Can a character perform telekinesis with energy manipulation? Perhaps. The answer could be yes, but only conditionally upon the character being able to manipulate: Dark Energy dark energy...
The most plausible reasons are solar radiation protection (sudden flares) and thermal management (less sun facing surface) as in the answers by hyperion4 and CatCat. Basically unless you decide th...
Depending on the story, these Y people could have the general look of drowned corpses at sea: bleached skin, slightly bleached hair, a general, incurable, swelling of the abdomen, circled eyes, col...
If the planet has reached an age where internal heat is no longer sufficient to maintain active tectonics, it will enter what is known as a "Stagnant-lid Regime". One of the first things that happ...
Biological lifelong pair bonding (monogamy). This is rare, but does happen. At least one reason males seek dominance in a society is to increase their access to mates, and thus have more children ...
I'll deal with the ambiguity in the question by providing options. What if a creature such as you propose evolved characteristics found in more primitive Earth creatures, how about "What if: It ca...
Been there, done that! This apparently happened already 1,500 years ago. Scientists at Cardiff University, UK, believe they have discovered the cause of crop failures and summer frosts some 1,500 ...
An EMP is probably not the right mechanism here - it will almost certainly result in large amounts of the precious smoke escaping from the sensitive electronics in the servers (and drives) but assu...
Pentoxifylline when co-administered with sodium thiopental causes death by acute pulmonary edema - or at least it does in rats! and is reasonably well-tolerated in most humans, with serious adverse...
Orbits Conventional wisdom says that terrestrial planets and hot Jupiters are not likely companions. These gas giants in close orbits aren't thought to form in situ, but rather to form further awa...
What is the maximum G-forces someone can stand COMFORTABLY? I posit that in order for someone to experience comfort that they must remain conscious, so the method by which people are transport...
You're asking about radically different things. Age to communicate via the vocal cords? Zero. All (normally developing) neonates can communicate via the vocal cords. Screaming, etc. Initially,...
Is it possible for an organic species to generate a steady magnetic field? Hemochromatosis: The human body cannot rid itself of extra iron. Over time, these excesses build up in major organs...
As several answers say, this is impossible. One solution is to (very early in the book) attribute the construction to a previous advanced civilization with mystery tech capable of this feat. A mor...
My first thought when reading the question was that you were describing a sudden end to human life followed by (or at the same time as) an alien landing. Could the alien species reverse-engineer o...
If they aren't necessarily equine, and can have things like cloven hooves, why not have prehensile hooves? Prehensile hooves don't exist in the real world, as far as I know, but then, neither do u...
As an interesting aside, it's worth mentioning that, at certain points in history, humans have had a similar lifespan to what you're proposing. For example, the average life expectancy from birth ...
Nothing says the orbit of your planet has to be as close to circular as the Earth's. All orbits are elliptical, with the sun at one of the two foci. (Even a circle is an ellipse, it just has both f...
How can a person be kept alive while being periodically drained of blood? The way the question is framed by the context that you've given leads me to show this: My answer is speculative and in no...
Are you able to send graphics? Or print them. If GPS coordinates may not be meaningful in 1000 years, why assume that your use of English will be? (Or any current language) If they can find the...
Your massive maglev train is, obviously, levitated and accelerated by (electro) magnets, and must be many times the mass of the spaceship. The energy to power those magnets must come from somewher...
At an atmosphere 20x denser than Earth's and with gravity 0.85x that of Earth, could organisms which have the traits above float by means of a huge bladder of hydrogen gas, producing the hydrogen v...
Would a society with two different species that can interbreed be viable? Sure it's possible, by a number of processes the most obvious being hybridisation. The process by which two distinct speci...
Can I have a glacier on a tidally-locked shallow-sea planet? Yes. One of the outer system planets, somewhat like a large Jupiter could be a small star: It takes a little over .08 of a solar m...
How to create a genetically high IQ population while avoiding regression to the mean as much as possible? To avoid the leveling drift (regression to the mean) in a population, what you need to do ...
