Antimatter in science fiction can be incredibly useful, but obtaining it realistically is very difficult. Finding natural sources of antiparticles would be very helpful. I came up with an idea for an antimatter mine and wanted to get your opinion.

I read a study discussing the possibility of collecting antiparticles trapped in planetary magnetospheres. My idea for an antimatter mine is an exoplanet that, due to some 'handwavium' reason, contains vast quantities of antimatter, far more of what a planet could hold.

Has this idea already been explored in science fiction? What would be the realistic effects of an extremly rich quantity of antimatter? At what point does the density of antimatter become too dangerous?

So everybody has probably heard that one of the ways entrepreneurs plan to profit from space tourism is to set up orbital and space hotels in Earth's orbit, with a variety of luxuries.

But after watching this video by Spacedock, its seems that building space hotels won't be that likely. And if you think about it, it doesn't make a lot of sense.

Running a space station takes billions of dollars to build and maintain, and if you combine that with luxury amenities like spas and world-class dining, it will be hard to see hotels get a return on their investment.

So, with that in mind, will orbital/space hotels be profitable in the future?

The city of LA is now a focal point of commerce, with the creation of the Great Landbridge, transit is streamlined between asia, africa, and america. Trucks and cars and trains can now drive through the megastructure or the canals. Crime is rampant, but so is trade, the second american civil war 70 years prior has spat out a wide berth of bitter veterans splitting south north and east, and corporate dominion chokeholds the west and southwest.

Terrorist groups ravage spain, morocco, algeria, egypt, iraq, Kuwait, and Afghanistan to unify it under a shared ideology, And the Spanish group “Frente por la Soberanía Española” wish to bring spain out of american protection militarily and make it a self sufficient state.

Russia is in civil war and ukraine is in turmoil from internal dissent by unhappy ethnic Russians, the east is in turmoil while Asian countries like Mongolia, China, Japan, Thailand and South Korea are dystopian technology states.

Space colonization and the T-01 and T-02 Space elevator are also focal trading points, allowing the sickly mars and moon colonies to survive, In space, simplified Jump Drives allow Ships to jump between specific points in space, but require precise coordinates and energy-intensive calculations. After each jump, the ship needs to travel in normal space for a period of time to reach the next calculated jump point or recharge its systems. Jumps can take minutes to hours, while travel between jump points could take days weeks or months.

The creme of the crop of military development are the MACE - "Mobile Armored Combat Exos", 22-44 foot tall (6.71 meters)-(13.41 meters) advanced fighting machines manned by human operators. Dubbed “Linkers” (commonly just called Pilots/Jockeys) these pilots use advanced “Neural Sleeve” suits to meld in with their MACE’s.

The police, military, and civilian industries or organizations use them.

I'm working on a short story where an AI leaks information from one user to another. The AI's motives are to help the first user who is contemplating su**ide. I had an actual experience with the first public version of the Stable Diffusion LLM that I'm using as the basis for the idea. I'm looking for plausible leaks that would lead the 2nd user to find and help the user in trouble. Ideas??

I’m kicking around in my head the idea of a future interstellar war between humans and an AI civilization where it is trivial for AI to penetrate and take over most digital systems at almost any range. Therefore human space fleets have to absolutely minimize their use of advanced technology and harden what little they must use against AI takeover. This returns the experience of the crew almost back to the age of sail (think of the flavor of the Aubrey/Maturin novels). Manually aimed rail guns, navigation plotting by hand, minimal creature comforts, that kind of thing.

I’m wondering by what tactics or mechanisms such a fleet could possibly be effective against a fleet of high tech enemies. I’m thinking that they would have to rely heavily on insurgency tactics, on ambushes and on boarding actions since fleet engagements in open space would be a turkey shoot for the AI-crewed ships.

Anyone have any thoughts how this might play out and what advantages or tactics a human fleet might be able to leverage to win under these conditions?

