Hello folks. I came up with this cool sci-fi drive system for spacecraft. It will not work in real life, but I want to use it in a sci-fi plot. I asked an AI to explain it.


Prompt: Explain how the fictional graviton displacement drive works on faster-than-light spacecraft, and how it produces muons as an unintended side effect that has to be mitigated by muon capture tech.


Response: The Graviton Displacement Drive (GDD) is a theoretical concept for achieving faster-than-light (FTL) travel in science fiction, often used in settings where conventional warp drives are not feasible or desired. Here's a simplified explanation of how it might work, along with its unintended side effect of producing muons and the mitigation technique using muon capture technology.
  1. How the GDD Works:
    • Basic Principle: The GDD manipulates gravity to create a "warp bubble" around a spaceship, effectively bending space-time to move the ship forward without needing to accelerate through traditional means like rocket engines.
    • Artificial Gravity Manipulation: The drive generates artificial gravitational fields using advanced technologies such as exotic matter, gravitonic emitters, or other speculative methods. These fields curve spacetime locally, creating a region of expanded space ahead of the ship and contracted space behind it.
    • Warp Bubble Formation: By carefully balancing these gravitational forces, a stable "warp bubble" forms around the vessel. This bubble moves at FTL speeds relative to local inertial frames, carrying the ship within it.
  2. Muon Production as an Unintended Side Effect:
    • High-Energy Interactions: The intense gravitational manipulation involved in forming and maintaining the warp bubble leads to high-energy interactions between particles in the surrounding vacuum of space. According to quantum field theory, virtual particle-antiparticle pairs can pop into existence from pure energy in these conditions.
    • Muon Pair Creation: Among these pair productions, some result in the creation of muons – heavy electrons with a short lifespan (~2.2 microseconds). In the extreme energies present near the GDD, these muons are produced copiously and continuously throughout the journey.
  3. Mitigation Using Muon Capture Technology:
    • Muon Shielding: To protect the crew and sensitive equipment onboard the spacecraft, muon shielding is employed. Materials with high atomic numbers, like lead or depleted uranium, absorb incoming muons, reducing their number reaching the interior of the ship.
    • Active Muon Capture Systems:Additionally, active systems are implemented to neutralize remaining muons:
      1. Electromagnetic Traps: Electromagnets guide stray muons towards dedicated traps, where they decay harmlessly.
      2. Antimuon Annihilation: Antimatter-based systems generate antimuons (antielectrons), which annihilate any nearby muons upon contact, converting both into pure energy.
      3. Muon Decay Catalyzers: Special materials catalyze the decay process, causing muons to disintegrate more quickly than usual before they reach inhabited areas.
By employing these techniques, spacecraft equipped with GDDs can mitigate the harmful effects of muon production, ensuring safe interstellar travel despite this unwanted consequence of FTL travel.

For a parody version, instead of muons, just replace with "moo" or "cow" then imagine a microscopic wheel with a hamster in it.
Haha, that would be funny. The regular version is meant to be mostly serious.

Also, here is my scale of speeds in the sci-fi plot, if I ever start the plot. Note how the date when the speed attained for Makarov 2, 3 and 5 have two years. Tech was pushed back by a while in 2071 due to a rogue AI-powered FTL capable probe developed by the alien race that this sci-fi plot discusses. The whole plot is set on an alien world named Xanadu, 4.8 quadrillion kilometers (3 quadrillion miles) from Earth. Makarov 5 was achieved in late 2062 (after graviton displacement was accidentally discovered in 2060), but it would take until 2180s when interstellar FTL became legal for development of drives that can go faster than 100 c again.

Don't ask me about how the graviton drive was discovered. In 2060, a dark matter nebula interacted with the force fields of a slower-than-light interstellar spacecraft built in 2057 heading to the Hesal B star system around 19.8 trillion km (13 trillion miles) away from Xanadu, which caused the artificial gravity generator to become off balance, leading to a gradient in graviton strength, allowing the ship to go +2% faster than light. The ship's quantum computer then used that info on the return journey to learn how to manipulate the gradient of the artificial gravity in the front and rear of the ship to create a massive graviton distortion, allowing travel at a little over Makarov 5.2 (196 times the speed of light). The ship even 3d-printed a Muon Decay Catalyzer to allow for a stable graviton displacement field at speeds above Makarov 4.

Muon Decay Catalyzers were kept under wraps until the 25th-26th centuries, as the Xanadu government was afraid that ships could get too fast, and AI designed graviton displacement drives could be used on rogue robotic ships to invade other planets. In other words, AI went rogue in 2071 on Xanadu, and the planet's government could not take any chances with high technology until the 2500s.

I've played a few space games so the fictional technical jargon is familiar somehow.

It makes sense letting an AI do the calculations since humans aren't really built that way.

Yeah, it does. Actually, this plot deals with the Xanadu race, which are gray-skinned hominoids. But yes, the aliens use graviton displacement drives, and the ships are AI-powered, though manual control can be used, but is rarely used. Other ships are partially manual, and need the course and speeds manually plotted out. Others are fully automated, and can calculate the best course and speeds.

Which space game(s) did you play?

The Outer Worlds and Rebel Galaxy come to mind, I can't remember the name of that longer to play game with actual research in it tho.

