I'm wondering what adverse effects might be felt by someone from a planet with, say, 80% of Earth's gravity and a denser, but breathable, atmosphere with a higher concentration of oxygen visiting a...
Would something like this be feasible? Span of bridge is approximately 5km. Height above canyon floor is approximately 800 meters (1/2 mile). Bridge structurally close to neutral. Tethered dirigi...
Given the resources available on Earth, can we erect a colossal cage to envelope the entire planet? [Conditions] must covers the entire globe in a single non breaking element. brave any kinds of...
Ignoring the fact that we need water in order to survive, what would happen if all of the "oceans" on Earth were filled with a dense non-reactive gas (e.g. xenon or sulfur hexafluoride) instead of ...
Can the gravitational pull of Earth drag the Moon into Earth's atmosphere? Likewise, can the gravitational pull of the Sun drag Earth into the Sun's atmosphere? If that can happen, what will happen...
Let's say, we've surpassed all tolerances of population. But, mega-corporations found a creative way to solve the problem. They dug into the Earth to build bubble cities in magma. They have access ...
Is it possible for complex life to exist on a planet with no tilt and no moons, and be so close to its sun that the equator would be far too hot to cross on foot and still survive, and its poles fa...
Lets take a 60km radius island where the people have access to early XXI century technology. The whole island was planned and artificially built, so it has no mountains or otherwise bad/sterile ter...
See this question for further details I also know how unlikely this situation is, so please refrain. From telling me "it won't happen." Jupiter is sent on a spiral into the inner Solar System. Bo...
When you look at the history of earth, the last ice age had major impacts on the flora and fauna of the world as well as biological migration. If I am creating an earth-like world and am developin...
Got this idea from Antarctica in the Legend series by Marie Lu Imagine that we've become so technologically advanced that every person, ages 3 and up, has an implant in their head that tracks ever...
Obviously there are plenty of potential physics problems with this scenario, but if people lived along the inner crust of the Earth, and there was a Sun-like core at the center with nothing else in...
I am creating a fantasy world where a given race is mystically tied to the planet. Predominately this race will be earth-dwellers, quite happy and content to burrow underground, but I'd like some o...
Let's say you were living on a planet near (but not too near) a black hole. I'm thinking of the planet Miller in the movie Interstellar. Obviously there are some strong tidal forces. But at this d...
Looking at the recent questions on dragons and aviation bureaucracy has got me thinking about some animals I could include in my story. I want these animals to be jet powered. One of the answers o...
I was wondering what would happen if you attach 2 Huge ion engines(I mean really really really huge) to planet earth. They should be attached on the north and south poles. Are 2 huge ion engines ...
How would plants be affected by a 48 hour day, instead of 24 hour? Would plants be larger to store more energy for photosynthesis? Also, how about the temperature of the earth be different on bot...
What would it take in terms of impact size to interrupt or stop Earth's (or an Earth-like planet's) magnetic field?
While we develop space travel technologies, the Moon will always be the first destination. By its proximity to Earth is the obvious target to test our technology. Before we can establish some kind...
My question is mainly related to the impact on food production if the climate changes made agriculture more difficult in the state of California but also in the other American and Mexican states fr...
Assuming planet Earth, with considerable amounts of pets per household (96 million cats in the US alone), what would be the social and ecological consequences of all domestic cats acquiring flight ...
What kind of a scenario would have to occur in order for human beings to seek survival on the sea floor? It could be man made or natural, ice age or heat apocalypse, sudden disaster or gradual coll...
As the title suggests, what happens to a planet geologically and geographically over time? This question came to mind from the many sessions of Civilization I have played where when you set up a c...
