Talk:Magnetic Accelerator Cannon

MAC Yields and Realism

I just want to throw this out there since the talk page seems to be centered around the power of this weapon: none of the figures that have been calculated can be possible, and I doubt the authors of the novels or the encyclopedia considered logic too terribly much when they wrote them, thus they simply made up figures that sounded cool. Here's why 1.17 teratons is completely retarded and unrealistic: the covenant supercruiser of FoR took 3 MAC hits to its shield, and it didn't fail. That would be equal to 1.17*3=3.51 teratons of kinetic energy dissipated. The largest nuclear weapon ever detonated was the Tsar Bomba in 1961, at 50 megatons. Thus, the supercruiser's shield should have absorbed over 70000 times the energy of the world's most powerful nuclear weapon, which itself had a power output of 1.4% of the sun. If covenant ships can generate that much power, then one of them should be able to obliterate the planet (exaggeration, yes, just making a hyperbole here). HORNET mines, as seen in GoO, can destroy a fleet of covenant vessels, yet they are but a mere 30 megatons of yield. How is this possible? Because the MAC is not nearly as powerful as is asserted on this page. We know that covenant vessels can survive nuclear blasts in the multimegaton range undamaged, but as a nuclear detonation in space spreads its energy out spherically from the point of detonation, a comparatively tiny fraction of the energy is going to hit any given ship, even at point blank. Those who have asserted powers in the several kilotons are likely the most accurate in regard to the MAC power, given what we know about nuclear weapons vs covenant shields. And the power of the super MACS? All recharged in 5 seconds? Don't even get me started on the rediculous nature of THAT.... Quakeomaniac 08:40, January 7, 2010 (UTC)

This is Sci-fi, get use to it.
Non of the figures calculated can be possible? Its sci-fi and canon overrides all else.
Lie, the shields of the super cruiser were downed by MAC 3 MAC rounds and around 500 Archer missiles.
GoO is overruled by the latest canon info, the Halo Encyclopedia. Per Bungies canon policy old overrules old so older sources can not be used to overrule it.
Farther on Nukes: The UNSC NOVA Bomb is proof that the UNSC has Teraton range nuclear devices given that it is stated to be nine fusion warheads with yield increased a hundredfold which means each warhead is 1/900th of the low-end 1.2 Petatons!

If Megaton range weapons were able to be used why then would the UNSC not nuke spam the Covenant with the resources needed for one NOVA Bomb?

Ah, trying to dispute a state canon fact that the SMACs per TFoR can fire every 5 seconds?
This is sci-fi, watch Star Trek if you really want to see impossible stuff.—This unsigned comment was made by 207.200.116.136 (talk • contribs). Please sign your posts with ~~~~

Quakeomaniac does have a point, if not to point out the inconsistencies of Halo. The Covenant shields do seem to possess different outputs and strengths, as many different weapons of different yields can be used to tear through their shields. A teraton range does seem unrealistic if a megaton warhead is enough. I would think that ships armed with MACs would have little trouble against Covenant ships. Aiming would be the hardest part. Can you be more clear on your 1.2 Petaton assertion? That seems like an AWFULLY large yield for a mere nine warheads, even if they are fusion.

As for Star Trek, yes the stuff is impossible, but the creators hired scientists, physicists, and other experts in the field to literally invent futuristic devices, sights, concepts, and technology that was not only futuristic and cool, but also scientifically possible, meaning we as the modern human race could produce it or find it given the proper resources. Everything on that show is something that could theoretically exist (can't speak for the new movie). File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 14:46, January 7, 2010 (UTC)

I appreciate you taking the time to consider what I said Orion rather than just call me an idiot with a bunch of nonsense. Regarding the inconsistencies, here's an interesting one. The page for the covenant carrier states it can withstand 3 MAC rounds (not sure where that comes from, I'll just take it for now). Yet, the supercruiser in TFoR also took 3 MACs and a bit more (the archers) to drop its own shields. This implies that the carrier and supercruiser, two drastically different sized ships, have roughly equal shields. Makes little sense. This could perhaps be rectified if we knew the yield of an archer missile relative to a MAC round, but we assume its low based on the book. As for the guy who doesn't bother to sign his comments: Yes, this is sci-fi, thank you captain obvious. This does not prevent a meaningful discussion of it. As far as canon, that's the whole point I'm making, nothing agrees. As for the supercruiser, can you tell me where I mentioned the archer missile part? The GoO assertation doesn't need comment. Also the NOVA bomb is nowhere near a normal nuke, and the technology used in it is NOT used in the reactors on ships, which is what powers the MAC. And I'm not trying to state the SMAC can't fire every five seconds, merely that its energy usasage (if it's a 9+ teraton shot) is unrealistically enormous. Anyway, please consider what I said and try to have a meaningful discussion on it rather than insult me. Quakeomaniac 18:19, January 7, 2010 (UTC)

