That's plenty possible. In fact, if you're willing to fudge your requirements just slightly, it could easily be the case for Earth's moon. Let's look at the equation for orbital speed, also known...
Moving things into low earth orbit might be an option. You could make your ten million dollars with only a single delivery to the ISS. The space shuttle cost \$1.5 Billion per launch. Billion. NA...
The answer to your question, regrettably, is no, and the counterargument is a classic one. The pole is composed of atoms and molecules and particles; it isn't one giant indivisible object. Those ...
Yes, and the planets can orbit in the habitable zones. This page gives a long list of planets in these S-type orbits, and states For a few systems (2 so far), there are planets orbiting each m...
So this is pretty complicated... Wind is caused by differences in pressure. Pressure is effected by both temperature and moisture. The more moisture, the lower the pressure. If the ice all melte...
Alternative answer; Studies show that sleep is your bodies way of purging out toxins and recharging, though a lot of it is still unknown. Instead of caffeine, what if the plant created an enzyme t...
I think it really depends a lot on the lay of the land. If the rainfall increases a lot then low areas with poor drainage would become bogs/swamps. High, well drained areas would probably thrive. A...
Look at Earth's biomes! When it comes to life and everything that comes along with it, we only have one data point, our own planet. Climate modeling is . . . hard. Really hard. When we're talking ...
Avoid helicopters and airships. Try the WC-130 or WP-3D. First, airships are not fantastic choices for maneuvering in high winds. Helicopters are bad enough, but airships are large and slow, meani...
Based on one of the comments in my previous question about What is the max size for underground creatures before the square-cube law takes a toll? Makes me want to know the limit size for a long c...
I am making a story of a species who lives on a planet several light-years above the Galactic Bulge. With advanced technology, how much could they see from their vantage point? Could they carry out...
The pillars are spread out about a mile apart each, and they all come straight from the ground, slowly gets just a smidge smaller in the middle, and then get bigger near the top, reaching a height ...
I would like to have giant sand worms similar to the ones in the 'Dune' novel. What should the planet be like so that they are realistic? Giant sand worms are roughly 100m long and 5 meters in diam...
Why I've Chosen Not to Handwave: The fictional galaxy in which this humanoid species (I'll refer to them as Empaths from here on out) lives is protected by a space-faring military/law-enforcing leg...
So, it finally happened. The Earth was hit by a comet, and anyone outside of a research station at the bottom of the Atlantic is now dead, or dying. So, here's what we need to know: How big would a...
In a near-future world we have stopped directly fueling private, public, and mass transit and we have migrated to a hydrogen economy as the standard energy carrier. Consider the following factors:...
Would a community of around 300 people be able to start producing plentiful food in ~5 years post a civil war and plague? They were an isolated quite wealthy community, in a sub-tropical area, mai...
Here is all you need to know about the creodonts: They were a group of carnivorous mammals that, despite having carnassials, had no relation to Carnivora. They were a global force, occupying terr...
I was thinking of an interesting landmark to put on my conworld, and I went with the "large body of acid" trope. This lake would be about the size of Lake Superior, and near the equator. The atmosp...
First these are ground effect vehicles, not true aircraft. While Star Trek, Star Wars, Blade Runner, The Jetsons, and every scifi I can think of has "magically hovering" private transportation, I a...
Just as the title, is there a scientific or possible way to extract past memory from a person brain into some record such as video or visual player ? I know some theory say that it possible to du...
Not exactly indestructible, at least after flying to certain height it may pop out. I mean something like the bubble is as hard as stone or steel but still elastic and light to float like bubble, ...
Assuming a passenger was sitting in an elevator in a rotating wheel space station, as depicted in the movie 2001:A Space Odyssey and based on this question Elevator on rotating wheel space station...
I'm fairly certain such a creature is impossible, but I was curious to see if anyone could come up with an explanation for such a creature. How would a two-headed giant evolve/function if it was a ...
I have a K-type star (0.5 stellar masses) as the central body, and the planets are as follows (those I want to be in the habitable zone in bold): I: An uninhabitable rocky inner planet 50% the mas...