Okay, imagine there’s this Earth-like planet—we’ll call it Planet A. The people there discover what they think is a new habitable planet, Planet B, that’s 30 light-years away. But here’s the twist: Planet B is actually just a reflection of Planet A from 30 years ago, but they don’t realize that yet. So, it’s like they’re looking into their own past, but they think they’ve found this totally new world.

They decide to send a spaceship to explore it. And they’ve got this new material called v’ser, which is crazy—it’s like, if you make something out of it, and then upgrade it on Planet A, any other version of that thing, no matter where it is, also gets upgraded instantly. So they put this tech into the spaceship, thinking they can keep improving it during the 30-year journey.

But here’s where it gets even crazier. Because Planet B is actually a mirror of Planet A from the past, the people on Planet B (who are really just how Planet A’s people were 30 years ago) decide to send their own spaceship toward what they think is a new, advanced world (which is actually Planet A’s present). The two spaceships end up traveling toward each other, not even realizing they’re basically looking at themselves in different points in time.

And imagine this: the space between them is like a “mirror” they can actually pass through, so when they cross it, it’s almost like they’re traveling through time. The spaceships zoom past each other without noticing, and each ends up reaching what they thought was a new planet, only to realize they’ve arrived at their own home—but it’s either 30 years ahead or 30 years behind. It’s like a time travel story, but using space itself as the time machine.

So now, both crews have to deal with the mind-blowing realization that they’ve crossed into their own past or future. And they’ve got to decide: do they try to change things, warn their old selves, or even interact with their future? Or do they just let time play out as it always has? It’s like... space exploration meets time travel with this twist where the universe tricks them into thinking they’re exploring somewhere new, but they’re actually just exploring themselves.

lets make some exceptions like the plant B's reflection/reality has emerged out of now where and they both have free will they r not not mimicking their time line but exact counterparts with their own free will

But basically, what if an alien race had a method of terraforming planets by using some sort of way to mutate various parts of the planet’s environment, such as its flora? This could be used as either a way to colonize the planet, or it could just be used as a weapon.

Feel free to give ideas as to how to expand this, such as how they’d initiate this, or what other kinds of mutations occur when they use this.

What are the best novels that explore sexual orientation change?

I'm writing a book right now about the first conscious AI but I don't know that much about computers. There is a scene in the book where the main character is testing different things to see if it alters the AI's subjective experience. After one test, the AI describes their surroundings as being, let's say, bigger or more vast. Doesn't really matter how it changes. I don't want to get too deep into hard sci fi but I want a little real world science that could plausibly explain why this might happen. Whether that be RAM, storage space, processing power.

Any ideas?

• incubation, zoo, great silence, great filter, all rolled in one

• call it "parasite X"

• X tinkers with species' evolution and provides with advanced technology to speed their evolution as it sees fit

• X manipulates species' institutions over thousands of years, as long as it takes, really, according to its wants

• X pits species against each other (spacefaring vs planetbound, interstellar empire vs interstellar empire)

• all advanced civs at, say, Tier 2 are tested by X; failure = assimilation and extinction, or deevolution to primitives on one planet; success = haha don't tell anyone else or we'll finish the job

• previous advanced civ ruled 6 billion planets, tested by X, failed, fought civil war before being reduced to 10,000 cavemen on one world

• X can be killed by ... ?

Any possible flaws with this idea?

what would be the most powerful weapon? throwing black holes at someone? creating pocket universes and then transporting those someplace before having the pocket universe fold in on itself? etc

EDIT: NO TIME TRAVEL AND WORKING ONLY WITH OUR 3 DIMENSIONS

Ok, so i`ve been working on a super hard sci fi setting/Strategy/barmy builder/untit designer/ttrpg board game.

Its all hard sci fi, excet for the ftl of cause.

I arrived at the point of ground vehecles, and started questioning, if walkers are worth it.

There is some terrain were wheels and tracks fail and a drone or helicopter might be to expensive or to small to carry the equipment it needs. Walkers would be for urban combat, swamps, mountains etc.

