In my alternate reality, Earth is not a planet. It is a moon and orbits a gas giant (however it has all of Earth's characteristics, it is also full of humans and life as we know it). This is the on...
Hypothetically speaking, if there was a substance you could drink/inhale (in an alternate reality) with superconducting properties, how would it influence the brain and the body? The superconduct...
The universe so far: If charged lepton fields are eliminated from the universe, charged pions become stable (having no decay path that preserves charge), replacing electrons to form bound "atomic"...
Let's say world is completely flat (infinite flat world, think minecraft flatworlds) for the purposes of the question. The gasses of the world started out in a grid pattern, with each square being ...
In our universe, in order for a cloud of gas to collapse into a star it needs to release heat energy in the form of radiation, so that it can cool down enough to collapse into a star. I read what ...

It's my first time writing an original story and I have this idea, but I don't know if it could be scientifically feasible. My story would be medieval fantasy with magic, but I wanted to add a twis...
Is it plausible that a planet can be breathable despite the color of it's atmosphere? My story takes place in an alternate reality in which what people thought the Solar System was like in the 50s,...
So, a little bit of pseudo backstory first. Imagine mother nature would be some godly being, that actually exists. Somewhere. In spiritual form. Now imagine humankind would be a big thorn in her ...