No problem. I understand how these things are. Jumping the gun and rushing to false conclusions only makes hot heads and steeled tempers, so the whole debate turns into an honor fight or resembles two brick walls communicating with each other. I definitely see the inconsistencies with shielding here. Perhaps the supercruiser was already suffering from decreased shield output so it took less force to breach them?

Based on the Archer's specifications and relative 'advancement' of human warfare technology and such, I would say the Archer has a pretty low yield, at least when compared to a MAC. But there could be some other factor in here not mentioned already: chemistry. Perhaps the chemical properties of the various warheads and MAC rounds create different situations for the Covenant shielding, so a nuclear warhead could deal more damage to a shield simply because its reacting causes additional strain on the shield. Conversely, the MAC could cause some chemistry to weaken the shielding, dealing more damage than other firepower.

By the way, if you are familiar with the Romluan Warbird (pretty sure that's it), its most destructive weapon is somewhere on the order of a 52 terawatt beam. Now I don't know how that stacks up to a 1.17 teraton blast yield, but the Warbird is MASSIVE and I would suspect it is because it needs so much machinery to sustain a beam of that wattage. Just throwing it out there. As such, I am led to believe that the propensity for a ship the size of the POA using a single weapon with a 9+ teraton yield, considering how the most powerful nuke ever devised doesn't even begin to compare, is very, very low. A teraton output seems out of proportions, considering how in the 26th century, humanity still drives on wheels and still fires metal at supersonic speeds as their primary weaponry. Sure other advances have been made, but I would think that if we have AI that are practically sentient then we should have more phaser-like technology and hovercars.

PS: don't forget to watch your capitalization. Covenant should be capitalized. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 18:41, January 7, 2010 (UTC)

I am familiar with the Romulan ship, presumably you refer to the D'deridex class warbirds, which are, at least based on the designer's intentions, approximately 1300 meters long, larger than most any UNSC ship, slightly smaller than a Covenant destroyer. Fifty-two terawatts is nowhere even CLOSE to 1.17 teratons, as the Tsar Bomba was 5.4 YOTTAWATTS in power output (for reference, tera is 10^12, yotta is 10^24). So there we have it, technology in Trek is far more advanced, yet somehow the halo weapons are tremendously more powerful? I think we can conclude that the MAC yield is improbable. Quakeomaniac 18:54, January 7, 2010 (UTC)

Also, your idea about chemistry is rather interesting. I always looked at energy shields in any universe as just an energy vs energy concept. In halo though, we see plasma weapons doing more damage to shields, and your reasoning of chemistry (could be physics too), makes sense to account for the difference. If you have any more thoughts on chemistry and shields, please toss them out there. I don't know that chemistry can account for a huge huge difference in nuclear and MAC yield, but it could be helpful nonetheless. Quakeomaniac 19:06, January 7, 2010 (UTC)

I used to see shielding as energy vs. energy, or rather a form of energy that was 'solidified' to withstand/absorb other forms of energy on impact. As such, I viewed a shield as a simple solid geometric plane encapsulating a vessel, and was neither penetrable nor malleable. However, hearing how the Covenant shielding was penetrated in a specific area, and recounting various other accounts of buckling shielding and whatnot, my outlook on the standard model of vessel-based shielding has changed. Perhaps the shielding is generated by oscillating specific frequencies around the ship. These frequencies could interact with various types of energy to produce a shielding effect by either neutralizing the incoming energy, or reducing its bite. This setup could potentially allow for many different things to enter an exit the space surrounding a vessel freely, while at the same time blocking damaging energy. If this is the case, then chemistry is more than likely a major component in shield design.

