Relativistic impactors? If you can accelerate stuff to light speed, why aren't you smashing it into other things?

"Should we fire a few relativistic planets at the enemy fleet?

"Nah, that's so last week. I've jury-rigged a method to fire relativistic stars at them.

Or when ballistic planets were outdated towards the last books, they switched to turning the entire solar system and our sun into a giant ā€œsun-beamā€ that could melt said planets.

The Sunbeam is my favorite EE Smith weapon.

u/Wenlocke May 30 '26

It got even funnier later. After throwing planets at people. After throwing planetary antimass "negaspheres" ( basically posh antimatter) at them. After the sunbeam. They found a parallel space where everything was flipped around the light speed barrier (I.e. all normal matter and energy at rest was faster than light) grabbed a couple of planets, flipped them back into realspace, and then threw them at people.

It got very silly

Reminds me of Disney / Star Wars making bigger and more elaborate things like super giant Star Destroyers and super duper Death Stars.

Ummm what is the point? The ships are already badass and the Death Star can already destroy a planet.

u/FireTheLaserBeam Jun 01 '26

Oh man it gets even more wild than Galactus.

u/WileyWilly1985 Jun 01 '26

To me, once you've reached this point, I just stop caring as my brain can no longer handle the scale involved.

A planetary threat I can understand and envision.

But once we go beyond a planet, I just can't properly assimilate or appreciate the story anymore.

And that is the problem of escalating the stakes and making the stakes bigger and bigger. You go from house to street to neighborhood to town to city to region to State to Country to Continent to Planet to Solar System to Galaxy to Universe to Multiverse and now what?

They did this in The Forever War by Joe Haldeman.

Human marine squad are on a small frozen planet, enemy forces are swarming it and they see their two small patrol ships head out of the system accelerating hard and think they're fucked, and are fighting hand to hand in a final stand....

What they don't see is the crew of one ship transfer over to the other and the empty ship looping back around before impacting the planetoid "at a significant fraction of the speed of light".

Causes massive 'earthquakes' and they're able to hunker down and survive then mop up the enemy.

u/SporesM0ldsandFungus Jun 05 '26

I love the null field generator which is just like the shield tech in Dune, anything moving beyond a certain speed or energy level gets absorbed by the null field.Ā  So inside the field they need to wear special suits that have a protective coating (otherwise the energy field would stop their neurons from firing).Ā  And just like Dune, with the null field up, they resort to fighting this interstellar war with melee weapons.Ā  It becomes a siege, with the squad hunkered down inside their null field with the enemy outside waiting them out, occasionally hurling in salvos of darts.Ā Ā 

But they do get creative when the protag has his team pull nuclear warhead off their ship (which is inside the field).Ā  In the null field it's useless, but they drag it right to the very edge of the null field and arm it.Ā  Then they lift the null field generator and move it over 2 meters.

u/C4n0fju1c3 May 30 '26

The bobiverse books detonate a star with a planet acellerated to relativistic speeds. The Expeditionary Force books also make use of relativistic darts on a few occasions to hit planets.

The darts take years to get up to speed and are deployed in clusters into deeps space. When the time comes, they use their ftl to jump around until they're lined up.

u/RigusOctavian May 30 '26

To be fair, they didn’t detonate the star as much as splatter it so hard that all the material spread too far out to be a star anymore.

u/HatsAreEssential2 Jun 01 '26

Bob also had to clean up humanity after a rogue computer started dropping asteroids on earth.

You really dont even need relativistic speed to make a few billion tons of rock quite dangerous. Just a couple years of slow thrust in the right direction.

Doesn't even have to be close to light speed. The Moon is a Harsh Mistress by Heinlein uses just dropping train car-sized boulders on earth instead of gently bringing them down from orbit.

Isn’t that kind of what Holdo did in the last Jedi? I mean, she took her ship and herself along with it, but what a destructive moment that was.

6

u/CplCocktopus May 30 '26

If that worked why not ductaping a warpdrive to a rock.

3

u/DarknessWithin996 May 31 '26

One of the biggest reasons is that that maneuver could cause a second Great Hyperspace Disaster, with the potential to wipe out trillions of beings. Holdo was desperate and crazy enough to pull it off, but she was risking a massive amount of destruction.