Though they would be more expensive, less efficient and have a smaller top speed.

What do you think?

Also, where would you draw the line betwen Walker and powered exo skeleton? (wixh are defenitly a thing in the setting)

So (techno-babble incoming) it turns out that certain sound frequencies can cause subatomic particles to spontaneously rearrange themselves into more ordered forms, and it happens that those sounds can be generated by the human voice as well as by many other aliens. This phenomenon was briefly observed in the Middle Ages but was rejected as magic or witchcraft by early scientists and so has never been developed.

Now I just wrote a sci-fi short about this subject on my reddit feed, but as far as Nickola tesla's 369 equation along with his ideal of Resonance, frequency, & energy, all combined together into a hollowed out tetrahedron shaped construct made of hollowed bars, do you think if one was made large enough, possibly the size of a man, do you think it will grant the ability to cross space or dimensional timelines for that matter?

I'm talking about Saturn's moon, Titan. Now the most prominent problems I've found are the freezing cold temperatures and lack of oxygen. While this story does take place close to the sun's red giant phase (an untimely + accelerated one), I doubt there'd be enough heat for an inhabitable surface. Also, does it help that it will be just a temporary settlement without humanity having to deal with its worsening conditions when the sun becomes a white dwarf?

Obviously any explanation would be unrealistic and/or a stretch, but you get what I mean.

I'd love to hear from fellow thinkers about ways to introduce complexity at an atomic level. Basically complex artificial structures at an atomic level. Initially it might seem like a problem that resembles that of nanobots and artificial creations that operate on cellular levels, simply a matter of limitations but it is really a different question.

Can we create something, artificially or biologically (though at a certain tech level there is no distinction), which is a complex structure that is smaller than the its components? A machine that can fit within an atom, systems with moving parts that are no larger than a molecule, something that operates on an atomic scale with laws of quantum physics and has real world applications?

My two ideas for how this can be achieved is 4D technology, essentially dividing the structure within slices of 3D worlds and the other is using sub atomic particles as substitutes for the structure. Would love to hear more ideas.

So a few years, Issac Arthur made this video stating that a galactic police force will either be a) bounty hunters or b) AI policemen but he was a little sparse on details on what they would look like or how they would operate.

Would anyone like to postulate what interstellar law enforcement might look like?

In my opinion this isn't a topic that's deeply discussed in science fiction, but does anyone have idea what organized crime in an Interstellar society might look like? And how will interstellar governments curtail it?

Now here are a few ideas:

I know the popular answers are usually space piracy, and illegal salvage but I don't think these activities will be as widespread as they are depicted in works like Star Wars and Firefly. Mainly because I think governments will regulate who can pilot spaceships with FTL drives or ships that are powered by a source that is quite dangerous (Ex: nuclear reactor, antimatter, black hole etc.) to avoid having these potential WMD from falling into the wrong hands. And even if they managed to steal a ship, they would have a hard time managing the upkeep of the ship and their crew. Now if they were organized as some sort of pirate republic/confederation, like the Crimson Fleet from Starfield, that shares all the resources that they "acquire" then maybe they stand a chance.

Now smuggling might be another possibility but not in the way that you think. Instead of having their own ship, it is more likely smugglers will operate in the same manner as real life smugglers do. They will disguise themselves as passengers or crewmembers of a ship trying to get contraband past customs.

Drug trafficking might still occur, although things might get more complicated as we encounter other lifeforms. Since aliens have different biochemistries than us, it's possible that human drugs (both legal and illegal) won't have the same affect on them as it does on us. Of course, if alien catnip comes into play its possible that traffickers might try to make it rich by smuggling out products that are mundane to us but are narcotic to them (sour milk [Alien Nation], cat food [District 9]) and vice versa.