We see that MJOLNIR shields are easily depleted by sustained plasma fire, and a charged plasma pistol shot wipes them out, no matter how strong. This definitely implies some chemical workings here. For an overcharged shot to completely neutralize an overshield, yet have a much smaller effect as a single shot means that the shields could be overloaded by a high amount of plasma impacting at one moment. This could have some chemical interaction between the shields and plasma. My theory is that shields can neutralize as small amount of incoming plasma, but still allow some of it to reduce the shield integrity. If too much plasma impacts at one moment, then the shield cannot neutralize enough for the plasma to overwhelm the integrity and collapse it.

Now that is not chemistry right there, but chemical interaction could easily occur between the shields (or energy frequencies) and, say, a NOVA bomb. I believe that a MAC round, being a pure kinetic weapon, does not interact with the Covenant shielding in any way other than busting through it. If anything, the speed of the round could create some as-of-yet undiscovered (or unmentioned) form energy to collect up, similar to how a bullet bunches up the air in front of it as it travels. As this bunching of energy nears the shields, it could cause the frequencies or shielding to thin out (or likewise thicken up). A NOVA bomb could work in the same way, and could also create interactions by detonating. The nuclear blast and radiation could interact with the shielding in a detrimental way.

And as if all that wasn't enough, it may also be possible that the shielding only stops more conventional forms of energy, i.e. kinetic, nuclear, light, etc., but may actually act as a semipermeable membrane and allow other forms of energy, possibly those generated form a NOVA blast, to pass through. These forms of energy could interact with whatever it is that produces the shielding and corrupt their integrity.

Whew, this is fun. Lots of stuff to consider when one examines an event analytically and scientifically haha. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 20:25, January 7, 2010 (UTC)

Hah, yeah you make a great point here, I also enjoy looking at a fictional technology in a scientific way. Who knows, could tell us how it works one day. Interesting though how we went more from a MAC discussion to a shield/star trek (what with the frequencies) discussion though, but it's no problem. I was looking at the energy shield talk page earlier, and RelentlessRecusant posted a neat bit on shield physics, and he made some points that are similar to what you're saying. Would be nice to get him to read over this discussion. You can flip over to that and read it real quick if you want, tell me what you think. The concept on plasma pistols makes good sense, as does the idea of allowing some things (i.e EM energy from shipboard sensors) to pass freely in and out of the shield, while damaging energy (i.e the ships plasma torpedoes) can't, as we see it drop parts of the shield to fire. I can't disagree with what you've said, as it sounds good, and I like the thought in it. Quakeomaniac 21:04, January 7, 2010 (UTC)

Will check it out. However, the overall values of MAC yields still remain unsolved. I did see that they were changed to the gigaton level again, which is more reasonable but perhaps too high. I would need more specific examples of MAC and NOVAs being used in combat to formulate a working hypothesis, as I have not read any of the books (wish I owned them). File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 22:40, January 7, 2010 (UTC)

Definitely recommend reading the books, they're great. Haven't read them all myself, but I have read the Nylund novels. I would concur that a gigaton range is still quite a bit too high. I personally feel that anything higher than the very low megaton range is too much, because I'm using HORNET mines as my estimate for the upper limit of the typical Covenant ship (essentially anything but the most powerful vessels i.e assault or supercarriers) shields. One nuclear detonation on the scale of 30 megatons, the yield of the mines, will drop, or come close to dropping, the ships' shields. Now, maybe the EMP effect of nuclear detonations has an effect here, but I can't see it being so huge that a MAC would need teratons of energy to compensate for the lack of the EMP effect. Thus, based on the common occurence of two to three MAC shells to break a shield, and the fact that a nuke in space won't direct anywhere near all its energy upon a single ship, I conclude that the likely yield of a MAC is somewhere in the mid to high kiloton range. But as you said, it's an unsolved mystery. Quakeomaniac 03:18, January 8, 2010 (UTC)

After reading your response above, a new theory came to mind. Since a MAC round is purely kinetic, that force could easily be sustained, absorbed, or dispersed, at least somewhat. So my hypothesis is that Covenant shields are able to absorb a significant degree of kinetic energy, but they can only sustain so much. If a MAC round were to possess teratons of kinetic energy, perhaps teratons were absorbed, but a few kilo- or gigatons were leftover, and these penetrated the shields, making a few MAC rounds comparable to NOVA bombs, HORNET mines, and such. This explains why the UNSC would need a weapon with such a high yield, but leaves the question of how unanswered. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 05:32, January 8, 2010 (UTC)

