17 was merely a piece of debris torn out from the outer ring maintenance system of this massive array by stratum collapse, cooling collapse, and long-term power failure.

Jiang Lin took two steps back and stared at the black handwriting covering the wall.

These vocabulary words could perhaps explain why optical fibers buried deep underground appeared near Seventh Canopy Station.

They could also explain why a site that looked like a surface monitoring station appeared simultaneously with the far side of the moon observation link, Mars relay, and underground main array in the same batch of damaged caches.

That was not an ordinary hydrological station.

Not an ordinary meteorological station.

Nor was it an observatory in the pure sense.

It was more like the surface terminal node of some giant disaster response system.

The tentacles of this system spanned the surface, underground computing array, near-Earth space, far side of the moon observation link, and Mars relay.

It was not built to record a single short-lived disaster.

It was more like it was meant to track a deep space target that was continuously approaching, continuously correcting, and continuously changing its risk model.

By the thirty-eighth year, with the accumulation of database computing power, MPS-Agent α, based on the task nature classifications of thousands of entries, fragmented Physics formula summaries, co-occurrence relationships of astronomical terms, and the position of FDSO in multiple directories, invoked a linguistic probability model, and finally presented a low-confidence yet spine-chilling engineering-level candidate explanation on the main screen.

Only a line of green Songti characters flickered on the screen.

[ Semantic Reconstruction Deduction: FDSO-2076 A —— Suspected Filamentary Dust-Stream Overdensity / Filamentary Dust-Stream Overdensity ]

Below was another smaller note.

[ Note: This expansion is only an abbreviation candidate reconstruction and does not constitute the decryption of the original naming. ]

When these words came into view, Jiang Lin sat before the faint fluorescence, maintaining his original posture as if his entire person had been frozen in time.

Not an asteroid impact with crossed orbits.

Not a thermonuclear war triggered by human stupidity and greed.

Not a global ecological and climatic collapse purely caused by the greenhouse effect.

Nor was it a short and fatal gamma-ray burst impact descending from the sky.

If this statistical-based semantic reconstruction of MPS-Agent α possessed a degree of correctness at the Physics level, then what this Wasteland once faced was likely not a single object crashing into it.

But rather a dim, slender, low-optical-thickness interstellar dust stream crossing the solar system at high speed.

It did not need to be as bright as a comet.

It did not need to drag a wake in the night sky.

It did not even need to possess a stable visible boundary.

The truly dangerous part of it might not necessarily be the total mass.

But rather the particle size spectrum.

The abnormal proportion of particles ranging from a hundred microns to the millimeter scale.

The relative velocity.

The flux.

The duration.

It was these things, so tiny they were invisible to the naked eye, continuously passing through the orbital layers, upper atmosphere, lunar surface facilities, deep space probes, solar wings, optical windows, radiators, and ultimately dragging the surface water cycle into an abnormal state via atmospheric chemistry and radiation budgets over the scale of years, decades, and centuries.

What was even more troublesome was that if FDSO was not simply a solid dust stream, but a fibrous super-density structure entraining neutral gases, charged particles, dense interstellar media, and local interstellar magnetic field disturbances, then what it affected was not just spacecraft hulls, but the entire heliospheric boundary conditions.

This could perhaps explain why the Canopy Project required the far side of the moon observation link.

Because if the target itself was dim enough, telescopes on Earth might not be able to directly see it.

Humanity could only indirectly lock onto its existence through the weak occlusion of background star fields, infrared scattering residuals, dust counter saturation curves, spacecraft hull micrometeoroid pit rates, charged particle environment sudden changes, and multi-station phase differences.

The far side of the moon was not meant to directly see the Dark Dust String.

But rather to capture those extremely weak indirect observation signals in an environment without Earth's atmospheric disturbances, without complex radio noise, and far from the fragmentation risks of early near-Earth orbits.

Because Earth's atmosphere was too thick.

The radio environment was too dirty.

And near-Earth orbits were too easily damaged by the earliest batch of high-speed particles.

This could also explain why words such as tidal wave front, phase difference calibration, and multi-loop coupled response repeatedly appeared.

The so-called tidal wave might not be seawater.

Nor was it a pure gravitational tide.

It was more likely an internal designation by the future engineering system for the leading-edge disturbance of the Dark Dust String.

