@Kevin Just basic insecurity. I doubt it's much more complex than that. Religious beliefs are presented as known facts about the world, but are clearly not believed to the same degree as other facts. If I tell you gravity is an illusion you laugh it off because that's just silly. But, if I tell you god isn't real, it's upsetting. Shouldn't both challenges be seen as equally inconsequential if you're equally secure in the truth of each? Clearly one of these facts is not like the other.

@AbhinavDiddee In the end the real answer is: you don't need to correct her. If it's for a grade, then fight it, but if it's a lecture mistake, just move on. If it's just for the sake of being right, you're not going to gain anything by proving it.

Can you have people worshiping a god that hasn't been born yet? Perhaps people will one day believe that we will create a new god in the form of an artificial super intelligence.

@JBH The easiest stepping stone would be to use a smooth Earth and diverge from there. Stopping the rotation, something that exists on all planets we can observe climate on, complicates the issue rather than simplifies it.
Feb 2, 2018 12:26
@JBH If you think the answer for a perfectly circular orbit and a orbit with an eccentricity of ~0.0167, then you better fix the Sun's output too, it's not perfectly constant after all.
Feb 2, 2018 12:26
"DOES NOT rotate, DOES NOT orbit" - That's effectively the same thing as rotating once per orbit. That is, your situation is the same for a tidally locked Earth-turned-billiard-ball.

@GrimmTheOpiner The sidereal day is longer, not the solar day, which was Michael's question/comment. This question is about solar days, is it not?
Mar 3, 2017 02:44
@GrimmTheOpiner While correct in one interpretation of "day" it's incorrect in the context of this question. A point on the Venusian surface sees about half of a Venusian year of daylight. Not more than a year.

These people wouldn't even have language. What's the use in talking about things everyone can see immediately in front of themselves? The problem with this concept is you've started with a fully formed society, then removed a characteristic required to form a society. You may as well ask what gloves for worms would look like.

@Durakken I am specifically looking for an analysis of the material. To quote from my question "An answer of "the material needs to be, like, wicked strong and lightweight, dude" is not satisfactory. I want to know what materials will work (and calculations showing why), or if none exist, what materials would be required (and calculations showing why)." Similarly and answer of "I just picked the lightest and strongest said to exist." is no good without some numbers to back it up.
Jan 5, 2017 19:45
This is significantly improved from the initial answer. Nice work! The initial question goes unanswered though, you do mention a structural material, but it appears that it's quite squishy thus not suitable for ~150m rigid structural members. Can you expand on what materials would be used for structure and why solar radiation/greenhouse effect won't be enough for proper heating?
Jan 5, 2017 19:45
You're getting ahead of yourself. This question is asking what materials and then what's the carrying capacity. There is no city. We can't add a city and/or people until we know what the carrying capacity of the sphere is. Nowhere in the question does it say there is also a city of unspecified size and mass. It says Fuller wanted to use them for habitats. How many people is that? It could be 1 person in a tent. But I'm not even asking for that, I'm only asking for carrying capacity. Discard your assumptions, read the question, then edit or delete your answer.
Jan 5, 2017 19:45
No other answers actually answer what I'm asking, which is what materials and from that, how much carrying capacity. If I could provide those, my question wouldn't be a question. Residency will be based on the answer to the latter question. Read the question again, those parts have been in bold the entire time. How does a 20% increase in volume increase the mass by more than 100%? Are you changing the density of something? I'm starting to think you either misunderstand the question or lack the education to consider it properly.

@kingledion Well the church always counts dates weirdly. For example if you got stuck in an elevator on Friday afternoon and got out on Sunday morning I'd say you were in there for maybe two days, but the church would say that was three days. Plus, they never have a zero index. That's my three points anyway.
Dec 22, 2016 15:54
@kingledion That source is claiming there is no intentional link to pagan celebrations because "early Christian writers never hint at any recent calendrical engineering". Of course, they wouldn't write about such motivations, would they? As you mention, it goes on to say "From the mid-fourth century on, we do find Christians deliberately adapting and Christianizing pagan festivals." while admitting that as late as the mid 3rd century there was no record of Christmas being celebrated. Given the sparse information, it's conceivable that the date was an early example of pagan festival adoption.
Dec 22, 2016 15:54
@kingledion Bellerophon is correct. The Greeks' celebration emphasized the baptism of Jesus hence the Jan. 6th date. Further: " Various factors contributed to the selection of December 25 as a date of celebration: it was the date of the winter solstice on the Roman calendar; it was about nine months after March 25, the date of the vernal equinox and a date linked to the conception of Jesus; and it was the date of a Roman pagan festival in honor of the Sun god Sol Invictus."

