So you are saying there was no contact or trade across those deserts and mountains? Also, if those same features are so impossible to cross How could Cao Wei prevent the Shu from possible contact.Those mountains and hellish deserts are quite large you know.
Buhahahhaha. a) the Han had almost no influence in india and b) you talk about conquering the Gupta as if they weren't a state with a greater population than rome (and more concentrated to boot), an advance war machine with great seige craft and a steel bow technology that could easily move to counter any reasonable roman 'pila' technology that could be developed in the short timespan by secret researchers. Plus why do the Romans want india - they have quite enough to bring under control already.
India historically has had a prominent reputation for its steel weapons. One of these was the steel bow. Due to its high tensility, the steel bow was capable of long range and penetration of exceptionally thick armor. These were less common weapons than the bamboo design and found in the hands of noblemen rather than in the ranks. Archers were frequently protected by infantry equipped with shields, javelins, and longswords.
This is what NK was talking about with 'double planet' with earth having such a large partner. Do you realise what vast and innumerbable effects this would have on the billion year history of this planet? For starters Earth would most likely be tidally locked to Dagger, and have all the continents clustered at the sub-Dagger point.

Hint: those were fantasy, as is yours - when you went asking for critism we assumed you wanted your one to be more realistic.
The mountain routes to Burma are pretty difficult too, and jungle and disease soaked as well - not suitable for major goods transport until major developments had occured, and not route a state could project power (which is your 'reason' for them wanting to contact the magic Romans). Any southern chinese influence in india is going to be minor, and not in the form of armed interventions, so you can just ignore them altogether if you want...
Trying != Success you know - maybe the reason its not mentioned elsewhere is its abysmal failure?
The best evidence for civilian settlement comes from Waldgrimes. Waldgrimes is located close to the headwaters of the Lahn River, east of the legionary base at Mainz. A forum was discovered during excavations at Waldgrimes. The forum stood at the center of Roman civic life and the presence of a forum shows that some Romanization was occurring. Not only was a forum discovered but other unmistakable sign of civilian settlement was discovered. Lead water pipes and a retail center have been unearthed.[17]
Considering that the Romans came from an urban society it is possible to see that they saw small Romanized towns developing and believed that Germany as a whole was becoming pacified and Romanized. This matches Dios statement that the Romans had control of some parts of the country but not others. Dio continues by writing that some of the German tribes were becoming romanized.
Yes, of course, that almost goes without saying. What seems to be the main complaint here is the disturbingly large number of butterflies involving extremely rapid technological progress in one country, combined with the virtually uncontrolled and unchecked expansion of said country into regions that would be at best difficult to take over. Besides, most of these timelines were developed with the intention to use them as settings for NESes,
but as soon as we hit the era of the Crisis of the Third Century Rome would be forced to relinquish Germania just like Dacia, although it would provide a handy buffer zone and possibly would lessen the impact of the invasions somewhat, giving us an overall richer Roman Empire as we go into the fourth century.
Crisis of the Third Century (also known as the "Military Anarchy" or the "Imperial Crisis") is a commonly applied name for the crumbling and near collapse of the Roman Empire between 235 and 284 caused by three simultaneous crises: external invasion, internal civil war, and economic collapse.
An invasion by a vast host of Goths was beaten back at the Battle of Naissus in 268. This victory was significant as the turning point of the crisis, when a series of tough energetic soldier emperors took power.
Internally the empire faced runaway hyperinflation caused by years of coinage devaluation. This had started earlier under the Severan emperors who enlarged the army by one quarter and doubled the base pay. As each of the short-lived emperors took power they needed ways to raise money quickly to pay the military's "accession bonus" and the easiest way to do so was by simply cutting the silver in coins with less valuable metals. This had the predictable effect of causing runaway inflation and by the time Diocletian came to power the old coinage of the Roman Empire had nearly collapsed.
One of the most profound and lasting effects of the Crisis of the Third Century was the disruption of Rome's extensive internal trade network. Ever since the Pax Romana, Imperial Rome's economy depended in large part on trade between the Mediterranean ports and over Romes extensive road system. With the Crisis of the Third Century, however, this vast trade network broke down. The widespread civil unrest made it no longer safe for merchants to travel as they once had, and the financial crisis that struck made exchange very difficult.
