Note before I begin: I am aware that this might be a Math-heavy question that might be better suited for the math.se Goal: I'd like to use n-dimensional geometry as a method for effectively travel...
I'm writing about a world that predates most modern forensic techniques, and I am looking for some old-fashioned methods of sleuthing that would have been available at around the 1850-1900. In on...
In my world, I have a reptilian overlord theme, with humanoid slaves. The planet revolves around a binary star system. What are the basic requirements of the climate and the ecosystem, for the rept...
Humanoids with more than 2 pairs of arms weren't an unknown concept in human culture. From ancient mythology, there are the hundred-armed Hekatoncheires (who have their own thread here) and six-arm...
Biradial symmetry occurs in ctenophores: the body plan consists of two halves which independently display radial symmetry. Spherical symmetry occurs in Volvox algae: any cut through the center of t...
This seemed too scifi or hypothetical for physics, so here goes. Suppose a manipulated quark with 0 mass could travel faster than the speed of light. It's known that the faster you go, the slower...
This just out of curiosity and interest, could something like the marsupilami exist in our world? If you don't know, the marsupilami is pretty much a bipedal, arboreal monkey like monotreme (egg-la...
Consider centaurs, mermaids/mermen/merfolk, driders/arachne, lamia/naga, and other half-human creatures with similar bodyplans, which I will henceforth refer to as "centauromorphs". They all have a...
I understand this is a broad topic that to a degree was answered in previous questions. What I'm trying to do is to create a plugin in Unreal 4. I'll start by creating a day/night system and a sk...
Our Heroes are a small group of people around the level of the heroes of The Skylark Of Space. Operating on a budget of maybe ten million dollars, they've built a spacecraft with a mass somewhere a...
Accelerating a person's perceived sense of time is a fairly common subject in science fiction, and to keep a long story short, I was wondering just how far you could stretch time out when you're wo...
We know lasers right? Damn accurate, pew pew.... Meh. What I never saw, is using lasers to create pressure waves, to resonate something into its destruction. But Boeing even patented the plan of a ...
Please note that I have had some incredibly helpful and useful suggestions here that I have decided to make some major revisions as a result. I will reduce the overall atmospheric pressure and part...
How plausible would it be for an asteroid impact to create a hole through the Earth's crust into the mantle? What sort of traces would such an impact leave behind? Would it be survivable by at le...
Situation: A knight wants to kill me. I have a night to prepare. It will be a duel. Me: I'm a time traveler (and I ended up in the worst possible timelines of the multiverse) I have a laser w...
I was rereading The Restaurant at the End of the Universe, the sequel to The Hitchhiker's Guide to the Galaxy, and I came across an interesting passage: Flare riding is one of the most exotic a...
The DoomFleet returns! And this time, it's with a more "Conventional" weapon - That is, projectiles with an antimatter core. Ultra-simple explanation is they have a "small" amount of antimatter in...
Setting: In a fantasy setting much like World of Warcraft (where huge liberties are taken regarding the level of technological sophistication), an evil emperor rules from a castle in which there ar...
Is it possible for life to evolve"” and survive"” on a planet that is regularly hit by [relatively small"” usually no more than a few feet across when they make an impact] meteorites? If so, what e...
One of the ideas I've had for a story is to have million year old subterranean buildings/cities/temples which have younger architecture built on top of them, resulting in a "dungeon" which would be...
So, I know that the universe is expanding, and that that means that things are generally getting further apart as time goes on. What I'm having difficulty with, however, is figuring out just how mu...
Let's say there's a planet with 18 times the radius of Earth, but has the same density as Earth. If so, how would it be possible for a big planet to such a density of Earth? Would it have the same ...
Okay, so I have a sci-fi setting in which there is a form of FTL travel. Imagine the universe(all three/four dimensions of it) was stretched out onto the surface of a sphere. Now assume that ther...
I am familar with current reactor (experimental) fusion reactor design. But imagine a fusion reaction happening without a reactor, so there is no reactor hull to shield the sound from an innocent ...
In what ways could an island be protected from tsunamis, given the following constraints?: It lies in the middle of the ocean, at least several hundred kilometers from the nearest continent. It d...
