The setting is a science fiction story set roughly 500 years in the future. Looking at Wikipedia, I see a number of baryons that have so far never been observed. I'm interested in exploring this s...
My idea involves an alien spaceship inside a roughly Earth to Mars sized/massed planet, but the whole planet is displaced when the drive is activated. If you wanted to travel back to our solar syst...
How long can objects made of hard material last at room temperature in otherwise ideal conditions? If left outdoors on Earth, over the course of millions of years, any material will be eroded by w...

For context, I was reading about various research groups installing implants and cameras onto insects to use them as reconnaissance drones in high risk areas. I'm wondering how feasible it would ...