Dozens of formerly thriving cities, especially in the West, had been utterly ruined, their populations dispersed, and with the breakdown of the economic system most could not be rebuilt. Major towns, even Rome itself, now became surrounded by thick walls they had not needed for many centuries.
More rationally, while I agree that growth is key to survival, growth will eventually hit a snag. The Roman Empire already was quite overstretched; conquest of Persia and many other places besides would stretch further. You see, although growth is necessary, an empire set wholly around the Mediterranean was optimal, and even that had many problems. If you also try to control Persia and Arabia, and expand in many other regions, there would be a basic problem of communication, not to mention overstretchment of Roman resources, which were not infinite and were severely hurt by assorted social difficulties that had quite little to do with lack or existence of expansion (admittedly, if you have enough sufficiently dedicated emperors fortuitously placed along the timeline they should keep things running with occasional social reforms). But really, the problem of communication is much more severe.
Nope, never claimed it at all. please read the relevant post.
You're making alot of friends, you know? And I did read the post- you're attempting to correct alex, the most annoying sinophile anyone will ever find.
No one has answered my question yet.
It dosen't seem to be that much different than a non-earth pod to be honest.Maybe no one has answered your question because to do so would require knowledge of climate, tides, terrain, etc., and even if one had that data, would require us to recreate history from the foundation of civilization until whenever you wanted us to stop, which is too much work for us to do for a project none of the people you are asking seem particularly interested in.
How in the heck did I turn earth into a double planet? Are you even reading the same timeline?
CONSTRUCTIVE criticism is something completely different from what you have posted. From the beginning you, my friend, have done nothing but non-constructive criticism. I have said before if you have criticisms present them with helpful suggestions.
What it seems to me you dislike is the fact it diverges too much from your perception on how history should go. Well, I hate to tell you, but you cannot know all possible divergences in history that the Many Worlds Theory of Quantum Mechanics supposes. Read up on it sometime.![]()
What you seem to forget is ALL AltHist is fantasy.
As for posting here, who died and made you god?
See another person's post. Apparently you need to look up the definition of a double planet.
You are correct. I was incorrect in my estimations of size. The Terra - Pugio Caelum system has been rearranged to these figures:
Code:Earth Moon Mean diameter 12,742 km 3,476 km Volume 1.08321 x 1012 km3 2.199 x 1010 km3 Mass 5.9736 x 1024 kg 7.349 x 1022 kg Mean density 5.515 3.342 Surface gravity 9.78 m/s2 1.62 m/s2 Escape velocity 11.2 km/s 2.38 km/s Visual albedo 0.367 0.12 Visual magnitude -3.86 +0.21
The Earth-Moon System
The moon is the earth's nearest neighbor in space. In addition to its proximity, the moon is also exceptional in that it is quite massive compared to the earth itself, the ratio of their masses being far larger than the similar ratios of other natural satellites to the planets they orbit (though that of Charon and the dwarf planet Pluto exceeds that of the moon and earth). For this reason, the earth-moon system is considered a double planet. It is the center of the earth-moon system, rather than the center of the earth itself, that describes an elliptical orbit around the sun in accordance with Kepler's laws. It is also more accurate to say that the earth and moon together revolve about their common center of mass, rather than saying that the moon revolves about the earth. This common center of mass lies beneath the earth's surface, about 3,000 mi (4800 km) from the earth's center.
This is called lecturing, and it's rather arrogant of you to assume I've not heard about that "theory".
I'm perfectly willing to discuss anything constructively, but apparently you can't take criticism and must hide behind your shield of newness. So be it.

No one. I have never claimed lordship over this forum; nor will I ever. Nor have I declared jurisdiction over who may and may not post. That is simply not something I do. The most I have done is simply pointing out the absurdity of Rome discovering gunpowder, and explained why in later posts. After a while of you claiming to know every motivation I have, I snapped. Regardless of why you're on here, I'm not on an internet forum to exercise "power", so stop your projecting, and stop claiming to know what motivates everyone else.
Now, it's all well and good that you post fantasy -- I frankly don't care, though I'd rather you didn't post it in the alternate history thread
Dude you have some serious ego issues.
Did you miss this part of my previous post?
And i think you need to refine your definition since the Earth - Moon system is considered a double planet to. My error was in my estimation of Luna's size, yours is of arrogance:
Your continued actions deny that statement. I held out the gauntlet of peace you threw it back, well no one can say I did not try.