Ok.... I'm not 100% sure I follow you on this one. If I'm reading what you said correctly, you're theorizing that the shield is simply extremely effective against kinetic impact, but against something such as electromagnetic radiation (x-rays and gamma rays and the like) released from a nuclear explosion, they can't withstand it as well? This also makes me wonder, based on this... the book seems to indicate that a vessel's shields are split into multiple sections (as we see both Cortana aboard the Ascendant Justice and 'Mantakree's officers aboard the Incorruptible indicate certain portions of the shield failed), and a MAC round directs maximum energy over minimum surface area, much like modern kinetic energy penetrators fired from tank guns, so that the round would direct all energy upon one portion of the shield. A nuclear explosion would disperse its energy over the entire ship's shields (or at least one side). This even further seems to support that the MAC yield is far lower than the article suggets, but at the same time, it does not refute your theory that the shields are simply very efficient at dispersing kinetic hits, much like an elite's shield is versus human weapons. Actually, nuclear explosions, at least here on Earth, create an ultrahot plasma at their hypocenter, which is seen as the characteristic fireball. Now, in space, a nuclear detonation simply releases an enormous amount of high energy radiation, since there's not an atmosphere to absorb it and create a fireball, BUT, the whole idea of introducing the plasma part in atmospheric detonations is to suggest that, since we know shields to be weak to plasma, nuclear explosions may be much more effective against shields, thus allowing a lesser amount of energy, in a different form, to penetrate them. I apologize for the rambling, but new ideas seem to come up quickly. Quakeomaniac 06:36, January 8, 2010 (UTC)

Hey no worries. I know what it's like. I theorize that the shields are not necessarily extremely effective at dispersing kinetic energy, just capable of dispersing a large amount. If a MAC round really did have teratons of energy, then I theorize a Covenant shield would be incapable of preventing all of that energy from penetrating the shield, leaving a few kilo- or gigatons left over that damage the ship's exterior. The shields could withstand some of the force from a nuclear blast, particularly the rushing wave of particles and energy, but against the radioactive side of things, the shields may not be able to block all or any of it.

Your statement on different sections is definitely interesting. I didn't know that. If the shield is broken up into different powered sections, I would think each section would be stronger overall then just powering a single shield section. This would mean more force can be sustained, and the UNSC would need more force to penetrate. Since plasma energy could be produced via a nuclear explosion in space, and Covenant shielding has been observed to be vulnerable to plasma fire, this could make a NOVA bomb a better weapon of choice against the Covenant, even though it has a small yield. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 14:41, January 8, 2010 (UTC)

Are you suggesting that anytime a MAC round impacts a covenant shield, a small part of the energy makes it through? Like.... that no number of rounds would TOTALLY drop it, but each successive round would do more and more hull damage? Also, the idea of compartmentalized shield sections having more power is a neat idea, as it would allow a shipmaster to divert power to sections of the shield that are vulnerable, and disable sections not in any danger. Quakeomaniac 18:10, January 8, 2010 (UTC)

Not quite. In my mind, shields can only take so much battering before they just become useless. Perhaps they still have some effectiveness, but when you consider the fact that the Covenant is getting their posterior whooped by tungsten slugs traveling at nearly half the speed of light, a weak shield isn't going to do much for them. I believe that after so much MAC impacts the shields fail to stop most, if any, of the MACs kinetic energy, so two or three successive shots could punch a hole by deteriorating a shield section. Speaking of sections, I definitely think they are used, especially in Star Trek. The idea of a uni-shield seems ineffective and weak when compared to the advantages of multi-shielding. Over half this conversation should be moved to the shield talk page methinks haha. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 18:30, January 8, 2010 (UTC)

As for the shield talk page... yeah that would probably be a good idea. Star trek definitely uses sections, in the new movie Pike says "divert auxiliary power from port nacelles to FORWARD shields." I pretty much concur with what you say on shields... now we just need a logical explanation as to HOW the UNSC reactors can produce that much energy, if we're going to go with the why that this enormous conversation created. Quakeomaniac 20:23, January 8, 2010 (UTC)

