Good day everyone. I've recently finally gotten around to writing a sci fi novel but need help on some of the science of a few concepts I would like to incorporate in the novel. I'll start with ...
In my question: Sustainability of Regular Global Wildfires Due to Oxygen Rich Atmosphere An answer was proposed for a kind of "Boom Bust Cycle". The atmosphere has little CO2 but a lot of O2. W...
I was wondering, for a speculative evolution project, what could be the bare minimum amount of organisms the common housefly needs to survive? Could they just feed on grass? Or should I add a flowe...

Reptile reproduction, it turns out, is more flexible than our own. Whiptails, a girls-only species, can lay unfertilized eggs without the need for a male. And Komodo dragons have recently been di...
One of the planets I'm thinking of for my book series has all of its landmass in the northernmost half of the northern hemisphere (it is thus mostly a water world) and is completely geologically de...

We know that in biology, a species evolves to better survive its planet and its various climates and geography, which is mainly a result of natural selection. But, sometimes, this natural selecti...

Earth rocks are largely silicates, combinations of silicon, oxygen, and various other trace elements. What would a planets geography look like if the crust was primarily composed of ceramics like...
One thing that is fairly common amongst nearly every macro-scale living thing on this planet is the brain. The brain controls when creatures breathe, move, talk, etc., but the brains of said living...
In modern day society, few or many people have been fascinated with integrating robotic parts to their bodies. But sometimes that idea is taken to the next step, in which people want to have their ...