I have five, thanks anyway. But it seems you need one bud. I highlighted the relevant parts just in case you missed this like you did my correction of my Lunar sizing:
Once again, ALL AltHists are a form of fantasy.
Then you telling me to not post here was my imagination?
Man I have one heck of a imagination if I can conjure that in reality. I never claimed to know what everybody's motivation was. Only you.
Yes, I am aware of that (nice quote from the Wiki article). Apparently you didn't get the point -- changing the gravity of the Moon massively changes Earth along with it. And you still assume humans evolve on it. There is a problem here.
Apparently you're not getting this. There's more than one definition of fantasy, as you evidently know, since you posted them. Now, one type of fantasy is imagination. Applying this to alternate history works. Then there's another way of taking it: a world where physical laws aren't taken into account. To do what you've done in this timeline is taking the latter approach, which is not alternate history. Thank you.
By 1928, Fleming was investigating the properties of staphylococci. He was already well-known from his earlier work, and had developed a reputation as a brilliant researcher, but quite careless lab technician; he often forgot cultures that he worked on, and his lab in general was usually in chaos. After returning from a long holiday, Fleming noticed that many of his culture dishes were contaminated with a fungus and he threw the dishes in disinfectant. But on one occasion, he had to show a visitor what he had been researching, and so he retrieved some of the unsubmerged dishes that he would have otherwise discarded, when he then noticed a zone around an invading fungus where the bacteria could not seem to grow. Fleming proceeded to isolate an extract from the mould, correctly identified it as being from the Penicillium genus, and therefore named the agent penicillin.
I said I'd rather not see fantasy in the alternate history thread.
Now, it's all well and good that you post fantasy -- I frankly don't care, though I'd rather you didn't post it in the alternate history thread
Yet above in this same post, and in multiple other posts, you have expressed the belief that you know what motivates me. You claimed I was elitist, had a class thing, and didn't like newbs posting in this forum. None of these claims are true. Any kind of problems I have with you stem not from your newness, but your words.
Now, I'm going to make my position on this quite clear. It's well and good that you disagree with me on historical matters. I'd have let go the gunpowder thing, and while I freely admit I'd have stopped reading your timeline after the thing with space aliens, I certainly would not be in the rather hostile mood I am now. I would let you keep your opinion, no matter how wrong I thought it to be, and keep it in peace.
However, you crossed a line. You made accusations at me, you launched ad hominem attacks, and generally tried to paint me as a newbie-hater. When you do this, you are not being a good debater, and you are certainly not offering any hand of friendship (except, perhaps, in sarcasm). You are merely being rude.
Feel free to call me sarcastic, rude, or, if it please you, an utter jerk. I'll live. But do not presume that you know the motivations, feelings, or prejudices of myself or anyone on the internet.
And you are apparently not getting the point, posted twice now, that I have changed that. So want to elaborate on how you keep missing that salient point?
I am still waiting to see how you justify calling Roman invention of gunpowder a violation of any laws of physics that I am aware of. They had access to saltpeter, Sulfur, and charcoal and these substances were used everyday. So how is their combining three well known and available elements a violation of physical laws? Please by all means present your evidence as to how this is a violation of said laws.
And from what I get from you, it takes decades or centuries to develop technology. No possibility for random chance to affect any outcome.
So how does your hypothesis support well known inventions that were accidental? Such as Fleming's 'discovery' of the Penicillin bacilli.
Thgis by itself invalidates your claims it takes centuries or dedicated teams of researchers decades to develop technology.
What you actually posted was the following, the relevant point is highlighted:
Now the word "you" indicates you pointed that sentence directly at me. If you had not included the word you, then you could squirm out with the explaination it was a generic statement. But it was nothing of the sort.
There's that arrogance again, how do you presume to take my opinion or my expressing of it away?
I let it go a few posts back, but you drug it back up. I am a counterpuncher. I only throw back what comes at me.
So you are saying there was no contact or trade across those deserts and mountains? Also, if those same features are so impossible to cross How could Cao Wei prevent the Shu from possible contact.