I agree. I'll get back and see if I can't move this to the shield talk page. Perhaps someone there will know why a MAC round is listed as such a kinetically powerful weapon. I mean really the force should be calculable by Newton's Second Law (F=ma), so if I can get the mass of the slug and the acceleration imparted on it by the magnetic coils. Given the mass is a large, as is the acceleration (they list it as half of c), I would expect the force to me likewise large, but I would need to convert the force units from F=ma (Newtons) to teratons (or gigatons, kilotons, etc). File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 21:36, January 8, 2010 (UTC)

Please continue your discussion below. Oh, avoid using the asterisks (*).- 5əb'7aŋk^(7alk) 21:50, January 8, 2010 (UTC)

My apologies. I knew I was missing something by using *. It was a : instead. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 23:07, January 8, 2010 (UTC)

Please don't take this as an insult, but I'd just like to point out that Newton's second law doesn't mean anything. The physical constant C is a velocity, approximately 3*10^8 meters per second, not an acceleration. The formula you are looking for is that for kinetic energy, E=(1/2)MV^2. By the work-kinetic energy theorem, this formula will account for the forces imparted by the slug anyway. Force and energy (kilotons, megatons, so on are units of energy) are not the same thing, so you can't convert them directly. Just trying to steer you in the right direction. Quakeomaniac 22:28, January 8, 2010 (UTC)

None taken. I forgot that one. I wasn't saying c was the acceleration, just the speed to which the slug is accelerated to. The actual acceleration could be calculated by a=v/t and should be a fairly simple matter. I have never worked with the -ton units before, so I assumed they were force units. However, I have no idea how I arrived at that, considering how this whole discussion has been about energy. But yes, the ΔKE equation will work. Since we need the energy value, I just realized we have no use for the acceleration but to calculate the force as an added bonus. UNLESS...the Covenant shields protect against energy and force, in which case it could be difficult to discern which of the two properties the MAC slug uses to breach the shields. This could mean that the slug, upon contact with the shield, interacts in such a way that the kinetic energy is transformed into work, and then into force, and it is this force that the shields can only withstand so much of. However, for a slug to damage the ship's exterior, some of the slug would have to travel through and impact the hull, since to my understanding KE cannot be transmitted as other forms of energy could. It needs an object to impart that energy to another object, much the same as sound needs a medium in which to oscillate. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 23:07, January 8, 2010 (UTC)

I actually think, rather than force, what you may be looking for here is pressure, or how much force the MAC round exerts over a given area of the shield, and the shield thus may have a limit to how much any small portion can withstand, which would make sense. The APFSDS round fired by the SRS99C sniper rifle has a very small frontal area and very high velocity, thus it is able to punch through several enemies at once. In the same way, in the novels, we see MAC rounds leave holes in the hulls of covenant ships (in TFoR this is prominent) but it doesn't do much to disable the vessel, due to their build quality. Thus, the shields may be unable to withstand such a huge force on a comparatively tiny area, just as the hull is. The force exerted is a matter of how quickly the shield can stop the shell, based impulse-momentum. I can see what you're getting at, but consider pressure. The shields also obviously must protect against force, or rather exert a counter force to stop the projectile. Quakeomaniac 03:24, January 9, 2010 (UTC)

Gotcha. Pressure definitely is involved, but probably should be considered after we settle just how many tons of energy a MAC round has. The pressure talk should go to the shields page when we can explain/speculate how the Covenant shielding is so advanced and all but can't stop a simple metal slug (even though it is traveling at near-rrelativistic speeds). File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 03:29, January 9, 2010 (UTC)

I personally think that the simple explanation is just for storytelling purposes. I doubt the authors of the novels considered logic or consistency too much when the books were written. In fact, from what I can see of Halo Wars Genesis on this site, the lone ship at the second battle of harvest withstood a tremendous battering of nukes and MAC rounds. Now, for a while the supercarrier page possessed this information, as it seems people came to the conclusion that by the size of that vessel and its immense power, it must be that ship. However, it could have been a more typical covenant ship, albeit a rather strong one. So, we can't really say for sure who is right, the novels, or Genesis. If it were my choice, I'd say its more likely that Genesis is right, and that covenant ships are probably tougher than the novels let them be. In the novels, human ships can win with reasonable ease. I mean come on, in TFoR, the puny Pillar of Autumn soloed a covenant cruiser 3 times longer than it, the supercruiser, and I consider that highly improbable and retarded, and I posted that on the talk page. Our long conversation here has come up with more interesting ideas about how shields work than about the original topic, the yield of the MAC. I'm going to say that A) covenant ships are LIKELY more durable than they appear in the novels, and B) the MAC is almost certainly less powerful than the calculations from canon info give. Let me know if you agree with that. We can continue talking about shields on that page haha. Quakeomaniac 04:19, January 9, 2010 (UTC)