I should watch some gameplay of those games on YouTube. Sci-fi is fascinating stuff, even if I do not really play video games that much.

Agreed. I'd rather spend that time watching sci-fi, trying to hang out with my friends, or most importantly, making devotionals. Now, if only I can get myself to write a short story involving the Xanadu and the Graviton Displacement Drive. But, I need to set up lore and history for the Xanadu alien race in the Hesal A system, starting with 1909, and then moving on to 2062. Then, in 2570s, the Xanadu decide to visit Earth.

Create an elaborate enough story line, and maybe you can sell it to someone making a show. Good way to influence for the good.

Alright, so we know that it is taboo in Star Trek to use warp drive near planets, so a similar rule must be in place for graviton displacement drives, cos we do not want gravitons interfering with artificial satellites in orbit around the planet(s), or risk crashing into any planets or asteroids. Of course, someone is gonna tell me that the spacing between asteroids is so large, the probability of crashing into one is pretty much zero.

LocationSpeed Limit
Below geosynchronous orbit0.0001 c (67,000 mph)
Between planet and moon(s) above geosynchronous orbitMakarov 0.1 (roughly a few percent the speed of light)
Beyond moon(s) orbits in the inner planetary systemMakarov 1.5 (roughly 2x speed of light)
Outer planetary systemMakarov 3 (12x speed of light)
Beyond inner Kuiper beltMakarov 6.5 (~930x speed of light) until the 25th century,
Makarov 11 (~249,000x speed of light) until further notice.

I thought it was so the space folding technology didn't disrupt the atmosphere causing colonists to suffocate.
Well, in Star Trek, that is partially because of the atmosphere, but mainly to avoid accidents. In my sci-fi plot, low speeds are required to avoid damaging satellites, or if the navigation system failed, allow time for the ship to drop to a standstill or a slow enough speed before colliding with a planet. Also, in my sci-fi plot, it would be better to make sure that spacecraft artificial intelligence knows to not aim directly at a planet, but instead aim to enter an orbit of a few thousand miles above the planet's surface first, cos if the ship systems failed, then the ship would collide with the planet. I'd rather have a ship overshoot and fly by the destination, instead of crash onto a planet.

According to a fan website named after the Star Trek Daystrom Institute, warp drive is not used in solar systems to avoid sucking in debris, or to avoid colliding with other objects.

If a Star Trek warp drive was possible and if it failed, it may produce gravitational waves:

Ooh, one more thing guys: Freighters. Every good sci-fi needs a freighter. However, once a freighter gets old, past the useful lifespan of say 20-40 years, then, either the freight ship has to be recycled, or maybe refurbished and used for another purpose. Say the planet Xanadu has multiple countries. Some countries do not have good space programs, so if one country has a good space program, that country could donate its old ships to a country that lacks a space program.

One freighter, the Yanara (dumb placeholder name) could be retired after years of service from the 2090s to the 2130s. It could then be used by another country to explore the nearby star systems. As freighters in the 2090s were slow, that means the ship would take about a month or two to travel a single light-year at maximum cruise speed of Makorov 2.75 (around 5.9 billion mph). That is abysmally slow. However, as faster-than-light technology was pushed back by a few decades, slow speeds would make sense. It would not be until the early 23rd century that spacecraft would be faster.

Why does my sci-fi need freighters, if the Xa'na race on Xanadu have the technology to make stuff on demand? The Molecular Additive Manufacturing Unit (MAMU) technology invented in 2041 can rearrange molecules and turn thin air into anything for free (rendering the planet's system of currency obsolete), such as food, tools, or medicine, or even heal cancers. The machine works by using miniature electromagnetic tractor beams to latch onto protons and atoms. This comes at a price, as the MAMU uses about 150-400 kWh of electricity per kilogram of matter materialized or transformed.

The reason why the Xanadu still use freighters is because the MAMU uses a ton of electricity. If a freighter is fully packed and uses an efficient fusion reactor and graviton drive, it could use 2x to 10x less energy compared to a MAMU per mass unit of freight. Freighters must also be used in areas where electricity is not abundant, such as shipping freight to space stations that are not connected to the grid. Solar panels could operate MAMUs on space stations, but would not provide enough energy to generate a ton of items besides food for station inhabitants and basic tools.

Guys, what would be a reasonable speed for traveling between star systems?

For myself, I think a speed around Makarov 5 would be the bare minimum for nearby systems (under 20 light-years from Xanadu), or Makarov 7 for farther systems (under 500 light-years). So, if it takes the Xa'na race hundreds of years for tech to increase for ships to travel at Makarov 7 in the 25th and 26th centuries, then the civilization would be stuck with routine travel between closer star systems instead of farther away star systems.

One would have to say, that waiting three centuries to only go up by two increments on a faster-than-light (FTL) scale is a form of technological stagnation. For instance, if a certain component of the graviton displacement drive technology is banned such as the Muon Decay Catalyzer, then the Xa'na would have to improvise and come up with a graviton displacement drive that emits less muons from the get-go.

In the Star Trek universe, once the Federation had higher warp speed capabilities, the Federation expanded. So, one could assume for my sci-fi plot, once the Xa'na have higher Makarov speed capabilities, more opportunities open up for alliances between different species.