A leading edge jointly formed by dust streams, charged particles, solar wind boundary compression, heliospheric magnetic field disturbances, and upper atmospheric responses.

If this hypothesis held true, the catastrophe did not stem from a single impact.

It was more like a cosmic-scale sandstorm.

Filing its way from beyond the boundaries of the solar system all the way into the Earth-Moon system.

What was filed down and ruined first might not be cities.

But probes.

Deep space antennas.

The far side of the moon array.

High-orbit communication links.

Solar wings.

Optical windows.

Low-orbit satellites.

And those fragile boundaries in the upper atmosphere that ordinary people could never see, yet which supported modern civilization.

Because of the abnormal high-speed particle flux, Earth's orbit was no longer safe.

Because the heliospheric boundary was compressed and disturbed, the coupling among the solar wind, interstellar medium, and Earth's magnetosphere entered an abnormal state.

Because charged particles and high-risk particle size segments existed within the dust stream, the lifespan of equipment exposed to near-Earth space for long periods was systematically compressed.

Because the atmosphere blocked the vast majority of particles, it was also forced to endure long-term high-altitude ablation, metal ion injection, rising aerosol loads, and ozone chemical disturbances.

When this process continued for years, decades, or even longer, the atmosphere itself would transform from a protective layer into a reaction field that slowly accumulated consequences.

Because orbital links were gradually broken through, deeper space nodes like the Mars Joseph-Louis Lagrange point were incorporated into the civilization data relay system.

Jiang Lin wrote these possibilities on the wall one by one.

With each one he wrote, he added a question mark behind it.

He did not allow himself to erase the question marks.

Because as an engineer who used code and formulas to measure living space on the Wasteland, he knew very well that everything before him was still merely a system hypothesis.

The existing chain of evidence was riddled with holes.

Original data was severely lacking.

The contextual environment was severed.

The expansion of FDSO came from a probability model rather than the original archive title.

PMCU-17 was also not the general archive of the civilization's doom.

Pathetically, it was merely a maintenance cache, an outer ring maintenance computing unit.

What it was truly responsible for recording originally might only have been cooling circuit temperatures, pump group speeds, local power supply status, fault handshake failures, data synchronization retry counts, and cache queue anomalies.

It was not qualified to write an epitaph for the entire human civilization.

This machine would not tell Jiang Lin when the Dark Dust String was finally confirmed.

It would not tell him whether those Outpost probes had ever truly passed through the leading edge of that dust stream.

It would not tell him whether the far side of the moon observation link fell silent due to particle impacts, power supply ruptures, link destruction, or loss of contact with Earth's main array.

It would not tell him whether the Mars relay successfully forwarded that civilization spark-level high-dimensional compressed data to a more distant node before completely losing signal.

Even less would it tell him whether humanity, in this Wasteland World worn through by the interstellar dust stream, had ever found a true path to survival at the final moment.

It only had cold hexadecimal fragments, incomplete directories, and a few keywords squeezed out from the underlying maintenance logs.

Only an unfathomable Physics direction.

Jiang Lin stood before the north wall, looking at those fragmented words and question marks.

A long time later, he wrote on the very last line in an extremely restrained handwriting: [Hypothesis: The destruction of this Wasteland civilization may be related to a string-like high-speed interstellar dust stream crossing event approaching from beyond the boundaries of the solar system.]

He paused for a moment and added below.

[Tentative Name: Dark Dust String.]

On the next line down.

[The primary kill mechanism should not temporarily be attributed to a single impact or a single gravitational disturbance. It is more likely: particle size spectrum anomaly + high-speed particle flux + heliospheric/magnetospheric coupling anomaly + orbital asset cascading destruction + long-term degradation of atmospheric chemistry and water cycle.]

On the final line, he wrote only two words.

[Hypothesis.]

The wind outside the window stopped.

The cooling pump emitted a low hum underground.

Jiang Lin closed his eyes, but an ice-cold picture uncontrollably emerged in his mind.

Beyond the edge of the solar system, a dust string, so dim it was almost invisible, was slowly crossing all of humanity's observation coordinates.

It had no light, no sound, and no hostility.

Nor would it deviate slightly from its path just because humanity understood it.

It simply carried those tiny, hard, high-speed particles, advancing forward according to mass, velocity, flux, and time.