I agree with both of your assertions. The List of Inconsitencies in Halo certainly bears testament ot the fact that the novelists and designers did not put a whole lot of thought into synchronization and consitency when they each put together their works. I move that we do some good 'ol physics to calculate the correct energy value. All we need is the mass. We can assume that the velocity is between .4 and .5 c. Using that in the KE equation would give us the kinetic energy, and from their (in the shield page) we could thoerize why it is that one weapon is more effective than another against Covenant shields. (PS I sent you an invite for your consideration) File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 05:18, January 9, 2010 (UTC)

Funny thing is, the 1.17 teraton figure comes from the 600 ton shell stated in the novels and the presumably 40% of C muzzle velocity found in the encyclopedia, which is what started this entire amusing debate... oh what to do now. The velocity is what's likely horribly wrong anyway, because that is what makes the energy so unrealistically high, as velocity is squared in the KE equation, mass isn't. Quakeomaniac 05:38, January 9, 2010 (UTC)

But the tonnage is weight not mass, so it must be converted for it to work in the equation. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 05:41, January 9, 2010 (UTC)

You can trust me on that one, it is, the SI unit of mass is the kilogram, and there is a conversion factor for tons to kilograms i.e 600 tons is about 544,000 kilograms. I can verify the result of 1.17 teratons is (sadly) what the canon information yields when you bring in physics. Quakeomaniac 06:11, January 9, 2010 (UTC)

Ok so I lied, the result I calculate is .94 teratons or 940000 gigatons, but regardless, that's still WAAAAAAYYY too big haha... Quakeomaniac 06:13, January 9, 2010 (UTC)

I confirm the math. I got 1.37 teratons though. I will try again tomorrow, with more precise methods. I don't grasp the immensity of this energy, so I'll also compare it to energy values I am familiar with. File:Gunnery Sergeant.png ΘяɪɸɴF22 Me Talk Contributions CAG 06:30, January 9, 2010 (UTC)

I just want to put up a hilarious result I got doing some calculations. If the super MAC can fire a 9.98 teraton shot every 5 seconds, this requires a power supply capable of outputting over 8 trillion gigawatts of power, not to mention doing that wirelessly. Call me crazy, but I'm going to say this is impossible. Quakeomaniac 21:04, January 20, 2010 (UTC)

A further thing I noticed. The article even states the standard ship based MAC is a 600 ton projectile at 30,000 meters per second, or .0001c. This yields nowhere even CLOSE to 1.17 gigatons of energy, but more like 58.6 kilotons, a FAR more realistic answer. The whole .0001c velocity also implies impossibility for the super MAC velocity of .5c Quakeomaniac 23:28, January 25, 2010 (UTC)

That sounds like it explains it. I have no idea how they came up with the other values then, if the information needed was already in the article. File:Lieutenant Grade One.png ΘяɪɸɴF22 Me Talk Contributions CAG 23:30, January 25, 2010 (UTC)

Ok I just have to throw this out because it's the most hilariously improbable thing I've calculated yet. If you go compute the required acceleration for a projectile to reach .5c within 1336 meters (the length of the ODP), you get but a mere 858 billion G's. I dunno about you, but I feel that would destroy anything ever... haha. Now if you're familiar with mass effect, a game whose warships use a very similar main armament to the MAC, their dreadnoughts (of very similar size to the marathon or halcyon classes) fire projectiles that are a mere 20 kilograms in size at 1.3% of lightspeed, but this not only gives the perfectly reasonable 38 kiloton yield, but the also reasonable 250 G's of acceleration (assuming a 1000 meter ship). Quakeomaniac 23:37, January 25, 2010 (UTC)

Oops I lied make that 825 million G for the mass effect ships... hah my mistake. Quakeomaniac 23:40, January 25, 2010 (UTC)

Yes. We now have conclusive evidence and lasting proof that the original MAC yields were impossibly high. I think the article should be changed to reflect your calculated values, and make sure to include proof (the math) so others don't automatically jump to conclusions and think the value is wrong. On the subject of G's, a regular washer cycle spins at about 79G's of centripetal force. Haha. File:Lieutenant Grade One.png ΘяɪɸɴF22 Me Talk Contributions CAG 23:42, January 25, 2010 (UTC)