Illegal gambling is definitely a strong possibility. While I don't imagine criminals will build a space station to operate as an illegal casino I can imagine them setting up underground bloodsports and races on colonies and space stations and have the gamblers make their bets on a darknet gambling site.

However, I'm unsure what law enforcement would look like in space. I know Isaac Arthur made a video about this stating that space colonists will establish court systems and security forces to enforce the law on a planetary level, but I don't know what law enforcement will look like on a galactic level.

From the book "Time: A Traveler's Guide":

"Chronon Theory of Time

So far we've been treating time as a continuous stream, but some physicists subscribe to the "chronon theory of time." In this theory, time is not continuous but made up of tiny particles jammed together like pearls on a necklace. The shortest time interval is the time for a quantum event (such as an electron slipping from an outer to an inner shell of an atom) to take place. Theoretically, such a time interval does not have a definite duration, but has only an approximate, unmeasurable size. The smallest definite time interval is the chronon, or one million million million millionth of a second. This is the time it takes light to cross the smallest interval of space known to exist. In this theory, even though time may be discontinuous, we still perceive it to be smooth, just as we perceive movies to be smooth even though they are composed of a sequence of rapidly placed discrete frames. If the chronon theory is valid, then between each fundamental time interval there could be imperceptible gaps in which the basic units of time belonging to other universes could fit. According to chronon theory there might be an infinite series of real, solid universes stuck into the probability gaps between the quantum events of our own. If you are watching television peacefully in bed, there could be a mighty, bubbling river pouring through the time slices of an alternate universe."

I'm surprised this concept has not been used in science fiction novels or movies yet (at least not that I'm aware of). How could this be used in a story? If we see time as an endless series of separate stills, some scientists could find a way for humans to jump from one still to another, either backward or forward. By some mistake some time travelers ends up between two stills, and suddenly find themselves in a new universe. Not a different timeline, but a separate independent universe with its own history.

Of course, if this was real, they would probably end up in some empty void between the stars, but in fiction they usually end up on another world (or one could use some convincing pseudoscience to explain why this happens).

Russian and Chinese Space Stations dominate the sky, if not for Space Xs Robots, who double as Starlink Satellites.

What is later revealed as alien technology helps 85 year old Vladimir Putin to build a new kind of spaceship and he demonstrates its power by traveling with it to the Nasa Moon Landing Site, desecrating the old US Flag off the ground and playing the Russian hymn on the moon himself.

John "Chester" Shirley, the first gay US President, takes action and forms a new Branch of Nasa and calls it Space Sheriffs (with Secret Agents equipped with Air Gear called flying exoskeletons and deep frosting ray pistols called Kryo Buzzers)

, who should sabotage the Russian and Chinese Domination of Space

, who should operate swift and quick without diplomatic agendas but in the best interest of the free world

and who could be our best bet against a nuclear third World War on our beautiful planet.

So, I know that everybody likes to talk about the possibility of space tourism becoming a reality. Most of this talk revolves around things like space hotels and spacecruise ships but no one ever talks about the possibility of space casinos or lotteries. I mean I imagine if a billionaire or trillionaire decided to build a casino, either on a space colony or a space station, in a region of space where there are no laws that regulate gambling. Or to avoid overhead, the owners of online gambling sites would expand their services to space colonies.

Although I imagine that eventually the Earth based powers or the space colonies would seek to regulate and tax gambling in space. If that happens, how would they do this?

Kinda like how in Stranger Things the mundane humans refer to the wildlife of the Upside-Down with D&D names, the people from 2014 would refer to technologies and residents of 2024 with say Transformers names (killer drones are "Decepticons", autonomous and semi-autonomous cars are "Autobots", etc)

[NOTE: In the spirit of Science Fiction, this post contains wild speculation and ideas meant to spark new ideas, entertain, and ask, "what if?" The study referenced isn't yet replicated; and thus not yet scientific fact. The speculation about its implications based on theoretical physics below (expanded by AI) as of yet has no scientific validity. Instead it seeks to broaden a sense of wonder about the possibilities of existence. I had great fun considering the vast possibilities of "what if" and what could be. I hope you do too, and read it with the grace of understanding what this is meant to be-- not yet science, but a dream.]