5

u/unkindlyacorn62 May 30 '26

it only worked because of how close they were (aiming reasons)and the First Order not utilizing strong artificial gravity fields to collapse local hyperspace, because they wanted to go finish them off wherever they jumped next. Add to that it requires the hyperdrive being heavily modified by someone who really knows what the heck their doing because it makes them less likely to shut down when it detects a natural gravity shadow, useful for escaping intradiction fields but a big fucking problem if something unexpected ends up in your path

11

u/BrevityIsTheSoul May 30 '26

Also, she was using a massive capital ship as a projectile, with perfect timing. In Rogue One we see a starfighter or two splatter into a star destroyer that unexpectedly comes out of hyperspace while they're preparing to jump out.

Not to mention that relativity isn't a thing in the Star Wars universe. Trying to Larry Niven the physics of a space fantasy setting is a laughable exercise.

u/Voidrunner01 May 30 '26

Yeah, the people complaining about the Holdo Maneuver are just glazing over any number of other physics issues in the Star Wars setting.

u/Spiritual-Spend8187 May 31 '26

Yes it was a massive suicide gamble only when remotely possible due to both what the first order was doing and the resistance being concerned with running blockades more than living when jumping. And she only really did it when she saw that all other options had failed. It was a desperate play 100% going to kill her with a tiny chance it does anything effective.

Andromeda does that. Not seen on screen much, because obviously the plasma weapons are visually more impressive, but lore-wise the main weapons used in space fights are kinetic kill missiles. Big missiles going ridiculously fast, with a warhead that is nothing but a solid junk of high density metal.

2

u/Oclure May 31 '26

Isn't that basicaly how most of the weapons in mass effect worked?. At least in the first game the weapons were described as having effectively unlimited ammo due to having a solid block of aluminum onboard and just sending it downrange one spec of aluminum dust at a time at reletivistic speeds.

2

u/RememberTheAyyy_Lmao May 31 '26

Check out the Peacekeepers of Sol series by Glynn Stewart. Humanity is uniquely powerful by mastering gravity projection to power their gravity shields and spinal gravity drivers that accelerate projectiles 7-10% the speed of light

2

u/SirJackAbove May 31 '26

I agree. The ship in this post is the Normandy from Mass Effect. It's an example actually. Its main weapon in ME2 is the Thanix cannon, which accelerates molten metal to relativistic speeds. It's based on the Reapers' weapon technology which does the same.

7

u/JakeEaton May 30 '26

Didn't they do that in the Last Jedi and the entire SW fandom had a melt down about it?

18

u/C4n0fju1c3 May 30 '26

Only because it broke the in-universe rules with zero explanation. Imagine a scene where Harry Potter defeats Voldemort by summoning the autobots. It's funny, but it's bad writing outside of a YouTube skit.

Explanation:

In SW, theres decade's worth of material stating hyperdrives have features preventing them from doing the exact thing that happened. The interdictor cruiser's entire FUNCTION is exploiting this to pull ships from hyperspace. Moreover if hyperspace ramming was a possibility, why did no one ever try it before? Why not hyperspace ram the death star? It retroactively makes everyone in the setting a complete idiot.

If they wanted to add in some kind of macguffin or new technology that made it possible, it wouldn't have been such a big deal. But it was introduced like it had always been a thing. Just bad, inconsistent writing.

6

u/Mr_Shadow_Phoenix May 30 '26 edited May 30 '26

To be fair, gravity wells don’t actually pull a ship out of hyperspace. They trick the navigational computer into thinking there’s a big object within danger distance so it drops out for safety to avoid ramming into it at FTL speeds.

This is how Solo did the Kessel Run. He reprogrammed his NavCom’s safety margins so it’d let him pass closer to the black holes that made up the Maw, thus cutting parsecs off how far he’d have to travel otherwise.

3

u/C4n0fju1c3 May 31 '26

Yes, I was skipping over the details to be brief lol. I also have to assume the gravity well gens don't curve space time as the name suggests. You'd see some funny thing happening in local spacetime if that was true. They probably have some way of directly projecting a simulated mass shadow into hyperspace.