B,. So you are saying the Guptas could not be overcome? Hmm, according to the history I have read In the 480's the Hephthalite king Toramana broke through the Gupta defenses in the northwest, and much of the empire was overrun by the Huna by 500. The empire disintegrated under the attacks of Toramana and his successor, Mihirakula; the Huna conquered several provinces of the empire, including Malwa, Gujarat, and Thanesar, broke away under the rule of local dynasties. It appears from inscriptions that the Guptas, although their power was much diminished, continued to resist the Huna, and allied with the independent kingdoms to drive the Huna from most of northern India by the 530's. The succession of the sixth-century Guptas is not entirely clear, but the last recognized ruler of the dynasty's main line was Vishnugupta, reigning from 540 to 550.
As for those steel bows lets see what history has to say about them.
So it seems they were found only with the noblemen, making the majority of the ranks using the fine bamboo long bow using bamboo cane arrows with metal heads. So it seems another obstacle is overcome.
I was asking for constructive criticism along with suggestions for change. But right from the beginning there was only hostility, derision and scorn. Nothing constructive about that. So once, again, if you have some suggestions for change, by all means, suggest away.
Yes they are, but difficulty has never stopped diplomacy before.
There was no major goods traffic as you say. I stated merely a diplomatic mission to obtain the secret of fulminata. Nothing more. If I have done so please point it out.
Please read the article. It stated it had been there for at least a decade before abandonment in 9 AD due to being burnt down after the Varus disaster. That is not indicitive of 'abysmal failure' as you put it, but a act of war.
The only real technology introduced is Gunpowder. Everything else is an extrapolation of what that one change would lead to. Heck, gunpowder is an extremely simple substance. It is not even a compound, being merely a mixture of potassium nitrate, common charcoal, and sulphur. Any blend of roughly equal proportions of sulphur and charcoal with from 40% to 75% of potassium nitrate --saltpeter-- will flash with considerable noise and may thus qualify to be called "gunpowder".
The Romans knew of saltpeter, had large deposits of sulfur in Scicily and used charcoal all the time. So it is quite possible for someone to stumble onto its discovery, as long as the required ingredients are available society. You all have shown the way I have described it is fanciful, but at the same time you refuse to admit it can even enter the realm of possibility. So by all means, suggest a new approach to the problem. After all, that is why I originally posted it here.
1. External Invasion. With the inclusion of the new provinces the invasions are lessened and their impact is much reduced. I have addressed that with the Gothic attacks. And I had them break through the frontier ravaging the new provinces but leaving the core provinces untouched. So you do not have the Goths running amok in Moesia, pannonia, Dalmatia, Thracia or Greece like in OTL.
3. Without the short-lived emperors there is no need to debase the coinage to keep raising the pay to keep the legions loyal since a stable system of succession had been adopted.
Yes communications are the major snag in any nations expansion problems. As for Arabia, the Romans were already present in OTL up to the first cataract, so it is not much of a leap over into Arabia along the coasts. I would also expect the Romans to use water travel, river and ocean to keep in contact with their far flung territories.
1545 793 For the first time in centuries an outside force began to raid Roman territory. A Norse raiding party landed on the east coast of Caledonia and sacked the Roman town of Devana (Aberdeen). The commander of the Classis Britannia dispatched a squadron of 6 sail equipped triremes to catch the raiders. The entire squadron was destroyed by the superior ships of the Norse squadron. The Roman Governor of Britannia shrugged it off as just another pirate raid.
...silly - the romans don't have the seamanship or skills to crew a long boat, and since the romans have no intention of going raiding what would be the point of them? They would simply outrun the rest of the fleet and be crushed by the experienced Norse. Th romans need big sail ships like caravels to catch and pound the longboats.so Arrius decided to build a fleet based on the captured Longship

Thanks. I guess Pompey is all too accurate, especially given the next installment of the Eastern Roman TL.As the only member of the Alt-historian Triumvirate (a position I just now made up to describe those who have posted multiple alternate histories in recent memory and includes das as Julius Caesar, dachspmg reprising Pompey Magnus, and myself holding down the lovable spot of dear Crassus) not to have commented on the timeline, I feel it is my duty to strike once more at the dead horse.
So long as we're not straying into the realm of probability here, just possibility, then I'll generally be fine with this as well.@ Strategos, thats all I was trying to imply is that it is possible. And I had begun to think that the crux may have been the definitions you described. I am content to say it is possible, and not very probable.![]()
While not outside the realm of possibility, a unified Norseland this early is highly unlikely. The geographical isolation that the fjords are in militate against much of a central authority, though a Celtic-type "High Kingship" is somewhat in order beforehand I guess. That "High King" would be unable to coordinate raids or invasions effectively though.Thorgrimm said:1587 833 For the last 40 years there had been peace. The Norse had been preparing for a full-scale invasion and from 833 onwards, hardly a year went by without a raid being reported to the Governor in Londinium. The Romans still believed that the raids were random acts of piracy and therefore relegated the threat to minimal.