Yes indeed I very much agree. It's about time we brought this insanely long topic to a close. However, because I don't want a bunch of insane flamers coming after me for betraying the halo bible (the encyclopedia), I'll leave it up to an administrator (preferably) or another editor to make the changes if it is seen as desirable. I appreciate all your input to the discussion Orion. Quakeomaniac 23:55, January 25, 2010 (UTC)

I can understand that. People these days...it was agreeable talking to you as well. Hopefully this lengthy discussion will end up bettering this community. File:Lieutenant Grade One.png ΘяɪɸɴF22 Me Talk Contributions CAG 00:13, January 26, 2010 (UTC)

“Quakeomaniac does have a point, if not to point out the inconsistencies of Halo. The Covenant shields do seem to possess different outputs and strengths, as many different weapons of different yields can be used to tear through their shields. A teraton range does seem unrealistic if a megaton warhead is enough. I would think that ships armed with MACs would have little trouble against Covenant ships. Aiming would be the hardest part. Can you be more clear on your 1.2 Petaton assertion? That seems like an AWFULLY large yield for a mere nine warheads, even if they are fusion. As for Star Trek, yes the stuff is impossible, but the creators hired scientists, physicists, and other experts in the field to literally invent futuristic devices, sights, concepts, and technology that was not only futuristic and cool, but also scientifically possible, meaning we as the modern human race could produce it or find it given the proper resources. Everything on that show is something that could theoretically exist (can't speak for the new movie).”

1. The 1.2 Petatons is a low using the Inverse Square Law for the shattering of the moon (see the NOVA bomb page). In the end each of those nukes is 1/900th the yield of the NOVA.

2. ALMOST NOTHING IN STAR TREK IS SCIENTIFICALLY POSSIBLE. This is the show that has blacks holes with cracked event horizons, Super Nova that can wipe out a large area of the galaxy, and were half an ounce of Anti-Matter can blow half the atmosphere off an M-class planet. Only a very few things in ST are possible, hell the book “The Physics of Star Trek” evens says most of the stuff is impossible.

“I appreciate you taking the time to consider what I said Orion rather than just call me an idiot with a bunch of nonsense. Regarding the inconsistencies, here's an interesting one. The page for the covenant carrier states it can withstand 3 MAC rounds (not sure where that comes from, I'll just take it for now). Yet, the supercruiser in TFoR also took 3 MACs and a bit more (the archers) to drop its own shields. This implies that the carrier and supercruiser, two drastically different sized ships, have roughly equal shields. Makes little sense. This could perhaps be rectified if we knew the yield of an archer missile relative to a MAC round, but we assume its low based on the book. As for the guy who doesn't bother to sign his comments: Yes, this is sci-fi, thank you captain obvious. This does not prevent a meaningful discussion of it. As far as canon, that's the whole point I'm making, nothing agrees. As for the supercruiser, can you tell me where I mentioned the archer missile part? The GoO assertation doesn't need comment. Also the NOVA bomb is nowhere near a normal nuke, and the technology used in it is NOT used in the reactors on ships, which is what powers the MAC. And I'm not trying to state the SMAC can't fire every five seconds, merely that its energy usasage (if it's a 9+ teraton shot) is unrealistically enormous. Anyway, please consider what I said and try to have a meaningful discussion on it rather than insult me.”

I have. I am sorry if I insulted you, I was just in a hurry to get that posted was all. I meant no offense.

1. It may have been because the Super Cruiser was low on power from firing the Energy Projector at the moment.

2. Not only that Keyes wanted to get the PoA away from the ship because he was afraid that even at a distance I believe in the hundreds to thousands of kms here thought it could damage the ship which gives a very high yield.

3. We must also note that an Archer missile was able to chase after for a few seconds a Covenant ship going 100,000 KPH, so I’m surprise they put a warhead on since the KE would be in the MT range.

4. As I said before sorry. But in Sci-fi things that just shouldn’t be possible happen like with ST. Also. You didn’t mention Archer missiles, I was just pointing out that the 3 MAC rounds and 500 or so Archers downed the shields.

5. The NOVA Bomb is stated to be made up of 9 fusion warheads that have the yield increased a hundred fold, meaning that each nuke making up the NOVA has 1/900th the yield of the NOVA bomb going off.