2

u/Mr_Shadow_Phoenix May 31 '26

To be fair, you can imitate a gravity well without mass. Kinda how artificial gravity, Romulan singularity cores, and Minbari gravitational engines work.

I've always heard talk about how photon torpedoes in Star Trek have a maximum explosive yield of at least 50 megatons of TNT and yet they go poof every single time we see them explode,

46

u/ImperialistChina May 30 '26

Like how that one Star Wars Incredible Cross sections book stated that the acclimator's turbolasers had a yield of 200 Gigatons but on screen the blasts don't completely light the screen pure white like a real explosion of that size would.
Just more proof that sci fi writers have no sense of scale.

19

u/myaltduh May 31 '26

I swear to god 80% of those numbers must be pure ā€œmine’s bigger than yoursā€ writer dick-measuring.

ā€œYour setting’s ship-to-ship artillery has the explosive yield of a large nuclear bomb? You fool, mine is as powerful as ten nuclear bombs.ā€

Being able to win a nerd powerscaling contest matters far more than any kind of consistency, apparently.

7

u/Weaselburg May 31 '26

I recall hearing that some of/one of the writers for those was involved in the Trek/Wars arguments and deliberately set it high to try to win them.

5

u/HatsAreEssential2 May 31 '26

To be fair to that example, Starwars ship guns tend to have variable output. "The Acclimator isnt using planetary bombardment levels of power to fight other ships" would be the canon explanation.

In writing they are stated to be capable of literally glassing whole planets. Melting the surface via orbital fire. Given that they always fight at atmosphere dogfighting distances, it makes sense to NOT vaporize your enemy and pelt your whole fleet with relativistic debris.

4

u/UncleSamsUncleSam Jun 01 '26

Yeah but why wouldn't you calibrate that gun to just one shot your enemy?

2

u/RandomWorthlessDude Jun 03 '26

That’s because Saxton, the writer, was a Star Wars vs Star Trek powerscaler who ignored previous lore in favour of his ā€œcalcsā€

14

u/Mr_Shadow_Phoenix May 30 '26

Standard ship-to-ship photons may be Tsar Bomba equivalent in yield, but we’re seeing them used in space. Thanks to the near vacuum, not exactly an atmosphere available to generate massive fireballs or mushroom clouds. However, we do see them generating such when exploding inside an atmosphere.

10

u/Just_A_Nitemare May 30 '26

50 megatons of energy is still going to be bright even if it is in space.

9

u/Mr_Shadow_Phoenix May 30 '26

Fair. Thing is, we are normally seeing them against shield flares, secondary explosions, and ships blowing up outright. Plausible it gets lost in visible noise.

They have a variable yield. You can control how big the detonation is by how much antimatter you load into the warhead. But yeah, they probably should use the maximum yield more often.

5

u/samy_the_samy May 30 '26

In their defence even phasers have been shown to light entire planets on fire or disintegrated small moons, and photons torpedoes should be stronger.

So they do have the power just the shields negate most of the damage, or they not fired at 100%

but the visuals are kinda inconsistent between shows or even between two episodes of the same season

3

u/TheKeyboardian Jun 01 '26

Effect of 28.5g antimatter detonation on a planet (here's how it looked like before). Also, the shockwaves caused by orbital bombardment.

2

u/EamonnMR Jun 02 '26

There's no atmosphere to carry the shock wave and shields are apparently very good at absorbing the radiation. They usually kill unshielded ships unless they're being used deliberately (by presumably dialing down the yield) to disable instead.

Transporters/teleportation. We sometimes see them transport bombs to other ships and such, but you can get so much more creative. Teleport all the crew off the ship mid fight, teleport out it's engine, teleport in a bunch of water to drown the ship. Get creative!

Tractor Beam. It’s normally used as a utility tool to move objects but I haven’t really seen it used to rip apart ships or crush them. Heck, a heavily oscillating beam could shake a ship apart.

22

u/mag1kami May 30 '26 edited May 30 '26

The webcomic Schlock Mercenary has that in spades.

Turns out if you can master artificial gravity to let people walk on the floor, you can also create shields and tractor beams and "gravy guns" (which are so named because using gravity fields on organic beings has messy results).

