What thickness of atmosphere, and strength of magnetosphere, would I need for a planet to have a deadly daytime and a hospitable nighttime? I'm wanting a planet in which humans can survive on as l...
The square-cube law holds true only for objects that are similar. In evolution, you can't make big leaps forward, but since most fantasy worlds are created by gods or people who think they're gods,...
I´m building a hard-sifi setting and want to use Stellasers (abbreviation for stellar laser) to provide thrust and power to interstellar vessels. This part one is only concerned with the construct...

Larry Niven's "Known Universe" (KU) features "The Outsiders" as one of its most prominent alien races. As per KU canon, the Outsiders evolved in a frigid moon (similar to Nereida) and they sustai...
A launch loop https://en.wikipedia.org/wiki/Launch_loop is a proposed way to put lots of things into space at lower unit cost than rockets (only need to pay the energy cost in electricity for each ...
I was thinking about our history of music, came upon electronic music and started musing about all the possibilities of modulation and such. I then thought back to a previous question of mine, "Ho...
Cold and Flu, are common viruses which normally infect us in the cold of winter. Ironically, those people who always keep themselves warm, stay less out-of-the-house and office, keep their windows ...
In my Conworld, the inhabitants have discovered a type of star they cannot identify. I would like it to be a star made not from just hydrogen and helium, like our sun and countless others. But my q...
I'm trying to work out the parameters of my planet, using the spreadsheets that Artifexian has developed (particularly this Planet Calculator and this Atmosphere Calculator) as a guide. In order fo...
So I've been thinking for a while about making a world where cats aren't as common and instead are more of a regional domesticated animal, replaced in (mostly Northwestern) Europe by foxes. How co...
Of the six limbs of classic dragons, the forelegs always stuck out like a sore thumb. They're dead weight in flight, etc... However, since in my setting you can find any sort of armament, short of ...
In my world there is a village with a hot spring, the only one on the entire island. The spring emerges from a local cave which has been filled / caved in by a past civilisation, since the water i...
In my world there human-animal hybrids. My protagonist is a snow leopard-human girl (outwards looks almost completely human, except for the tail). These hybrids have been created through experiment...

In this world, there is a land isolated by a lava line, and the only way to get in there, is across a bridge levitated by hot air balloons. I had the idea of making a wooden bridge being supported...
Suppose we used SCP-261, the vending machine that produces anything, and ask for a cup of neutron star. The machine instantaneously produces this. Suppose also that the vending machine is located ...