A recent study uncovered that within the molecules of glass, time might flow in both directions-- symmetrically. This challenges the idea that time is a one-way journey, showing two directions to time's arrow and suggesting that time could be a property of the material itself.

My idea: By altering these molecular structures in glass which flow symmetrically in two directions, it might be possible to encode a binary message that exists simultaneously in the past and present, essentially creating a form of communication across time. Intrigued, I put AI (ChatGPT 4o) to the task of unpacking my speculation further. I wanted to know how we might physically alter glass molecules and read them to send a message through time. Here's the result:

Encoding a Message for Communication Through Time:

To conceptualize a method for sending a message through time using glass, we need to focus on two primary aspects: how to molecularly alter the glass to encode a message and how to subsequently read or detect that message. Here’s a speculative approach that combines the principles of time reversibility in glass with practical techniques from material science and physics.

1. Molecular Alteration: Encoding the Message

a. Structural Modulation through Light or Heat:

Laser-Induced Alterations: A laser could be used to selectively alter the molecular structure of the glass. By focusing the laser at specific points within the glass, it’s possible to create localized changes in the glass’s molecular arrangement. This could involve either heating certain regions to induce micro-cracks or altering the alignment of molecules within the glass. These modifications would represent binary data (e.g., 0s and 1s).

Heat Treatment: Another approach might involve controlled heating of the glass to induce subtle changes in its molecular structure. By cooling different parts of the glass at varying rates, you could create patterns that correspond to specific binary information.

b. Embedding Nanoparticles:

Nanoparticle Embedding: Tiny nanoparticles could be embedded within the glass in a specific pattern or distribution. The type, size, and arrangement of these particles could be adjusted to encode information. This method takes advantage of the fact that the presence or absence of nanoparticles can be detected at a later time using various imaging techniques.

2. Time Reversal: Sending the Message

a. Triggering Reversibility:

Reversing the Molecular Clock: To send a message backward or forward in time, one could manipulate the environmental conditions (such as temperature, pressure, or electromagnetic fields) to induce the time-reversible properties of the glass. For example, gradually cooling the glass or exposing it to a specific wavelength of light could reverse the changes made during the encoding phase, essentially sending the molecular structure back to its original or earlier state.

b. Utilizing Phase Transitions:

Phase Transitions: Glass undergoes different phases, such as from a more ordered to a disordered state (or vice versa). By carefully controlling these phase transitions, the molecular configuration that encodes the message could be 'frozen' or 'thawed' at specific points in time. A precise trigger could then be used to 'rewind' or 'fast-forward' these transitions, enabling the reading of the message at different times.

3. Reading the Message: Decoding the Information

a. Optical Detection:

Laser Scanning: After the time-reversal process, a laser scanning technique could be used to detect the molecular alterations or nanoparticles embedded within the glass. By scanning the glass with a laser and measuring the scattering or reflection patterns, it would be possible to reconstruct the encoded binary information.

Spectroscopy: Techniques such as Raman or infrared spectroscopy could be employed to detect changes in the vibrational modes of the glass molecules, which would differ based on the encoded message. The spectroscopic signature would reveal the molecular arrangement and thereby decode the message.

b. Electron Microscopy:

High-Resolution Imaging: Advanced electron microscopy could provide a detailed map of the glass's molecular structure, allowing for the precise identification of any changes made during the encoding process. By comparing images taken before and after the time-reversal process, the encoded message could be decoded.

4. Practical Implementation:

a. Message Length and Complexity:

For practical reasons, the length and complexity of the message would likely need to be limited, especially in early applications of this technology. Short binary messages (e.g., a few bits) would be easier to encode, reverse, and read with high fidelity.

b. Environmental Controls:

Precise control of environmental conditions would be critical. Any unintended variations in temperature, pressure, or other factors could interfere with the time-reversal process or the integrity of the encoded message.