I don't think it's going to be a thing people do in zero-g. Both because of the lack of gravity causing more persistent clouds and the fact that to be in zero-g means your environment is highly regulated and most likely fragile.

@Zxyrra I was alluding that since green isn't included in the Planckian locus, you're going to have a lot of trouble finding something that radiates green.

Find a metal that glows green in some stage when it's heated and you'll have found something to make a star glow green as well.

@hobbs You must interpret the sentence "Their compression and encoding has progressed past the point where we can identify it as a coherent signal." differently than I do. Because it seems to indicate we get the signal but don't have the technology to comprehend it.
Dec 6, 2016 01:36
@JohnColanduoni My point remains. Whether it's a purely binary environment or spherical cows, the real world situation isn't being described accurately.
Dec 6, 2016 01:36
@Shalvenay It really doesn't matter. Even DSSS is sent out at a power significantly higher than ambient noise. It's clearly distinguishable as a signal from the noise. With multiple, non-periodic, signals coming from a star, no matter how noisy would not appear to be a natural occurrence and we would infer a sender. Of course, the obvious answer is we never receive the signals at a sufficient power, but that's not in this answer. This answer assumes the signals arrive, but we don't have the technology to detect them, which is implausible at best.
Dec 6, 2016 01:36
@hobbs Precisely. A signal as I just described would infer a civilization, because natural radio emitter doesn't look anything like a signal suitable for radio communications/broadcasts. If the situation you described arises, that is "okay, I see there's an emitter" then it's not an acceptable solution.
Dec 6, 2016 01:36
@hobbs I think you understand the question differently. Mistakenly, I believe. The question is not about interpretation of the signal, but reception. The OP is asking how to avoid detection, not how to avoid successful interpretation. Any signal suitable for transmission and reception will look significantly different than hydrogen clouds. That is, if we detected it we'd know it was not a natural emission, regardless of knowing the content. The OP is asking how to avoid that detection all together.
Dec 6, 2016 01:36
@hobbs Your interpretation of my tone is incorrect. I know of no way to convince you of that as long as you have that bias. So please discard it and re-evaluate.
Dec 6, 2016 01:36
@Delioth Do note that you are able to apply your "decompression algorithm" to CodeGolf data because it's being delivered to you via the low entropy communication system known as the Internet. Transmitting high entropy data at the same amplitude as noise can not be expected to be received reliably by anyone. Remember that the receiver gets both the noise and the signal, so obviously, being indistinguishable means they won't be able to tell the difference.
Dec 6, 2016 01:36
Or think of it this way if you want a computer science version. Compress your data to the point that you have maximized entropy and it appears random. Now, to simulate a real world effect of radio broadcast, randomly flip a small percentage of your bits. Did that level of compression help you or hurt you? It seems to me that you sacrificed all error detection/correction for the sake of compression. Of course, if the analogy followed the proposed system of being indistinguishable from noise (SNR = 0) you would randomly flip all your bits.
Dec 6, 2016 01:36
@CemKalyoncu, JohnColanduoni, and Delioth Compression induced entropy is not the same thing as noise in this case. You're all coming at this from a computer science perspective of binary values, if only two values are possible, I don't disagree with your assertions. However, for the real world and for a radio broadcast, a signal and noise are very different things. A radio signal which is indistinguishable from noise is not a signal, it's noise. Read up on something you don't have in your purley binary environments called "signal to noise ratio" or SNR.
Dec 6, 2016 01:36
@CemKalyoncu No, it's not going to look like noise at all. If your signal is indistinguishable from noise, you won't be able to distinguish it from the noise. Which is exactly not the point when sending a signal. It will look highly ordered.

@Zxyrra For clarity, the concept doesn't require that the substance is a polymorph of water. Cool breezes can be generated in a plethora of ways that begin with a "detonation".
Dec 1, 2016 16:06
@Zxyrra Well, this particular polymorph for water isn't known to exist (and likely can't). But the concept is not "handwavium". Of course, the way your question is worded, a cool breeze would qualify.
Dec 1, 2016 16:06
I'm surprised nobody mentioned Ice-Nine, the substance in Kurt Vonnegut's novel Cat's Cradle, which causes people and water to freeze by raising the freezing temperature significantly.
 
Dec 1, 2016 16:06
@RogerWillcocks No, it's not. I can't tell if you're asking a question. It's certainly not obvious enough to be rhetorical. We currently use drones in combat, how many have turned against us by our enemies?
Dec 1, 2016 16:06
A manned tank is significantly easier to be pressed into service by an enemy if captured. A whole lot of reverse engineering would be required before an enemy could control a drone tank, assuming it doesn't brick itself after a lost connection timeout.
