I once before asked a question on how to quickly submerge a large landmass/continent. The answers there basically concluded that literally ''Sinking'' (a la Atlantis) is pretty much impossible to...
If it were possible to build a giant geodesic dome tens of miles in diameter, what effect would it have on nearby weather? If built in an arid climate like the Sahara or Australia, would it be li...
In the world my friend and I are making, the dark lord makes one of the planets uninhabitable by causing a moon, about the size of our own, to fall on it. About 7000 years later, it is unnaturally ...
I've been recently looking into alternative biochemistries for life and the environments were these could be found. I already asked a question about how ammonia oceans might form a while back. Toda...
A part of the story I am writing involves two continents that centuries before the story takes place sunk into the sea. I want to have a way to explain this that does not come down to just the sea...
I'm conceiving of a world where humans can readily terraform worlds that were once considered "dead" due to the planet's magnetic field being long gone. In such a situation, what could humans do t...
Writing about suspended cities within a planet's atmosphere! The story itself focuses on the air forces that fight for each of the hundreds of floating city states living in the sky, but that's her...
You know stuff like Yggdrasil tree but just a normal tree that is the biggest and tallest in the world. If the roots grow to surpass the continental and oceanic plate either it only cover some par...
Update (6/20/19): I have received some great answer here and they all mostly point to the fact that while effects on the opposite side of the planet are possible, the deformation may or may not re...
I'm talking about this sort of liquid sand: https://www.youtube.com/watch?v=My4RA5I0FKs "Desert-as-sea-analog" is present in many media, but often they lean heavily into fantasy, and it seems not ...
The established fact is that the shape of a planet's continental coastlines is determined by the planet's climate. Higher temperatures mean less ice, which ultimately means higher sea levels. (Ca...
How many rocket launches are needed to change the axial tilt of the Earth so much that it is noticeable with instruments available today? We can assume that we are talking about the heaviest rocke...
Premise: a massive organic structure sits somewhere in the Atlantic Ocean giving of an intermittent telekinetic pulse. This would presumably create a constant chain of tsunamis. What sort of abnor...
Assuming that there is an Earth-like planet that has 8 times the volume, 2.83 times the radius, and has the same surface gravity as Earth, and has oceans; what are potential problems concerning the...
I'm working on a earth-like planet with a much lower sea level (like 3000m so the mid-ocean ridge would form many islands) but is that even possible? Will the emerged ridge make some weird stuff an...
Essentially, what would be the most efficient way of causing the Earth's core to cool as much as possible without damaging human civilization in any other way (the outcome can damage it, but not th...
Could a natural satellite in geosynchronous orbit be used as a counterweight for a space elevator? Does the counterweight need to be of approximately the same weight as the anchor? If so, I suppose...
For my world, I would like a coastal mountain range that partway along its length is offset by a few (say, 100) kilometres, forming a pass through the mountains, like so: (N.B. I've drawn this ...
This is a sequel to my previous question How big could a moon be before its orbit became too unstable or tidally locked to its planet OK, let's imagine that the thing everyone thought was a moon w...