This is probably just nitpicking, but it's actually the other way round: Norse longships are designed for shallower waters (their draft isn't very much), while Norse seamanship gets them across the oceans, or in this case the North and Norwegian Seas.Thorgrimm said:The Norse on the other hand had their longships. Ships that were designed with the oceans in mind. That and the Norse were natural sailors since it was far easier to travel in their lands by sea.
The original reason for the creation of the NES subforum's alternate history thread series (the first one was, gasp, a poll done by Amenhotep7) was to come up with settings for NESes, so naturally we're sort of biased that way, towards a scenario that retains some historicity and provides a good setting for a NES. So long as there aren't any pretensions towards remaining in the probable as opposed to the merely possible, then I can't honestly say that you ought be met with any sort of hostility.Hmm, thats probably why all the hostility. I thought this was a thread to discuss althists, but if it is for coming up with backgrounds for NES's, that would explain it. My bad.
My argument was aimed primarily at destroying the likelihood that these new provinces would even be seized in the first place, especially in the volume they were (having admittedly only skimmed the TL at first glance). There simply is no reason for the Romans to take over Germania and Scythia other than to safeguard against a possible barbarian attack (assuming massive preplanning by the Romans and a collective strategy over the course of multiple emperors), in which case the only Romans in the new provinces would be military (for there is basically no reason for civilians to settle in the impassable German forest or the open plains of Scythia, until they become somewhat profitable by diffusion, and besides, as I believe Dis has previously pointed out, Scythia can't become anything but pastoral for a few centuries at the least and a millennium at most). If the only Romans in the provinces are military, then they will be sparsely populated, because Rome hasn't got the cash to pay a military large enough to cover Scythia and Germania without a civilian infrastructure and cover the already existing provinces as well. Sparsely populated military indicates that the Goths and their ilk would have a relatively easy time of smashing through the frontier and getting to the Danuvius, Rhodanus, and through the Caucasus, thus leaving us at square one again. Besides, the Roman infantry-based system of warfare just doesn't really work on the steppes all that well, even with guns.Thorgrimm said:1. External Invasion. With the inclusion of the new provinces the invasions are lessened and their impact is much reduced. I have addressed that with the Gothic attacks. And I had them break through the frontier ravaging the new provinces but leaving the core provinces untouched. So you do not have the Goths running amok in Moesia, pannonia, Dalmatia, Thracia or Greece like in OTL.
Because every emperor will use the adoption system.Thorgrimm said:2. With the Romans still focused outward instead of inward there would be avenues for the glory and power seekers routes to power besides internal strife, especially with the adoption system I used. Then add there is no Sassinid support for Zenobia there would be even less desire to break off from the empire.
I'm pretty sure Octavian didn't have clairvoyance or influence over the Goths' actions centuries into the future; otherwise, how would he have screwed up so badly?Thorgrimm said:I just introduced it a bit earlier, which is not beyond the scope of Octavian's capability of implementing.
And, as before, I disagree that this system of succession is inherently stable, because none is, due to that lovely thing called human agency. I suppose you could theoretically have no Emperors with children, and all of them are competent or better because they choose successors who always are, and who never descend into madness or megalomania or anything like that, and who are in fact the superhuman and divine beings that they proclaim in their titles. This, however, lies in the area of possibility, not probability, which is a more fundamental dispute as previously enumerated.Thorgrimm said:Without the short-lived emperors there is no need to debase the coinage to keep raising the pay to keep the legions loyal since a stable system of succession had been adopted.
Yes, and as I have previously noted I believe the argument that Gaul and the Balkan provinces would not be raided to be inherently flawed and thus inadmissible. However, since we aren't dealing with what's probable, merely with what's possible, then we can completely ignore problems like that. Nice how that works as a catch-all to eliminate little things like logic or reason from the enterprise.Thorgrimm said:Without the ravaging of Gaul and the balkan provinces, the rise of Zenobia or the Gallic Empire to disrupt the internal Roman economy I believe there would be no such economic collapse.
Already pointed out that changing the nature of the system has effects on evolution -- even if the change is lessened. Really, I grasped your point quite a while ago.