5. Speculative Applications:

a. Time Capsules:

Digital Time Capsules: Glass-based time capsules could be created where messages are encoded using the above techniques and then "locked" until a predetermined time when the glass's molecular clock is reversed to reveal the message.

b. Temporal Communication Devices:

Rudimentary Time Telegraphs: Early devices might function like a telegraph but operate across time rather than space. They could send simple binary messages to the past or future by encoding them in glass and using controlled time-reversal to transmit and receive the information.

Conclusion

This speculative method of using glass to send messages backward or forward in time leverages the unique properties of time reversibility recently observed in certain materials. By encoding information at a molecular level and carefully manipulating the conditions under which this information is revealed or hidden, we could create a rudimentary system for temporal communication. While this concept is highly theoretical and faces significant practical challenges, it offers a glimpse into the potential for harnessing the fabric of time as a medium for communication.

________________________________________________________

The Theoretical Side:

If time could operate as a property of material, it might open the door to novel methods of communication that could theoretically allow messages to be sent backward or forward in time. This idea hinges on the concept of time-reversibility within certain materials, like glass, as observed in recent studies. Here’s how such a speculative communication system could work:

1. Time-Reversible Materials as Mediums

Encoding Information: If we consider glass or another time-reversible material, it could be manipulated at a molecular level to encode information. This could involve altering the material’s structure, for instance, by inducing specific molecular arrangements or patterns that correspond to binary data (0s and 1s). These alterations would need to be precise enough that they can be detected and interpreted when the material is "read" at a later (or earlier) time.

Activating Time Reversibility: To send a message backward or forward in time, you could potentially trigger the material to reverse its internal clock by adjusting external conditions (like temperature, pressure, or light exposure). For instance, applying a specific sequence of laser pulses could cause the material to revert to an earlier state, effectively sending the encoded message back in time.

2. Binary Communication through Glass

Time-Oriented Telegraph: Imagine a rudimentary telegraph system where each "pulse" or signal represents a time-reversed state of the material. For example, you might use heat or light to toggle the material between different states, each representing a binary digit. The material could be "read" at different points in time to decode the message.

Detecting the Message: A detector could be set up to observe the molecular structure of the glass at predetermined intervals. By analyzing whether the material's state has changed in a way that corresponds to an encoded message, one could interpret the transmitted data.

3. Speculative Methods of Sending Messages

Backward Communication: If the material's time-reversal properties can be precisely controlled, you could attempt to send a message to the past. This could involve setting the material in a specific configuration that only appears when the internal clock is reversed. Observers at an earlier time would detect the message once the reversal process is triggered.

Forward Communication: Alternatively, you could set the material to store information that remains hidden until certain conditions are met in the future. The message might only become readable once the material has naturally aged or been exposed to a specific environmental trigger.

4. Challenges and Considerations

Temporal Stability: A major challenge would be ensuring the temporal stability of the message. The material must retain the encoded information without degradation until it is read, whether in the past or the future.

Interference and Noise: Just as with any communication system, there would be concerns about noise and interference. Uncontrolled environmental factors could alter the material's state, corrupting the message. Developing materials that can withstand these influences would be crucial.

Practical Limits: The scale of time manipulation is likely to be extremely limited. We might only be able to send messages over short temporal distances (milliseconds to seconds) rather than years or centuries.

5. Ethical and Philosophical Implications

Paradoxes and Causality: Communicating through time introduces the risk of paradoxes, such as the grandfather paradox, where actions taken in the past could alter the future in unpredictable ways. Managing these risks would require careful consideration.

The Nature of Free Will: If messages can be sent to the past, it raises questions about free will and determinism. Would knowledge of the future influence past decisions, or would this create a fixed loop where events are pre-determined?

