This method would work, almost without doubt, on humans. There would always be some doubt in their minds as to whether the universe was real, so they would probably not kill everything. Probably. ...
Theoretically infinite, though the classification would get interesting. Consider the Moon. It orbits us, the Earth. That's a nesting of 0, right? Now consider the Earth. What's to say that the Ea...
It's hard to conceive of a star that doesn't supply itself by nuclear fusion, except those that already exist. Some background Nuclear fusion is a process by which two nuclei of two atoms fuse to...
On Earth: $$ a_G = 9.81\text{ ms}^{-1} $$ That's acceleration due to gravity. On a spinning torus, you simulate gravity by living on the outer edge and using centrifugal force, for which the form...
It is some small number of years into the future. We are regularly using beamed energy, as defined in this answer: large arrays of microwave transmitters. We have developed this so that these array...
As you say, just give them low-tech inertial dampeners. If you're using inertial dampeners to mean the same as I am, then we already have the technology to do this and it's used in many places. Ta...
The Technology We're in the year 2250 on an Earth-like planet. All the space on the earth's surface has been used up by the population of 15 billion, so we're moving into the air. Cities, along wi...
Does it differ from the early days of the internet - in another sense, would it be possible to handle with any protocols ever developed in the field of computer networks? No, that's not possib...
The prefix extra- is generally used for things that are outside of normality - for example, extraterrestrial for being outside Earth-normal, or extracurricular for education outside of the normal c...
Well, think about the direction in which each of these operations needs to go. Tunnels go horizontally across the mountain. Mines go more diagonally downwards, or even straight down in some cases....
Yes and no. It'd be worth keeping some of the larger telescopes around, simply because they have a wider area of coverage. A large radio telescope can cover a significant portion of its sky and li...
tl;dr: It can't be done. Meteors and all the various different classifications of them (meteorites, meteoroids) are small. The sun is big. More importantly, the sun is hot. If a meteor is heading ...
Planets can die, but it either takes a lot of energy and effort, or is very boring. Boring Planets can just stop working. As stated by some other answers here, if a planet has no life on it and i...
It would be brilliant. 30% oxygen atmosphere would mean that our human bodies have more available oxygen and would take more in in a single breath; this means that we would be able to respire faste...
This is my opinion on the topic. There is another point of view, as demonstrated by Tim B, but if you want to include humans in your story then perhaps this will help. The question posed recently ...
To expand on a point Sempie made, the colour of the ground determines how much light it reflects. White is the best reflector; black absorbs. This is why a black car will be hotter on the outside t...
Plants survive the night by producing excess energy during the day. This excess they then convert to starch and store. Research shows that chemical reactions in the plant's cells then calculate, ba...
Problem 1: Food This is the major contributing factor to the size of the biosphere. Humans need to consume around 2,250 calories per day (averaged between men and women) to sustain themselves, and...
Why would they live on a planet? These robots, with sufficiently advanced AI, could have a pretty advanced social system. They could have community leaders, followers, criminals even (if the progr...
You've touched on the major points already: vitamins and skin colour. They are linked to an extent. Vitamin D is the major vitamin we get from sunlight. It's partly a "happy vitamin" in that it pr...
As you say, the most sought after materials are the rarest. You also correctly assume that the rarest materials are often those with the greatest molecular mass. This is because it takes a much, mu...
I remember a book I read several years ago now, involving the Voynich manuscript. The basis was it was not decodable in any way - until a university student who happens to know symbols of another a...
First and foremost, not everyone would be able to survive. Much of it depends how quickly this warmup happens: if it's quick and the ice melts very quickly, people on the coast aren't going to get ...
You could certainly try. A less sensible method, if your local astrotech store sells them, is to get hold of a mass transporter and a matter inversion matrix (though in many timelines the latter c...
First and foremost, everyone would not be infected, let alone die. Look at Brazil and Peru and the tribes of the Amazon, many of whom still haven't been contacted. Since they have no human contact,...