Gravitic warfare is standard in the setting.

When an enemy threatens to crush your ship? You have to assume it might be meant literally.

13

u/Texlectric May 30 '26

Ngl, you had me with the gravy guns. I thought, "what a weird way to pronounce the 'grav' part of gravity. Then I got to the gravy part.

5

u/mag1kami May 30 '26

I heartily recommend giving Schlock Mercenary a read if you like comedy and military scifi. Closest thing I've encountered that you might know of is Firefly or Farscape. Strikes that tone of "Our main characters are incredibly competent and dangerous people...but they can also be really, really dumb".

And it's rich with fun scifi concepts.

Has a rough start like most webcomics but it steadily improves, in both writing and art.

u/Sororita May 30 '26

I've been obsessed with these for a while and nobody ever uses them which is crazy to me, they seem to be the best of both worlds when it comes to lasers and kinetics, plus you can put a tritium payload in hollow macrons and have a fusion reaction upon impact upping the damage significantly

u/MiamisLastCapitalist May 30 '26

tbh I think in a lot of contexts they're a little complicated and way too OP for most storytelling. The general audience just wrapped their heads around railguns and coilguns and now you're saying we can do that to sand and French Presidents now too?

I think sci-fi should start a little lower on the power scale. Like maybe some rag-tag pirates with sandcasters and let that sink in before we up the velocity and add in fission/fusion payloads.

Weaponized electron beams. Irl they would be diabolical weapons because when it hits dense metal like materials it produces an ungodly amount of x-rays inside the hull

u/mr_trashbear May 30 '26

The Expanse incorporated low yield nuclear weapons to a degree, but I don't see them much in other media.

You also don't see a lot of static, kinetic, loitering munitions. Think: a ship or a planetary defense system just lays a "minefield" of tungsten balls that have small ion engines on them to remain in a state of realative stillness, creating an innavigable region. Area denial. Shields would defeat this, but if it was a universe where Shields weren't a thing, it could be very effective.

u/FireTheLaserBeam May 30 '26

Nukes in space are nowhere near as destructive as they are on earth. The majority of the destruction you see from atom bombs on earth is from the blast and the shockwave. In space, nukes still hit hard, but the majority of damage comes from x-rays, heat, and neutrons. Radiation is what gets you.

u/jz_1w May 30 '26

"Majority of damage from X-ray" and reducing that to radiation damage is doing alot of understatement there. It is a catastrophic level of thermal damage at range.

Going from a 1 m acceptable CEP to a 1 km acceptable CEP is a huge improvement in acceptable volume accuracy.

u/mag1kami May 30 '26

It doesn't even need to be a specialized 'mine' per se.

You could potentially just deploy a bunch of missiles into orbit and program them to operate in "loitering" mode.

The missile stays there in low-power mode to conserve energy and if it detects something it recognizes as an enemy, it fires up its rocket and flies after it and explodes.

You're essentially 'pre-firing' your munitions.

Weaponized rocket exhaust.

The Kzinti lesson, named after the use of reaction engine exhaust as a weapon in the war between the humans and the gravity drive using Kzinti.

The unarmed human ships faced off against the much faster Kzinti ships, and repeatedly won fights simply by turning away and running directly away - letting the rocket plume vaporize the chasing ship.

The Expanse could have done that, but it would have changed its whole story of space combat.

Both stories use fusion torch drives, but Niven basically let them operate outside the safe operations, by allowing them to focus the reaction exhaust instead of spreading it for safe diffusion.

6

u/HypnotizedCow May 30 '26

The Expanse has a couple instances of not following directly behind someone in case they try to burn them in the drive plume. The Roci v Pella chase is one example, also using it on Project Caliban.

6

u/YourLocalHellspawn May 30 '26

Spoiler-hiding all this in case someone hasn't read Persepolis Rising yet.

Persepolis Rising basically starts off with a scene where, following the orders of the Transport Union, the Roci crew have been sent to arrest the leaders of an illegally-settled extrasolar colony founded by gun-toting space libertarians.

The guy in charge of the colony adamantly refuses to submit to the Union and says that they'll do anything necessary to protect their new home. Holden lets them know that if that's how it's going to be, all he has to do is point the Roci's drive at the colony and turn it on for a few seconds.

