Congrats, you have answered literally everything else I was going to ask except my original question.

On what day of the year (on average) would the Northern Hemisphere's food stockpiles be at their lowest amount? How much would this change during a nuclear winter?

Well, I just got my calculations from http://www.stardestroyer.net/Empire/Tech/Beam/Calculator.html Also, I did some calculations on what the maximum population of a miniplanet could be, since the previously mentioned Macau isn't completely self-sustaining as a miniplanet would have to be. So if we use the numbers provided by http://worldbuilding.stackexchange.com/questions/9582/how-many-people-can-you-feed-per-square-kilometer-of-farmland and assume 90% of the planet's land (0.5688km^2) can be used for agriculture that gives us a maximum population of: 1336 people if we use conventional farming 7565 people if we use hydroponics 27990 people if we use aeroponics That's actually more than I expected.

So for an 830m planet with 1g of surface gravity, that's a gravitational binding energy of 6.180E+19 Joules, or 1.477×10^10 tons of TNT, or about 295.4 times the explosive energy of the Tsar Bomba, or equivalent to 688 kilograms of matter turned into energy. That's more than I expected.

I'm guessing the "planet buster" or whatever it's called is just a really big nuke. Would that be possible? Can someone calculate the gravitational binding energy of a mini-planet?

I have a feeling this entire Mars plan is beginning to collapse. If something sounds too good to be true, it usually is.

Huh. I wonder if model rockets (the child-friendly kind) would be able to reach orbit/escape velocity? And how far exactly are the "moons" from their planets? Also, I did some calculations and on the scaled-down scale of the orbits (1AU = 6km), one light year equals 379,446 kilometers, or about the distance from Earth to the moon IRL. This means the entire Spore galaxy is likely less than 38 billion kilometers wide. Actually, since the galaxy only contains about 100,000 stars (and I'll assume the star density is the same as the Milky Way IRL), that means the Spore galaxy likely has one four millionth to one two millionth of the volume, or a width of only 630 to 794 Spore light years, or 239.1 to 301.3 million kilometers. Well, at least that provides a solid explanation to the game's "FTL" travel.

I figured it wouldn't be possible on this scale, since KSP is more focused around almost-planet-sized things. Also in case anyone was wondering, I did some calculations and it turns out a planet with a 830m diameter/415m radius and earthlike (9.81m/s^2) gravity would have a mass of 2.532E+16 kilograms, and an escape velocity of 90.25m/s. If we assume that each planet has the same land coverage as Earth (29.2%), that would give each planet 0.632km^2 of solid land. For comparison, the Vatican has an area of 0.44km^2, and if we use the average population density of the US we'd be able to fit nearly 21 people on said landmass. If we use Macau's population density we can bring that up to 13,414 people. But with the planet's insanely low escape velocity, perhaps that may be enough people to begin a space program?

Someone needs to make a rescale mod for KSP using these measurements. Also someone needs to calculate the Dv the orbit or escape one of Spore's homeworld planets.

This sounds like the most expensive yet most awesome asthetic decoration ever.

Whether its 14 years or 26 years, realistically spending that much time in 0g would make returning to Earth extremely difficult.

Find out what it tastes like.

Well, this bit might happen.

At first I thought structuring your sentence yoda-style you were.

Once the SpaceEngine thing is all finished, we might start on Kopernicus.

It's binary, but a really long distance away from Sol so its hard to tell.

Okay, is suppose it could work that way, just barely.

From that information, I say we could have our first plane in the late 1880s if the calculations were made sooner. To some extent, but only when the change is plausible (eg the USSR was thinking about joining the axis before 1941). No.

Then how could such knowledge be acquired earlier?

I don't have time right now, but i'll do it "soon-ish". I like the idea, so long as Mars is habitable in the 20th century. How would they get there? In OTL we haven't even gotten past the Bedrock Mantle yet!

So it would have a solid surface?

How the wars are fought may change, but the reasoning behind the wars, and to some extent the duration of the wars, would stay the same. I never said it wouldn't. I'll take not of that. Also, interesting discussion about missile accuracies, but how is that relevant?

First, thanks for making a thread for this. As for who would be involved in the Space Race, here is some info I found: https://au.answers.yahoo.com/question/index?qid=20090826132944AArMEBc https://www.makewav.es/story/374214/title/thegreatpowersineurope1900 https://www.quora.com/Who-were-the-most-powerful-countries-in-the-world-at-different-points-in-history So overall we have a few other countries who could compete with the British, creating a space race consisting of multiple players. Wasn't radio already being used? Also, this timeline you've come up with is a bit late. So the motives here would be similar to that of the Space Race I suppose. Good, it sounds a bit like this: http://althistory.wikia.com/wiki/Space_Race_Didn't_End No, probably no and NO. Do you have any idea how big the interplanetary to interstellar jump is? It's about as big as the jump from intercontinental to interplanetary. And why shorten the wars? WW 1 and 2 were both inevitable as direct conflicts. You'd be surprised how capable 1900s tech is with this sort of thing. The US had already surpassed Britain in population, and was rapidly growing. Agreed. Well, not necessarily. There are many other types of ICBMs that could have seen development. Okay, how about I set some actual rules: No technologies that require a POD before 1700. No nukes. No advanced computers. Nothing developed after 1950 in OTL. Something in space before 1895. Some kind of manned orbital spaceflight before 1905. Manned Luna and Aurora landings before 1935. No cancelling any major wars. At least 2 major spacefaring nations outside Europe (probably America and Japan or something).

Probably won't happen.

Great job so far! And here's your update-ly errors list: Venus is still to hot and still has way too much atmosphere Luna still hasn't been large-ified yet, and is it just me or is it stuck in a solar eclipse? Mars is still way too cold Minerva is also way too cold Laythe is also way too cold Everything else is great though!