6. Lets look at high yields and ship ranges and stated speeds from the games and books now, shall we?

A. Halo:CE when the PoA fusion reactors goes off the fireball is over a thousand kilometers across giving it a yield of 100+ Teratons.

B. Halo:CE the Longsword on fusion power is able to cross 20,000 kilometers in 90 seconds.

Both of these examples would be impossible with real-world fusion. Continuing now:

C. Halo 3 the Covenant are able to in a short time with a small fleet uncover the 108 km Ark Portal in hours.

D. Halo 2, once the Covenant fleet has entered the effective range of the SMAC stations even the ships are firing which supports a higher speed for the round then the silly 30/km second round that crossed 3,000 kms in seconds from TFoR.

E. Page 8 of TFoR a Covenant fleet of only 36 ships removed the oceans and atmosphere of a planet in 1 hour which gives us Teraton range yield.

F. We also have the Captain of a UNSC frigate state his ship can do 80 million KPH which also puts it above real-world fusion.

G. FS a the AJ-Gettysburg is able to pull around 6400 Gs when it accelerates across 10,000 kms in 18 seconds or so which gives us just under a Teraton for engine output there.

H. Halo 3 the FuD is able to cross a greater distance in a similar amount of time to the Longword in Halo:CE.

It seems to me even parts of the game agree with low GT to low TT firepower.—This unsigned comment was made by 207.200.116.136 (talk • contribs). Please sign your posts with ~~~~

Mr. Anonymous User 207.200116.136, are you asserting that Star Trek is for the most part impossible? Secondly, I'm unclear what you're getting at with your post. It looks like you're backing us up by bringing more inconsistencies to the table. Is this correct? File:Lieutenant Grade One.png ΘяɪɸɴF22 Me Talk Contributions CAG 03:06, January 26, 2010 (UTC)

To begin with, I always thought of Star Trek as one of the universes that tried to be accurate. Possible today? No. A lot of Star Trek though doesn't really violate the laws of physics, but at the time it was made, these things, like antimatter, were not nearly so well understood as today. Incorrect numbers I will give them a break for. I also don't know what you're trying to say. Please back up what you have said with some sources, as I have no idea where you're getting a lot of this, and I'm familiar with all but the two newer novels. I'm not trying to necessarily say you don't have any argument, but please indicate where you found this. The one part I can safely comment on though is the supercruiser. Why would a ship be designed so that it could not fire its weapons without draining its own shields? Halo Wars Genesis and Legends (I think) depict a battle with a SMALLER covenant ship being tremendously harder. I seriously doubt low on energy is a realistic reason if the ship fired one shot. After all, it fired 5 at once earlier. Quakeomaniac 17:48, January 26, 2010 (UTC)

orionf22@ I can agre that some things in ST are possible, but we have thngs like their ships having 64 MT torps, and yet in DS9 and yet we are told The Die is Cast that in 6 hours they would have stripped a planet down to the core. Voy we have the cracked EH, an FTL super nova etc. We have the new movie with the Black Hole creating Red Matter, the SUPER NOVA OF SUPER DOOM that blew up a large section of teh galaxy...at FTL speeds. Trust me, ST is anything but possible, and less consistent then Halo.

And what I am getting at with my post is that the low MT to KT range makes no sense when you look at a lot of the shown feats, even the games support me in some cases.

Quakomaniac@ Not really, you can see some of what I posted above. Still, the shows are good.

F is just before the Covenant ship jumps off the bow of teh Commonwealth in TFoR. So between Pg. 100 and 110. Also note that Spartans could chase after the Covenant ship that was moving at 100,000 KPH.

G is from FS when they are in the Slipspace bubble fighting the Covenant fleet.

On the Super Cruiser, the AJ-type ship was shown in GoO during the battle above the second ring to lose power to most systems as I recall. The weapon just appears to be a massive power hog. On the 5 shots, are you talking about when it took out the 5 UNSC ships? Because that was just one shot that took out all 5.

The only reason I support the TT yields is because of the Encylopedia and what the Covenant can do with a full scale glassing.

I would be happy with the low GT yields for the Ship MAC since that would also fit with the 50 GT SMAC. Also, sorry for any spelling errors, but my PC is a bit slow right now so I can't really go back and check at this time.