Forgive me for being a bit nonspecific. Changing the Earth - Moon system without changing anything else is a bit of a violation of physics (yes, I realize you changed it), whereas I suppose inventing gunpowder in the first few centuries AD more falls under the rules of common sense.
Depends on the technology. Some do take centuries to develop, yes. The invention of gunpowder may have been somewhat random, but it definitely had many years knowledge behind it.
I challenge you to support the assumption that Fleming's discovery could have been achieved without several centuries of biological development behind it. I also challenge you to support that it could have been utilized without that biological knowledge. Killing bacteria doesn't mean much if you don't know what a bacterium is.
It would have been a magnificent refutation, if I actually claimed that. I'm a believer in random chance. I certainly don't think you require a dedicated team of researchers, otherwise we'd have been in trouble as a species, the Scientific Method being a rather late concept.
You're putting the emphasis on the wrong word.
"Now, it's all well and good that you post fantasy -- I frankly don't care, though I'd rather you didn't post it in the alternate history thread"
It was hardly a prohibition on posting, it was a preference for taking off-topic material into other threads.
Nice try. Let you keep it merely meant I wouldn't have been actively attacking it. Funny that you try to claim I wanted to restrict your right to post when the quote was taken out of a paragraph saying I didn't want to do just that. Please take it in context, or don't quote it at all.
Hey, I'm just explaining my apparent "ego problem" and "arrogance".![]()
Your reason for the romans giving up their secret to to remove interference by the Han, which is silly as the Han states can't interfere and both of them should know that
So? Steppe tribes like the Huns pwned the Romans too. The Gupta inability to deal with a very mobile force of steppe cavalry will have little comparison with their ability to deal with massed infantry like what the romans will be presenting (as it appears the Guptas were quite good at dealling with their neighbours infantry armies), especially as the romans will be much less able to live off the land and will be at the end of insane supply chain unlike the Huna.
I never said they couldn't be overcome, just that you were massively underestimating them.
So every roman soldier has Cheiroballista and hand cannons? Thus now raises the question of where the romans are getting the money and manufacturies to build these weapons - gunmetal is very specialised.
1. The culture on this subforum is rather informal - mocking commentary is par for the course and you may be using out of place sensitivities.
2. As Stat said, maybe we are talking at cross purposes, but I hardly see how constructive critisism, a idea based on probablity evaluation and fact checking, can be offered on a 'timeline of possibilities'. "Yeah, here you said they invented gunpowder and then went on to guns, but I think it would be cooler if they invented jet packs instead!!!"
The earliest formula clearly identifiable as gunpowder in Europe is one produced by the English alchemist and monk Roger Bacon (1214?-1292?). Bacon appears to have had some knowledge of the potential of saltpeter, sulphur, and charcoal as early as 1247, when he makes passing mention of it in an essay on the wonders of science. But it was not until 1267 that he specified a formula, in a letter to Pope Clement IV (reigned 1265-1268). This formula called for 41.2% saltpeter, 29.4% charcoal, and 29.4% sulphur, a mixture which will flash fairly convincingly and produce a loud noise, though it would have been a little weak as a propellant, due to its low saltpeter content, thus making it short on oxidizer. This did not, however, detract from the impressive pyrotechnical display. Over the next few decades experiments with the new substance appear to have been conducted with some frequency and several formulae exist, all of which are considerable improvements on Bacon's. By 1275 St. Albertus Magnus (1206?-1280), a German scholastic philosopher and theologian who dabbled in alchemy produced a formula which called for 66.6% potassium nitrate, plus 16.7% each of sulphur and charcoal. This is unquestionably gunpowder, for it will go off with a "bang", though not quite the "bang" one would get from the optimal formula, which is 74.64% pure saltpeter, 11.85% pure sulphur, and 13.51% charcoal.
But experimenting to find the right mix, whilst staying alive takes time. Something you have not accounted for. Also you have not extrapolated (an extrapolation would be taking the development time by Ren Europe, correcting it by the different population and economy size, then +20% for fun) you have given a technological development path so fast (compared to the other developments of gunpowder in europe, the islamic world and china) that it requires additional points of difference.
Your way is more plausible if you have them take a hundred years instead of 20 to stumble upon gunpowder, and then another four hundred to produce basic msukets - which still gives them guns 600 years earlier than the OTL
