Loss of gut bacteria diversity. Same as vegetarians loose the ability to digest meat after not eating meat for years. If their diet were to change, they would be ill prepared to process it after a lifetime of having always the same food.

There are a variety of possibilities, from gut poisoning to completely nothing. It all depends on the amount grown, and in what locality to one another. If they are all grown in, lets say, one building, with thousands of cultures being grown at once, then you could be screwed in a variety of ways. If there is an outbreak of any infections in the food, than ...

No difference. Evolution does notwork on such short timescales. Jews have been cutting off their foreskins for thousands of years yet each new generation gets born with them again. Unless an extremely specific mutation randomly appears in the population, AND that mutation conveys a large benefit to the chances of breeding, AND the breeding successfully ...

The concept of "visible light" is actually way broader than the human vision. It relates also to the photosyntesis, to the transparency of the atmosphere and to chemistry in general. The lower-energy (red) limit is the ability to invoke a chemical reaction in a substance that is generally stable at the temperatures of liquid water. A substance that is less ...

"The main reason behind this question is because I think it would be interesting if there was a situation in which an individual from Alpha Centauri could literally not read a display because of the color scheme, or if conversely they could see something that someone from Sol could not." This is very very obviously possible. Here on Earth, illuminated by ...

Perhaps not exactly the answer that you were looking for, but color is super weird and interesting and based on perception. The visual light spectrum is specific, colors have number identifiers, etc. BUT perception is where it gets really interesting to me. There are studies that show that cultures with more words for colors, are able to distinguish more ...

Now I don’t really know much about advanced science But I have some ideas... Is it not possible that iron oxides have enough oxygen in them to fuel a large amount or the combustion of the coal? So if you burn coal in the presence of metal oxide ores you will get pure-ish metal, some depletion of atmospheric oxygen, but something far more useful (carbon ...

As other answers have said, given enough resources (Methane), your proposed heat engine could work, however I wonder if there could be a more elegant design - especially considering that humans have mastered travel through the solar system. Since, in your world, humans are now expanding to other planets and moons I think it likely that through the ...

If spacecraft can reach Saturn in a month, then you have some sort of energy source which renders the problem moot (even if it is not fusion as per your OP, it has equal or greater energy density in order to propel spacecraft that quickly). The craft can orbit Titan and beam energy down via microwaves or lasers focused on cooperative power targets if you ...

Your moon orbits a gas giant but you say the northern hemisphere is cooked by exposure to the star. That would require a very odd orbital configuration (gas giant close to the parent star, moon in a polar orbit with the lunar north pole pointing towards the star and somehow tidally locked so that its orbit around the gas giant rotates once per planetary year ...

Enthalpy of vaporization of methane is very low - 5 times less than that of water. You will get about 5 kJ from 1 kg of methane. Even with low temperatures (about 100K ) "boost" to efficiency, it would not be above ~25-30%. So only 1.5kJ of energy from kg of evaporating methane would go to colony. One household (about 2-4 people) here on Earth need about ...

It sounds like you're trying to reinvent the Stirling Engine. If so, then yes it will work. To operate the stirling engine merely requires a greater temperature differential than is ambient in the environment. As soon as that occurs the engine will run and energy can be extracted from the system.

Dead, dead, and – you guessed it – dead. For all three of your scenarios, the astronaut would be utterly destroyed. The inside radius of the future crater is instantly vaporized. It temporarily becomes liquid-like and ripples due to the high energy impact. Nobody would survive within that radius. At the edge of the crater, the resulting shock wave and the ...

This 550 pound WWII bomb produced a 5 meter radius crater in soft farm soil. To make a 20 meter radius crater in moon rock would require at least the equivalent of several tons of explosive. The insta-kill radius is going to be at least 10's of meters out from the edge of the crater. Quite likely everybody within the distances you described is automatically ...

The overseer is helpful and should not cause harm. Think the overseer is not a king, but a representative of the planet to higher authority. Through the overseer, the planet to talk, request support from higher authority. The overseer should not interfere with internal affairs, unless it harm higher authority (profit, politics, ...). The overseer is ...

First things first: sometimes a critter or two may get past the dome's automatic defenses Build a decent wall around your site. You live in the future, you've got space travel so cheap that it makes economic sense to mine planets and export the minerals, you've got power storage devices that are dense enough to allow for handheld energy weapons, etc etc. ...

Democracy. The overseer is a nice guy. He pays his workers well. He does not need to be their overlord. In fact he does not want that at all - he is really good at the economics aspect and has reasonable mining skills, but he is not a leader of men. The overseer stays in charge of shipping and finance - he is a manager. Your people elect their own ...

A simple and cool solution is: • Give the workers only primitive (physical) weapons. So, the workers have free access to (awesome, really high-tech) crossbows - but they are just crossbows. They shoot a pointy bolt at very high speed. It's just possible to defeat the native vicious animals using these badass crossbows, and makes for good action. But. ...

Don't arm the masses, arm robots. That way you'll never have to worry about peasants revolting (as long as they don't have hackers). You may have problems with Skynet, but that's something else.