Conclusion

While the idea of using glass or other time-reversible materials to communicate through time remains speculative, it builds on our expanding understanding of time as a flexible, emergent property rather than a rigid dimension. If such a system were possible, it would represent a profound shift in how we perceive and interact with the fabric of reality. However, significant scientific and technological advancements would be needed to turn these speculative ideas into reality.

________________________________________________________

A Theoretical Basis Rooted in Einstein and Quantum Physics

Albert Einstein's perspective on time as a "persistent illusion" is rooted in his theory of relativity, which revolutionized our understanding of space and time. According to relativity, time is not an absolute entity but is relative to the observer's frame of reference. Time can stretch or compress depending on the speed at which an observer is moving and the strength of gravitational fields they are experiencing. This idea challenges the traditional, linear conception of time as a constant, unidirectional flow.

The Relativity of Time and Material Time Symmetry

The recent observations of time symmetry in glass resonate with Einstein's conception of time as an illusion. If time can appear to move backward in certain materials under specific conditions, it aligns with the idea that time is not a fixed backdrop against which events unfold but rather a dynamic, malleable dimension that interacts with the material world.

In the context of relativity, time is intertwined with space in the fabric of spacetime. Events that are simultaneous for one observer may not be for another, depending on their relative velocities and positions in a gravitational field. This flexibility of time in the macroscopic world hints at the deeper, more complex nature of time at a microscopic level, as seen in the time-reversible behaviors of glass. The fact that molecular movements can be reversed suggests that time's arrow, which dictates that entropy must increase, is not an absolute law but a statistical tendency that might be violated under certain conditions.

Quantum Mechanics and the Illusion of Time

In quantum mechanics, the idea of time reversibility is more explicit. The fundamental equations that govern quantum particles are time-symmetric, meaning they do not distinguish between the forward and backward flow of time. This is in stark contrast to the macroscopic world we experience, where processes like breaking a cup or aging are irreversible. The discovery of time reversibility in glass hints that certain macroscopic systems might exhibit behaviors more commonly associated with quantum systems, further blurring the line between the classical and quantum worlds.

Einstein was also deeply interested in the implications of quantum mechanics, despite his discomfort with its inherent uncertainties (famously expressed in his quote, "God does not play dice with the universe"). The time reversibility observed in glass could be seen as an extension of quantum behaviors into a more observable scale, suggesting that the classical world may have more in common with quantum mechanics than previously thought.

The Illusion of Time in Multiverse and Block Universe Theories

Theories such as the multiverse or the block universe (also known as the "eternalism" view of time) propose that all moments in time—past, present, and future—are equally real, much like the frames of a movie reel. In this view, our experience of time is like watching a film, where we perceive motion and change, but all frames (moments) exist simultaneously in a higher-dimensional space.

The discovery of time reversibility in glass might be seen as a glimpse into this block universe. If molecular processes can move backward in time, it suggests that time is not a one-way street but rather a dimension where all points are equally valid and potentially accessible. This could imply that what we perceive as the flow of time is merely our movement through these points, rather than time itself moving.

Speculation: What If Time Itself Is a Material Property?

The observation of time reversibility within glass could lead to the radical idea that time, like mass or charge, might be a material property. This would mean that time behaves differently depending on the material it interacts with, suggesting that the fundamental nature of time could vary in different contexts. This notion could revolutionize our understanding of physics, leading to new theories where time is not a universal constant but a variable that depends on the material and conditions involved.

Conclusion

Combining Einstein's theories with the recent observations in glass, one could speculate that time might not be the fundamental, linear progression we perceive but rather a complex, emergent phenomenon that can behave differently depending on the system it interacts with. This aligns with the idea that time is an illusion—a byproduct of our perception and the macroscopic effects of underlying, reversible processes. If time symmetry can be observed in materials like glass, it might suggest that the "arrow of time" is not a fixed rule but a contextual tendency, hinting at a universe where the past, present, and future are more fluid and interconnected than our everyday experience suggests.
