Back home, the Tibetan Plateau averages 4,950 meters above sea level with its highest point being Mount Everest, 8,848 meters--29,029 feet--above sea level. At such heights, problems are resulted ...
There have been more than a few questions covering Alcubiere warp drives, many about what happens with one at FTL and a few about using them at sub-light speeds. I'm curious about what happens at ...
Sort of an extension of With minimal terraforming, what features/structures would need to be built to protect a 25mi radius city from wind? but with some more items to consider. For whatever re...
This post: How to increase air density on a planet? explains most of the problems I have been having, and fixes them. My current problem is as follows: On a planet with an air composed of (roughly)...
I'm building a fantasy world with a planetary core that gains and loses mass in a predictable manner. I want the gravity to increase and decrease by 50% in both directions over a period lasting 2-3...
On one of the continents in one of my fantasy worlds, I have a kingdom. The kingdom is comprised of two different geographical regions, a steppeland area in the kingdom's north and a desert region ...
If the earth gravity fluctuated between +50% and -50% over the course of 200 years, what specific adaptations would be useful to account for the change?
I'm making an alien race that's kinda like the Tyranids. My problem right now is that they're starting out on a planet. How would they actually leave this planet using only their biological abiliti...
I've been playing a lot of Deserts of Kharak lately, and I am wondering if landships depicted in game, which are essentially seagoing ships on tracks, would work in a Snowball Earth scenario. By Sn...
CODE DRIVER In my story, I want to have a world in the middle of a zombie apocalypse, but I also want it to feel different from any other interpretation out there. I call my monsters "Odd People" ...
I love the game Inside. Like its predecessor, Limbo, it is a game where you cannot fight; only running and hiding are allowed. The game ends however, with you coming across a large ball of meat str...
I want to create a world where tying yourself to a single partner would be considered irresponsible because it is potentially deadly. The more often two people come together and exchange DNA throug...
I'm looking for answers that focus on changes in internal anatomy that allow humans to survive in a high-g environment. If dramatic visible change can be avoided, that'd be great. Problems Circula...
I'm working on a science fiction story involving starships travelling about 95% of the speed of light. I wanted to have a reason for the starships to need to shield themselves against time dilation...
If the mass came from handwaving and just increased the core's density, what would happen to the plates? If, over the course of 200 years the planet fluctuated from +50% to -50% gravity, would the...
I have a world with a moon, much like Earth and the Moon, except that the planet is almost tidally locked to the moon. The moon therefore appears to move only very slowly through the sky, and take...
Humans (and mammals) have 2 lungs, one right and the another left. The right lung has 3 lobes and the left have 2 lobes because in the "third" there is the heart, so the right lung is bigger than t...
Just last week while developing a new CCTV camera system I accidentally produced a free energy generator. I know, what are the odds? So now I'd like to make some money. Unfortunately, this device ...
I'm working with the idea of a 'ring station' encircling a planet, as a tightly connected belt of structures that connect in orbit around the planet's equator. I'm curious to know what would happen...
My habitat ring is constructed in orbit around a planet with disconnected sections: (not to scale, obviously) The sections are connected by cables and winched together. As the diameter gets sma...
Have been building a game called Rise: The Vieneo Province. Vieneo is a terrestrial moon (all details can be found here) but we have an atmospheric composition we arrived on from another question:...
I'm creating a fantasy planet with an interior that has a god phasing in and out of our dimension, adding to and taking away mass in mysterious fashion while keeping everything but the influence of...
If Humanity were to suddenly come to its senses and stop relying all together on fossil fuels and start relying on wind powered and solar energy sources, wouldn't this lead to some sort of climate ...
Could a species, over centuries of evolution, evolve a special organ that stores pure energy and allows it to control its own magnetic field? What possible steps would have to happen for this to oc...
So this question, Designing a Carnivorous Plant, talks about animals being attracted to a plant, at first by a sweet scent, and then being drugged by an unspecified toxin which renders them 'euphor...
