If I were to build a world like Game of Thrones, how would the dragons not burn their own nostrils from the heat of flames?

Let's imagine an Earth clone devoid of naturally occurring fissile materials"”and, for comprehensiveness' sake, also devoid of fertile materials like thorium and americium that could be used to pro...
If we made a large moon near Mars, the tidal forces would encourage the tectonic system to rev up again, and start up the inner dynamo effect. There would be volcanoes, producing a new atmosphere, ...
Suppose we detect a stellar black hole passing near the Solar system, and we have technology and time to send a manned mission to study it. Are there any experiments or observations that would hel...
Assuming that in the not too distant future space travel developed enough, that large numbers of ships and people were leaving the earth's surface on a regular basis. Would this ever reach a point ...
What would the orbit of a planet orbiting two stars look like? Would the planet orbit the stars simultaneously or one after the other? How strong might be the gravity well of such a system be? Any ...
Santa keeps his elves under horrid, appalling conditions. Working everyday of the year for little pay in the freezing cold of the North Pole. But just how many elves does he need? How many elves w...
According to a recent National Geographic article, astronauts returning home after longer missions suffer permanently impaired vision. This is a problem that must be addressed in hard-science world...
Giant Planetary Ring Bases (or GPRB's) are space stations built on planetary rings or are artificial rings themselves, such as Starship Troopers' Luna Base But are these super stations feasible?...
The normal condition of life in a planet (Earth right now) is that below us is the planet's core, and above us is the sky. Now if there's a hollow planet like above, is that possible? How does ...
So I'm thinking about an underwater civilization and everything related to it, and I got to thinking about how they would communicate over extremely long distance. I knew that underwater species l...
I have wondered what a terrestrial ecosystem would look like dominated by cnidarians and ctenophores rather than insects and tetrapods. In order to fulfill the same niches I imagine they would need...
Ignorance is curable, living is forever. Robert A. Heinlein1 Cutting to the hard data: Due to some or another reason2 the genetic information stored inside cells (aka DNA) of my Immortals d...
In the year 2588, ISRO (Indian Space Research Organization) along with collaboration of NASA had discovered a new planet named Accio several light years farther than Pluto. Scientists have computed...
There are craters that are permanently dark at the Moon's poles, since the Moon's axis tilt is so small that the sun never rises above the crater rim. On the Moon these get incredibly cold, since ...
[Edit: I'm not looking for 100% realism. I'm looking for an explanation as realistic as possible, possible with just few exceptions to physics.] [Edit 2: In my imagination these worlds are differe...
A civilization has a "magic" computer with memory and processing capacities far beyond what our physics says is possible. They decide to run a massive simulation of Conway's Game of Life with a ran...
Imagine a world that works mostly like our own: it's built of atoms and quantum particles, there's gravity and conservation of energy, etc. Perhaps the physical laws aren't exactly the same as our ...
According to multiple reputable sources, the idea of "photographic memory" in humans is a myth. While some people may be unusually adept at certain things involving memory - like remembering the la...
Detailed Synopsis: I started writing a story wherein advanced technology slowly stop working (starting from most advanced, and progressing until only handmade items function), while the global clim...
So, I created a planet that has a civilization that is beyond advanced. The planet's radius is 10x the radius of Earth, and is has the same density as Earth. What issues would I have with the grav...
We have these "magical" items everywhere in fiction; from the classic rabbit coming out of a hat illusion, to the TARDIS from Doctor Who, to Newest Magical Beast Newt Scamander Briefcase. These ite...