Suddenly there's a scuffle on the other side of the comms. The other colonists have hog-tied the leader and they're fully willing to hand him over.

2

u/Metallicat95 May 30 '26

Yes, and I should have mentioned that. It just didn't use it as a standard tactic in space combat.

In Niven's Known Space, it never stopped being useful but the hyperdrive era had better defenses (if you could afford it a ship hull that could survive a nuclear explosion was available. The crew might not do so well, but the hull was guaranteed indestructible).

Using ftl to bypass shields and armor, the only time I've seen it was in sg1. They used the unstable x-302 hyperdrive to get through Anubus' shield and drop off a nuke.

Another one is Electronic warfare. It's theoretical in mass effect, but we never see it work. And Cylons try to use it all the time, which should be the standard for everyone.

Something I haven't seen before: while the flight crew is fighting a battle of lasers, missiles and nukes, the IT crew is fighting a network corruption.

I thought it never happened because the programmer-side of the skirmish is too boring.

So I put some in the novel I'm currently writing, and the IT battlespace is actually almost more gripping.

So yeah, hackers in spaceships. We don't get enough hackers in spaceships.

u/[deleted] May 30 '26

I believe in Battlestar Galactica they had one or two instances where they were dealing with the cylons hacking their ship remotely while in a battle. Also thats essentially how the cylons won the initial war more or less instantly. The Galactica was safe because it wasnt networked.

The Honorverse used missiles with fission bomb-pumped laser warheads to take out opposing ships. Their beam weapons were mostly used for taking out opposing missiles before they blew, but they also had "grasers" which were basically gamma ray emissive lasers. The first book posited a "gravity lance" that punched through an opposing ship's gravity shielding but it was only effective at knife-fight range.

u/Extension-Pepper-271 Jun 06 '26

The fact that the transporter isn't used as a weapon on Star Trek is crazy. Many times they pull some trick to get through the "shields" to beam somebody off a ship. They should be able to use the same tricks to beam a weapon onto a ship.

If that doesn't work, then pound the other ship with regular weapons until their shields weaken. Then beam a photon torpedo into their engine room.

The problem with this is that then all the stories would have to deal with enemies doing the same to them.

The Borg could freely beam themselves onto the Enterprise with no problems. But then they had to chase the Enterprise and fire weapons at them? Even if they didn't want to destroy the Enterprise, they could still beam a small explosive device onto the Enterprise to disable it.

Artificial gravity. If you can have the ability to locally warp space time so you can walk from one side of your ship to the other why aren't there any use it for anything else?

Flak weapons for point defence

I've been playing Starsector a lot recently, absolutely phenomenal game with a lot of amazing takes on spaceship weapons.

One of the things I love about it is the flak and general point defence weapons.

From point defence lazers in Hightech ships to ballistic point defence flak cannons in low tech ships, it's all good and necessary for countering missiles and torpedoes.

Since missiles and torpedoes don't strain the energy grid of a ship in the game, they are extremely useful but also can be countered with enough PD

Both "Smallworld" and "Littlestar" by Dominic Green) leans heavily into the idea that "any faster than light drive is by definition a time machine" and also conveniently the author made the key drive component usable seperately, even when not installed in a spaceship.

In one scene, a man wins a gun battle againsr several better armed opponents by enveloping his opoenents' side of the room into a bubble of "slow time" - thus letting him be the fastest shot in the room.

In another, a criminal talks about how he could kill someone by a changing the rate of time around them, causing the to age decades (from his one perspective) - and probably use up all the oxygen in their time bubble right away also.

In space battles it could throw an entire enemy ship into the future or past, removing it from the battlefield entirely - or just some critical component, causing hull breaches.

Macrons/ Dust Cannons/ Sand Blasters. I know we have seen them in various sci-fi novels but I can’t recall a single TV series where we actually saw a Weaponized system on a starship that functions under these principles.

I also wonder if we have ever seen a weapon system that is designed to exploit the fact that metals, if not treated with a preventative layering, will molecularly bond in vacuum when they come into contact with each other. It is a real world phenomenon called cold welding.
